NOTES AND QUERIES.

Questions for reply in coming issue to be received not later than Alf/XDAF nifit. . Htpo. — The blistering of yoiu prints presumably ariees from the fact that the hypo bath- is coldei in temperature than the final trash water. Hypo ■when dissolving has a cooling effect on water, therefore the fixing bath sbou'd be mixed a few hours before use. Another method would bs to add a Biiw.il quantity of alum to the fixing bath, but this is better avoided. A. W., Mataura Island. — The age limit for a railway engine cleaner is 18 year.s last birthday. Application forms can be obtained from any stationniaster. Student.— <Mi a. R. Barclay. L-L.8., kindly replies that the books which an extramural student would require to read to qualify him-self to ait for the Constitu- . tional History paper for the B.A. degree are as follows: — History section: Taswellliangmead's Constitutional History and Feilden'a Short History. Law section : Portions of Sir Wn. Anson's book on the Constitution. The first two are most necessary — the latter is not absolutely essential. The University class examination may be passed without readme it at all. But for degree work it is highly advisable to study the more important portions of Ansoc's book. C. C— Thank you; it is very amusing. "Will probably appear nsxt week. Witness Svbsckuheb. — If , genuine it unquestionably is valuable. Antonio Stradivari, the fauved violin maker of Cremona, lived 1619-173f. He was the pupil o£ Nicholas Atnati, and carried the Cremona type of violin to its highest perfection. The prices of the best violins of Stradivari and Gresu range from JS2OO to £500, but several have exceeded the latter figure. One was sold at Stuttgart at the fancy price of £2030. ' Übalite. — We do not know of any agent for Cr&lite- roofing in Dunedin. but Messrs Howison and Co. are the agents for Paroid, and Messrs Denniston and Co. for Ruberoid. v^ Mines. Nevis — Mr H. M. Davey. Stokes,* Buildings, Princes street, replies: — I do not think that'ymi would lift 30ft as you have arranged the nozzle, siiice you lift entirely by suction, and are considerably above the sea level, which makes a difference in the lift. But you can sink tho shaft as soon as you like, for it can be drained even if it were deeper than you say, by tho very same arrangement, only placing the nozzle lower down. You have ample pressure — you say 250ft — which will foB increased by the depth of the gliaft to nearly 300 ft at the bottom oi the shnft. You might say if you have any pipes, and if so send a template of the position of the holes in the last one for making the nozzle pipes to fit. • You see, you do not say exactly what you want to ask a price for. Do you need the jet pump only, or piping for both the pressure and pump uptake, or delivery pipes? These alone would be, say. 90ft. Anyhow, I will get quotations for you in a way -that may suit you by asking for the prices of the jet pump and pipes separately. Subscribes, Warepa.— The age limit for a junior porter on the Government railways is 18 years last birthday, and for a labourer 24 years. In both cases a Fifth Standard education, is sufficient. Gonstaht Readeh.— The answer to your query ia contained in section 40 of " The • Public Health Act, 1900," which runs thus : " The reasonable expense of maintaining and treating in a hospital any patient who is not a pauper shall be d-eained to !■>» a debt flue from the patient to the local authority, trustees, or other body by which the lio=pital is maintained., and may be reccve/ed -j;uordinrfr*"
