VETERINARY QUERIES.

[■Answered by a duly qualified Veterinary Surgeon. Queries must be received by SATURDAY night to ensure reply in the succeeding Issue.] Dairyman*.— Cow with contagious abortion : The specific nature of the abortion contagion a few years ago was discovered by Professor Nocard, who found in the uterus of cows which had been aborted, and in the alimentary canal of aborted foetus a distinctive organism, winch, although carefully looked for, could not be found in healthy cows or in the digestive organs of calves carried to their full time. These organisms are believed bo enter the genital passages, make their may into the uterus, and multiply between the foetal envelopes.“breaking up the connections between mother and offspring. Based upon these observations, the preventable treatment of abortion has become more rational and successful. Affected subjects are disinfected, strictly isolated, fed, and sold off. The bulls are dressed with corrosive sublimate solution, and the tail, head, vulva, and hindquarters of the cows in calf are -also repeatedly washed with sublimates or other effective solutions in order to destroy any organisms that may have lodged upon them. A good deal, however, has still to be learned regarding the hfe history of the organism. Competent (investigations should throw light upon Its origin and explain how the first case in an outbreak arises. TiENMOHB. —Colt with worms: Tepid soap and water injections with a little carbolic (1 per cent.) added should bo useful for removing these worms. Give a little powdered sulphate of (iron ana pulverised gentian root mixed In her food night and morning, half a teaspoonful of each. Continue the powders for 10 days or a fortnight. A piece or rocksalt should also lie pub in the manger. Farmer writes: —“ I have a draught horse which is to ell appearances perfectly sound —hoofs good, legs sound, and no heat oswelling anywhere; but of late he is always resting one front leg. and at intervals lie becomes very lame, especially in cold or wet weather. I use him frequently in the shafts of the dray. What is the trouble?” We would advise you to have an experienced professional man to examine the horse, as if neglected it may develop into incurahlo lameness;.
