made to determine the value of ateam disinfection of stables in which the disease 

 occurred. The steam was applied in as careful and thorough a manner as possible. 

 As a result of these experiments it is concluded that steam is an efficient disinfectant, 

 provided it is applied at a temperature of not lower than 100° C. In order to pro- 

 duce that temxjerature, however, in large stables the ordinary api)aratus in common 

 use is insufficient, and it is considered that this method nuist therefore be aVjandoned 

 in the disinfection of stables. 



Observations on the chicken plague ■which ■was introduced into Oldenberg- 

 from the Bruns-wick Chicken Exposition, L. (iuKVE [Dent. Ticri'irzll. WchnscJir., 

 9 [1901), No. ,37, pp. 373-376). — Post-mortem examination of fowls dead with this 

 disease showed no pathological changes in the stomach. The blood vessels of the 

 intestines were somewhat injected. Small red spots were observed on the heart and 

 peritoneum. The bacillus of chicken cholera could not be demonstrated in the 

 blood or other organs. Inoculation experiments with blood from the heart of a hen 

 dead with the disease produced no infection in pigeons or white mice. Feeding 

 experiments with infecteil material, however, caused the develojiment of the disease 

 in sparrows and pigeons. Wliile the identity of the disease is not deiinitely deter- 

 mined, it is reconnnended that the S'ame precautions be ol)served as are usually 

 recommended in outbreaks of chicken cholera. 



Brief statistics, ]\I. Strebel {Schweiz. Arcli. Tlerlt., 43 {1901), No. 5, pp. 210- 

 220). — The author presents in a tabular form a list of the diseases which were treated 

 in his practice during the past year. The number of cases of each disease are given 

 and the animals affected. Brief mention is made of some of the more important 

 diseases which are discussed by the author in the l)0(ly of the article. Verminous 

 bronchitis was observed in 43 calves and young cattle varying in age from 8 to 16 

 months. The animals were grazing on wet pastures. In the treatment of this dis- 

 ease the best results were oljtained by causing the animals to inhale a mixture of 4 

 parts of ether and 1 part oil of turpentine. This mixture was administered 3 times 

 per day, a spoonful being poured into the nasal cavity. The author makes a report 

 on 9 cases of actinomycosis, 6 of which were localized in the tongue and 3 in the 

 thyroid and laryngeal glands. 



Report of the State board of health, H. ^Mitchell {New Jermi State Bd. Agr. 

 Rpt. 1901, pp. 229-234). — Brief notes are given on the cases of infectious diseases
