VETERINARY MEDICINE. 



Third annual report of the commissioner of animal industry for the year 

 ended November 30, 1914, F. F. Walker {Ann. Rpt. Comr. Anini. Indus. 

 [Mass.], 3 {1914), PP- 38). — This reports upon the occurrence of and control 

 work with diseases of animals during the year. 



Fourth annual report of the commissioner of animal industry for the year 

 ended November 30, 1915, L. H. Howabd {Ann. Rpt. Comr. Anim. Inaus. 

 [Mass.], 4 {1915), pp. 62). — The usual annual report. 



[Report of the] department of veterinary science and bacteriology, W. B. 

 Mack {Nevada Sta. Rpt. 1915, pp. 1^-19). — In inoculation experiments con- 

 ducted with equine anemia in an effort to determine whether or not it is 

 transmissible conflicting and inconclusive results were obtained. The thera- 

 peutic work also gave negative results. 



In a flock of 22 fowls in which an outbreak of chicken cholera occurred the 

 disease was promptly checked through the injection of killed cultures of 

 chicken cholera bacilli. In a flock of 63 birds injected twice, eight days apart, 

 the disease was also checked, 19 having died between the treatments. Refer- 

 ence is made to work with contagious epithelioma in chickens, bulletins on 

 which have been previously noted (E. S. R., 34, p. 189; 35, p. 885). 



An acute disease of cattle, usually fatal, occurs in certain valleys close to the 

 Sierra Nevada Mountains, extending along these mountains for a distance of 

 about 150 miles. Investigations conducted have led to the conclusion that it is 

 probably hemorrhagic septicemia. 



The outbreak of rabies in neighboring States spread into northern Nevada 

 in April, 1915. Brief reference is made to fatty degeneration of the muscles in 

 suckling lambs in a small band of pure-bred Hampshire sheep. 



A study of soy bean hay, A. C. Whittiek {Delaware Sta. Bui. 112 {1916), 

 pp. S-18). — During the course of a feeding period of sheep and cattle in which 

 soy-bean hay was used as a roughage much trouble was experienced in that the 

 young animals were delivered in a weak and feeble condition which made their 

 raising difficult, if at all possible. The trouble was abated by substituting corn 

 fodder, hay, and silage for the soy-bean hay. This condition was deemed prob- 

 ably due to some constituent of the soy-bean hay, and a chemical study of the 

 material was therefore made. 



The regular feeding-stuff analysis reported does not differ in any respect 

 from those usually reported, except in the percentage of nitrogen-free extract, 

 which was somewhat higher. On analysis the ash was found to have the fol- 

 lowing percentage composition: Silica, 2.3; sulphur (from ash), 0.23; sulphur 

 (wet oxidation), 0.25; sulphur soluble in 2 per cent hydrochloric acid, 0.15; 

 phosphorus (total), 0.37; phosphorus (inorganic), 0.08; calcium, 1.21; mag- 

 nesium, 0.48 ; potassium, 2.24 ; iron, 0.14 ; and aluminum, 0.1. The various forms 

 of carbohydrate and nitrogenous materials present were also determined. 



Examination of ligroin, ether, chloroform, and alcohol extracts showed vola- 

 tile oils, glucosids, and alkaloids to be absent, thus excluding these substances 

 as possible toxic agents of the hay. 



Hydrolyses of the hay were made with water, 1, 5, 10, and 25 per cent sul- 

 phuric acid, 2 per cent sodium hydroxid, and 20 per cent hydrochloric acid, the 

 last-named being found the best hydrolytic agent. A determination of the 

 nitrogen distribution of the hydrolyzed material according to the Van Slyke
