added to the food. A peculiar case of intestinal infestation in a horse is reported. 

 The larvre of botflies were found attached in considerable numbers to Ascaris mega- 

 locephala and tapeworms in the intestines of the horse. 



Treatment for worms in domestic animals, D. Hutcheon (Agr. Jour. Cape 

 Good Hope, 27 {1905), No. 5, pp. 589-6 1 4, figs. £0) .—Particular attention is given to 

 treatment of domesticated animals for tapeworms, roundworms in horses, and 

 stomach worms of sheep. 



Sulphate of copper is said to be one of the longest used and most effective remedies 

 for roundworms in horses. It also gives good results in the treatment of stomach 

 worms in sheep and tapeworms in calves, lambs, and kids. During experiments in 

 drenching animals with a solution of sulphate of copper, it was found that goats were 

 more resistant to this drug than sheep. Goats were given as much as 40 grains sul- 

 phate of copper and 4 oz. of water without harm, no inflammation being caused in 

 the mucous membrane of the stomach. In the preliminary experiments with sul- 

 phate of copper in treating lambs, however, numerous cases of the poisonous effects 

 of this substance were seen and many deaths were caused. 



After further experimentation it was decided that copper sulphate to be used for 

 such work should be of standard purity of a uniform dark blue color. It appears 

 that a fast of more than 30 hours renders sheep more susceptible to the influence of 

 copper sulphate than they otherwise would be. The author recommends that 1 lb. 

 of copper sulphate be dissolved in 10 gal. of water, and that from this solution lh, 3, 

 3 h, 4, and 5 oz., respectively, be fed to lambs 3, 6, 9, 12, and 18 months old. 



Numerous experiments were carried out in treating ostriches for infestation with 

 Srtongylus douglassii. As a result of these experiments it was found that a prelimi- 

 nary dose of kerosene oil tends to remove gastric mucus caused by the presence of 

 parasitic worms. The parasites are then more directly exposed to the action of car- 

 bolic acid and turpentine, which are recommended in destroying these worms. The 

 method of procedure recommended by the author is as follows: After fasting 18 hours 

 give 12 oz. of kerosene and an equal quantity of milk to adult birds. After 2 or 3 days 

 allow the birds to fast again for 18 hours, after which they are to be given 4 dm. car- 

 bolic acid and 12 dm. of turpentine in 10 oz. of water.

 Dept. Agr., Bur. Anim. Indus. Rpt. 1904, pp. 268-285, figs. 31).— In this article the 

 author presents complete descriptions of all species of tapeworms known to occur in 

 chickens and turkeys in the United States. A key is also given to assist in their iden- 

 tification and brief notes are presented on the life history of the tapeworm and means 

 of eradicating them.
