IRELAND. (From the Times, August 15 )

The Arrest of Messrs. Mkagher, O'Donoghue, 4f AND LEYNE. ' Thurles, 6. a. m., Sunday. — Latt night, between 1 and 12 o'clock, Mr. F. H. Meaner, Mr. P. O'Donoghue, and Mr. M. Connor Leyne, were arrested near the railway bridge, on the road between Rathcannon and Holy Crosi. The arrest Was effected by constable F. Mrtdden and Mir police patrol from Rathcannon, whither the prisoners were at once conveyed. On being searched there, neither arms nor papers were found on their persons, so that they seem to have anticipated the probability of being taken. This morning, soon after 3 o'clock, they arrived in Thurles, where they were safely lodged in the police barracks, while their escort proceeded to route Mr. Bracken, sub-intpector of police for this district. Mr. Bracken had the prisoners taken to hit house, where they had tea, and Wdihed and shaved. In the mean lime some constable! were Bent back to the spot where the arrest was made, in the hope that Doheny, who was believed to be in that neighbourhood, might also be seized. , Messengers were also sent to Mr. Gote Jones and Mr. iw f itzmaurice, the resident magistrates, and to General I Mscdonald. With the utmost secrecy the necessary " steps were taken for removing the prisoners at once by special train to Dublin. Mr. Bracken, and a couple of policemen behind him, walked quietly down to the station with Mr. Leyne, while Mr. Gore Jones, in an equally unostentatious way. escorted the other two prisoners. Some slight delay took place in getting the engine ready, and during the interval the three captured confederates walked about the platform, and appeared tolerably uelf-poiiessed. Mr. Meagher, 1 thought, looked a little sorrowful, but, when spoken to ( his manner became perfectly cheetful, and it is quite clear that the leport of his labouring under fever was without foundation. He was dressed in a blue surtout, buttoned up, and trousers of grey tweed. He wore a " wide-awake" straw hat disposed rather theatrically on his head, «nd his tout ensemble gave me more the

idea of a " iwell" than a gentleman. Hit appearance is not vulgar, but " pretentiom," and you see in it at once the usual characteristics of an ad captandum orator. O'Donoghue is a very different looking person from Mr. Meagher, and combines in his face all the tiuckulence and ferocity of expression that onn might look for in the leader ot an insurrectionary movement. His features are enormously Urge and coarse, conveying an idea of savage obitinacy, such as would admirably suit the top of a Parisian barricade or gome other ■cene of sanguinary and relentless slaughter ; he wears no whiskers, and the sallow complexion of his face is rendered more repulsive by the puckered seams and hanh lines which extend over it. He wore on his head an immense fur-cap from beneath which appeared the stiff ends of his back hair, descending in ungainly tufts, anJ adding to the extraordinary ugliness of his countenance. His clothe* were a cut-away black coat, seedy from wear, a dirty light waistcoat, and a pair of dark trousers with a light blue stripe down the side. The manners of thf man corresponded exactly with his features, and his thick-set and clumsy proportions. He seems to be about 45 year* of age. The last of the prisoners, Mr. Arthur Leyne, is quite a young man, and there is nothing remarkable in his appearance, but an expression of billy enthusiasm. He is the son of a stipendiary magistrate. The three wore top-coats of frieze, probably made in the Silver Mines, and vhe'her it was done intentionally or not, I must say that a more ill-looking &et, or one more likely to draw down the attention of the police, it is hardly possible to conceive. At twenty minutes before seven o'clock the train started for Dublin, the departure of the prisoners being at the time scarcely known in Thurles, and the whole 'flair being conducted in the quietest manner possible.— General Macdonald sent Captain Mackenzie, one of hit staff, up to town in charge of the prisoners. In the same carriage with them also sat Sub-Inspector Brack, en, Mr. Fitzmaurice, resident magistrate, your reporter, and a single armed constable, who was in charge of the four men by whom the arreit was made.— O'Donoghue amused himself during the journey by " chaffing" the policeman who sat next him, and who, under the circumstances, looked much more modest and abashed than he probably did in the execution of his duty some hours before. Dublin, Sunday Morning.— On the arrival of the train the prisoners wsre at once conducted to the Royal B irracks under an escort of twenty of the Thurles constabulary. Captain Mackenzie having seen them safely deposited in the Loyal Barracks, proceeded with despatches fiom General Macdonald to the Viceregal Lodge. I am requested by Mr. Meagber to state that he never acceded to the terms of surrender proponed on bis behalf by ths Rev. Mr. Mackey, and that the nature of the propotal m»de by him must hive been mistaken by tint gentleman. He never wuhed, he said, to bargain for his own life, and had been greatly annoyed at what had appeared in the Dublin Evening Mail on that subject. Mr. Meagber told me that he had heaid of Mr. O'Brien's arrest on Sunday evening. It will be seen by this that his companions have had early intelligence of all that has been taking place, and that they have therefore less credit for looking confident and self-possessed than poor Smith O'Brien. M^. Fitzmaurice, R. M., has been sent for from the Castle, and came up to Dublin by the express train o 1 some business of importance. THE ARRESTS. Dublin, Monday Morning — When the intelligence became known yesterday morning that Mr. Meagher " of the Sword," was an inmate of Ktlmainhim Gaol, the circumstance created marvellously little excitement, considering the prominent position this ill-fated young manhssoccup ed in the political history of this countiy for the last year or so. Not but that Mr. Meagher is eminently popular as a revoluti mary leader, but the truth is, the spirit of rebellion which ran riol one short fortnight since, is completely broken by the arrest, without a struggle, of Mr, S. OBrien ; hence the abience of any marked sensation in the case of Mr. Meagher. Mr. Maurice Leyne, his fellowcaptive, is nephew of the late Daniel O'Connell, and remained a member of Conciliation -hall until within a very recent period, when he suddenly shook off the shackle* of moral force and threw himself into the ranks of the Republicans. He is in years about the same age as Mr. Meagher, and his oratory, like that getleman's, is of the most florid style, and his speeches might, at any time, by a slight stretch of ingenuity, bs readily turned into blank verse. The third party arrested yesterday (O'Donoughue) is an attorney's clerk, and a man who was always regarded with suspicion by the Confederates. He is possessed of a fair •hare ot natural talent, which was evinced in the publication of several letters written during the beat of the late agitation. The following letters from the south appear in the Ntiuslelter of this morning :—

" Abbeyfeale, Saturday, August 11, 7 a. m. 11 Nearly 2(0 of the 88th Regiment, 200 of the 64th, and 150 constabulary are encamped here. Quarter-niaiter-Gencral Cox is also here, providing accommodation for nearly 3000 men. The commissariat department is to be arranged, and the ground for the enlarged encampment has been fixed upon and marked out. "The inhabitants here have refused to supply the troops or police. The most enticing offers of money payment have proved ineffectual to induce them to supply provisions. Mr Coppinger is in charge of ihe : police; they are htrrnised with heavy duty and bad accommodation. The letter bags which were taken from [ ihe mail coach have all been returned empty. InforI nut ions have been lodged against several parties who s>re known to have taken part in the robbery. The following is the mode in which the bags were returned:— A. .little boy was sent by G'Gormau to the postmaster to say that if he would (tend to a certain ! house the bags would be found there: The postmaster did send and got the bags. Ten men have been arrested j for the robbery, and seteral others will, it it expected, be arrested to-day, •* Sub-Inipector I'oppirjger met a body of armed men the other day, who threatened to shout him if be continued his search for O'Gorman. The sub-inspec-tor was alone, and did not wish to show fight to such a large number of armed ruffian*. " I am informed a large body of Soldiers inarched into Rathkeale this morning at 5 o'clock,, k. m , from Limerick."

•' Abbeyfeale, Sunday, August 3. " I was prevented finishing my letter yesterday by the announcement of the mail, to I had to break off short, and had much difficulty to get it sent by that post. I have now to tell you tint O'Gorman has left this part of the country. Doheny came to meet him here on the mountains, but was met by O'Gorman, who carried his own carpet bag, and was alone. He told Doheny that thingi were in a hopeless state herr, and that further attempt to raise the people would be fruitless. He succeeded in persuading Doheny to return, and both went off in the direction of Keeper Hill— They are cloiely traced by the Detectives. O'Gorman planned the coach robbery, but did not act in it himself. They (the leaders) ars altogether on Keeperhill, and there is no truth ia the report of the eicape of any of them gut of the country."

" Clonmel, Saturday evening, Augutt 11. " Lord Hardinge and suite arrived here to-day, buc after a short delay at the Globe Hotel for refreshment, they started for Limerick, where 2000 troops are concentrated, of whom his lordship will take the command. Though short the time that he remained here, a considerable crowd collected, all anxious to get a look at the hero of India and the companion-in-arms of our own Lord Gough, who if from this immediate neighbourhood. The old soldier looked brave and heart)'. "We are all waiting for the special commission with great anxiety ; there seems to be little doubt of its being held here in two or three weeks; that length of time, at least, will be reqnired to make the necessary preparations in summoning of jurors, &c. The men who were captured at Ballingarry will be tried here, at the commission, should there be one. " Tliere coutinues a perfect quiet in this part of the country; no symptom of outbreak or disaffection is now apparent; in fact the preipnce of an immense military foice has made the people wonderfully loyal. u 6 o'clovk.— a man named Walsh (a tailor) has just been committed to Clonmel gaol by Mr. Charles R.M., Tipperary, having been arrested at Bansha, with letters in his possession for Doheny and others of the conspirators." THE PRELATES AND THB REBEL CHIEFS. The clergy of Archbishop M'Hale's diocese are the first in the field as mediators on the part or Mr. Smith OBrien, a vast body of them having signed the following memorial to the Queen on behalf of the un» fortunate gentleman :— «' May it please your Majesty — We, the Roman Catholic clergy of the diocese of Tuam, in Ireland, moit respectfully approach your Most Gracious "Majesty with the expression of oar unbounded attachment to the person of your Majesty, and of eternal loyalty to the] throne of these realms, whicn is occupied with so much dignity by your Most Gracious Majesty, humbly praying your Majesty's benevolent attention to the unfortunate scenes now acting in this portion oi your Majesty's dominion!. We beg to assure youi Majesty that we do not yield to any class or portion of your Majesty's subjects in sincere and conscientious loyalty to your throne, and devoted attachment to your molt gracious Majesty's royal peißou. " We have witnessed with pain the proceedings of a few inexperienced young men for some months past. We disagree with them on principle. We denounced them at the enemies of order, religion and their country. Yet we now feel commiseration lor their folly as intensely as we felt indignant when we beheld them car ried away by the impetuosity of their ardent but erroneous aspirations for liberty. We trust it is unnecessary for us to assure your Majesty that in the trying period of the last few years of unexampled dis"treisaud destitution, when death itared us in every shape— starvation, hunger, and its contomitant, typhus fever— -we braved all, and never ceased to exhort our flocks to resignation to the Divine will, and to strict obedience to the laws of the land. We then confidently hope that your Most Gracious Majesty will be pleased to take into your merciful consideration the unfortunate situation of Mr. Smith OBrien and the other unreflecting; persons who have to foolishly embarked In the late lamentable outbreak; hereby proving to the world their utter insanity. 41 The prerogative of mercy is the brightest diadem in your Majesty's glorious crown. We, the loyal and iaithful Roman Catholic clergy of Tuam, appeal to that ■ noble attribute oh behalf of the deluded William Smitu OBrien and his deluded and misguided associates, and beg to assure your Majesty that the exercise of mercy on this '.occasion towards these unfortunate culprits will secure to your Majesty and throne wore of pure and true loyalty than the sliedd'iDg of the blood of thous>tuds. Rest assured the heart of Ireland is sound and true towards your gracious Majesty — -hence we implore, we entreat, nay, we most humbly beg— 4 ' no blood;" uiid ai ministers of religion, whose sacred duty it is to inculcate peace and good will amongst men, we ' further beg to assure your Majesty that the concession of the prayer of this our petition shall be an additional stimulant to us to uphold the laws, and to secure, even at the sacnuue ot our lwes, the stability of that Throne which is so happily occupied by your most Gracious Majesty; and your memorialists will ever pray, &c." MORE ARRESTS. \ A person named Sexton, conducting clerk to an eminent solicitor, was arrested yesterday on a charge of treason. He was vice-president ot the Gi'attun (Mr. Meagher's) Club. ' Sergeant Gargan, of the detective po'ice, succeeded on Saturday in arresting, m Morgan-place, Richard ' Franks Ryan, an American, in whose possession paptrs were found appointing him a delegate for England, Ireland, and bcotland. The train which arrived at the King's-br'tdge sta- I tion at three o'clock yesterday brought up Mr. James F. Lalor, who had been arrested same day« ago and ' confined in Nenagh gaol, under the escort of headconitable Hayes. The prisoner was accompanied from the termmui to Newgate by a party of mounted police. He was brought up under a warrant of removal, it having been notified to the Crown on the part of Air. Martin, one ot the state prisoners, that he would be required as a witneis on his behalf. Two American sympathizers, named M'Dade and i Macnamin, were arrested in the county of Donegal last week, and committed to gaol. I THE ABBEYPEALE OUTRAGE The Limerick Chronicle gives the subjoined authentic particulars of the circumstances connected with the i capture of head-constable Hogben by the insurgents, at Abbey feale, on the 3rd inst. : — '• He was proceeding from Abbeyfeale to Newcastle, and when about a mile from the formtr village he was pursued by some of the rebel cavalry, and a crowd ot about 300 persons, variously armed, under the command of a man named Harnett, who iorcibly took from him the articles mentioned in our last publication. They threatened him with instant death, saying ' Mitchell got no mercy, and he shall get none.' The headconstable replied that they were unworthy the name of Irikhmeo if they took away the life of a single man • that he was not afraid of death, but would die, as a policeman ought, in the discharge of his duty. They said, the first duty he owed was to his country, and that he should be treated as an enemy to it. At this juncture «he Rev. Mr. Lyddy, Koman Catholic priest of Abbeyfeale, rode amongst the crowd, and remonstrated with them, and asked Hurnett by what authority he was thus acting. Haruett replied — by a higher authority thau he was aware of; that he had better look to himse f ; that he was well situate under the present government, and couaequtntly did not wish for a change. Others threatened him in a violent manner, saying * Look to the first French Revolution, when the priesthood were put down.' The headconstable was then hurried to the mountains by an armed party, who frequently threatened to shoot him. One who was barefooted said he was captain under 1 General O'Gorman,' and atked the head-constable did he know anything of guerilla warfare, and if that nai not a beautiful country for engaging the military.

Tha party al»o asked what wis the hpad- constable's opinion as to the u'timnte saccess of their cause. He replied, that they were running lo certain destruction ; that they were so weak and so divided amon? themselves that they could not have the smallest chance of lucceeding. The barefooted captain replied that he was satisfied to die. provided he could fust follow Father Bermingham's advice— that is, to take down two men before he fe'l himself. In the evening Harnett and another leader, who seemed to have go' new orders, came to where the head-constable was detained, and told him th;it his life was safe, and that if they insulted him they were sorry for it, and that h«* might return in safety to Abbeyfeale. He accordingly proceeded there, and was again attacked by the mob, hut finally, by ihe assistance of some of the well-disposed inhabitants, succeeded in escaping to Newcastle. "Yesterday an order was received from the Postmaster General suspending the guards of the Tralee and Limerick mails (Galvm and Purcell) until an investigation takes place inio their conduct, for not resolutely resisting the attack of the insurgents who robbed the mail bags, and carried off the coach arms at Abbeyfeale, on Saturday last. It is our opinion that the lawless multitude would have destroyed both men instantly, had they fired uj.on the occasion of the coach attack. Inquiry will at once show the utter futility, if not madness, of rcsiitance. Galvin and Purcell have had each 22 years' service, were rated on the Ist class guards' list, and had been uniformly correct, Ueidy men. '• Air. Harnett, who is charged with attaching the Limerick mail, at Abbtyfeale, has absconded ; Michael Demston, leader of the party, was yesterday fully committed to our county gaol— he is also charged with threatening to lire at head-constable Hogben, by whom he has been identified. " Immediately after the mails were stopped ab Abbeyfeale, a party of insurgents visited the bouse of the Rev. Edward Norman, rector of Brosna, and demanded his arms, when the reverend gentleman informed them that he bad none. The party seemed satisfied, but acting under superior orders, one of them I made a frunles* search, behaving all the time with civility. A few hours afterwards another paity of about 100, marching four deep, the front rank armed with fowling pieces, which they carried ' bloped,' drew up in front of the parsonage at the word of command, and arms'were again demanded. Upon being informed that there were none, and that the bouse had been already searched, they faced to the right, and inarched towards the village of Duagh, wheDce they had come. Shortly after learing, some shots were fired by this party, directed towards Mr. Lydan, a scripture reader, who wanuspected of having firearms in his possession* Fortunately he escaped without injury. |A strong party of the younger peasantry of the parish of Duagh, lying farther dawn ia the Feal river, set off for the county of Limerick, to join the insurgents, having first robbed Springmount, the residence of Mr. Fuzmaurice, of arms. On Sunday and Monday the mails were escorted by a party of the 88th Regiment, and every day since have been guarded by police. There hai been no appearance of the insurgents since in any force j but each night they visited farmhouses, and secured a small quantity of arms.
