VETERINARY SCIENCE AND PRACTICE. 1129 



Circular letter? of iiKiuiry .^eiit to sheep men elicited replies which indicate that 

 sheep are ijnite regularly dijipeil for destroying these pests, but not always at the 

 ])roi)er season of the year. A complaint has been made that the numbers of sheep 

 maggot-flies are somewhat increased as a result of the practice of hanging decaying 

 meat in forest areas as a breeding place for the maggots which are eaten Ijy grouse. 

 In controlling this pest the author recommends cleanliness, dipping, and hand 

 treatment with kerosene or substances with offensive odor. 



Prophylaxis of foot-and-mouth, disease, P. Labully {Ann. Soc. Agr., Loirt, 2. 

 ser., 23 (190.3), X<i. 2, jij). 1 .'■'>, 126). — Brief notes are given on the production of 

 immurity toward foot-and-mouth disease by means of serum indculations. Such 

 immunity, however, has been found to be merely temporary. 



Acute ulcerative inflammation of the cornea or eye-ball, in cattle, sheep, 

 and goats, D. IIitcheox (Aijv. Jour. Cape Good Hope, 24 {i:>04), Xo. 5, pp. 021- 

 624). — The symptoms and pathological anatomy of this disease are briefly described. 

 In controlling the disease it is recommended that affected animals be isolated and 

 that the eyes be treated with a weak antiseptic solution, such as corrosive sublimate. 



Joint ill {Jour. Bd. Agr. [London^, 11 {1904), i^'o. 2, j^P- 110-114)-— This disease 

 affects lambs, calves, and colts. The source of infection is through the umbilical 

 cord at the time of birth. Detailed directions are given regarding the control < if the 

 disease in lambs by means of proper disinfectant measures. 



Loco, N. S. Mayo {Indu.<tricdi.<^i, 30 {1904), ^o. 30, pp. 473-475). — The symptoms 

 of loco disease attributed to eating Axiragalus moUissimus are described. As a result 

 of oliservations and experiments on this disease the author believes that the disease 

 is a result of malnutrition or starvation, exaggerated perhaps by some injurious sub- 

 stance in the loco weeil. 



The composition of Zygadenus venenosus and the pharmacological action 

 of its active principle, X. Vejux-Tyrode {Jour. Med. Research, 11 {1904), Xo. 2, 

 pp. 399-402) . — In a study of the bulbs of this plant obtained from ^Montana the author 

 found a wax-like body, a crystalline neutral substance, an oil, a gum, and two resins. 

 All of these substances are inactive except the resins. From one of the resins a basic 

 body and an acid called zygadinic acid were isolated. The basic body is denominated 

 zygadinein and was found in animal experiments to be the active principle. In 

 minute doses in experimental animals, including guinea pigs, rabbits, and dogs, it pro- 

 duced marked salivation, staggering, and respiratory paralysis followed by death, in 

 some cases within a few minutes, but usually within a few hours. 



Osteomalacia and paralysis, D. Hutcheox {Agr. Jour. Cape Good Hope, 24 

 ( 1904 ) , Xo. 4, PP- 479-4S7 ) . — This disea*-e is believed to be of dietetic origin. It occurs 

 over a large area of Cape Colony, but is most prevalent on the eastern coast. It affects 

 cattle, sheep, goats, and horses, but rarely assumes the paralytic form in horses. Ani- 

 mals affected with the disease manifest intense desire for bones and all kinds of 

 animal-food materials. Notes are given on the pathological anatonn- of the disease. 

 In controlling this disease the obvious suggestion is made of adding a daily allowance 

 of bone meal, bone ash, or similar material to the ration. 



Observations on epizootic outbreaks of tape-worms in sheep in the Govern- 

 ment of Moscow, M. L. Blumenfeli) {ArrJt. ]'et. Xauk, St. Petershnrg, 34 {1904), 

 No. 1, pp. 29-38). — An ac(;ount is presented of the extent of infestation of sheep in 

 the Government of Moscow by Taenia e-vpanm. The percentage of infestation in dif- 

 ferent part< of the government is shown in a tabular form. The author concludes 

 that considerable pathogenic action is exercised by the presence of tapeworms in 

 sheep and that these pests cause a great loss to the sheep industry. 



The development of Herpetomonas, S. Prowazek {Arh. K. Gesundheitsamte, 20 

 {1904), Xo. 3, pp. 440-4-52, Jigs. 7). — The literature of this suljject is criticalh- discussed 

 in connection with l)ihliographical references. Particular attention is given to iletails 

 in the life history an<l development of Herjietoinonos musae-domestica'. The different
