T he Veterinary J ow·ncll
Kaufmann (Finlay Dun) states 6 ounces as a poisonous dose for horses or cattle. A small two-year-old heifer was given 8 ounces by a shopkeeper, serving it in mistake for cattle salts, and, on finding out the error soon after she"had received it, the owner came in for advice. He reported that she appeared all right when he left home. I advised him to g ive her a tumblerful of whi sky, and repeat it in an hour if necessary. She never howed ·any ill-effects, and I do not think she had any benefit from the whisky, as about four hours elapsed before she r eceived it. POISONING BY HORSETAIL (EQUISETUM A RVE1YSE). BY R. H U DSON, F.R.C.V.S., R elford.
Synonyms : Scouring-rush, Shavegrass, Marestail, Bottlebrush . Characters: Stem-jointed , branching at joints, arranged like bottle brush. Cattle were affected, and th ey were grazing on clover, the field being rather bare except where the plant grew. In that part a d epression formed across the field , and in it the plant was abundant. Th e symptoms shown were diarrhcea, weakness of the hindquarters, and slightly " tucked up" appearance. I o animals died, and on b eing r emoved to another pasture they soon recovered. I have only seen the plant on clover on this occasion, and think it probable the spores came with the clover seed, which might have been foreign. No doubt the greater moisture in the lower part of the field favoured its growth there . POISONING IN CALVES BY NASCENT HYDRO CYAN IC ACID EVOLVED BY CAKE IN SOLUTI ON. BY G. T . D U NE, F.R.C.V.S ., P rofessor of Therapeu tics, the Vete rinary College , his '• F ree State.
IT is now of course a well established fact that certain very valuable food-stuffs contain substances which under suitable cond itions will generate hydrocyanic acid in varying quantities, these amounts being sometim es sufficiently large as to set up seriou s illness in farm stock. Amongst these foods are millet, J ava beans, linseed, etc ., and it is in connection with linseed that I have noticed the toxic action sometimes rather well marked ; in fact , I am almost inclined to believe that the freshly genera ted acid is more powerful than if administered as the B.P. solution.
