tuljercle liacilli introduced into the lymph eavity of a frog are carried from this posi- 

 tion into the internal organs and may be found in such locatic^ns for weeks or even 

 months. At the point of injection small granulating tuljercles are not infrequently 

 developed. Tubercle bacilli which have remained for weeks in the body of a frog 

 do not produce tubercles when inoculated into guinea pigs. 



Parturient apoplexy. A discussion of milk fever, W. A. Thomas {Jour. 

 Contp. Med. and Vet. Arch., 21 {1900), No. 11, j^p. 671-675).— In order to secure 

 information regarding the methods of treatment of practicing veterinarians and their 

 success with cases of parturient apoplexy, the author sent out a circular letter of 

 inquiry to the practicing veterinarians of Nebraska, from whom 11 replies were 

 received. Of the veterinarians who replied to the circular 9 had given medicine by 

 way of the mouth and 3 had adopted the Schmidt treatment. The success of treat- 

 ment was not striking in any case. The author objects to the use of the term par- 

 turient paresis and inclines to the belief that the primary lesions of the disease are 

 in the brain. 



Tumor formations in certain of the domestic animals, .J. A. Gilruth ( Veter- 

 inarian, 73 {1900), No. 870, pp. 291-301, figs. 6). — Degenerate and calcified hydatids 

 were present in the lungs and liver of a vast majority of cattle and sheep inspected 

 in the abattoirs of New Zealand. Notes are given for the purpose of reaching a dif- 

 ferential diagnosis between such nodules and those of tuberculosis. A similar dis- 

 cussion is given of nodules of the peritoneal surface of the intestines, calcareous 

 nodules in the flanks of sheep, epithelioma, and granuloma. 



Swine fever, J. A. Gilruth {Veterinarian, 73 {1900) , No. 872, pp. 419-439, fig». 4).— 

 From a series of observations and experiments made by the author it is concluded 

 that pulmonary and pleural lesions frequently occur along with or independently of 

 the so-called characteristic intestinal lesions of swine fever. The results obtained 

 indicate that it is doubtful whether hog cholera and swine plague are 2 distinct 

 diseases. 



Mallein in the treatment of glanders, J. McCall ( Veterinarian, 73 {1900), No. 

 870, pp. 383-387). — Detailed notes are given on 4 horses injected with mallein. 

 Cultures made from tubercles found on post-mortem examination gave negative results, 

 while the reaction to mallein was well marked, and the usual anatomical lesions of 

 glanders were found. 



The nature of "horse sickness," Rickmaxn {Berlin. TieriirzH. Wckn.schr., 1900, 

 No. 29, pp. 337, 338). — The author inoculated himself and also a horse with 1 cc. of 

 virulent blood from a case of this disease. After 11 days the horse died of typical 

 symptoms of the disease, while the author was entirely unaffected by the operation, 

 although he was susceptible to malaria. The author believes that although this dis- 

 ease is very .-similar to malaria it is not identical with it. 



Diseases caused by horse worms, and their treatment, F. V. Theobald {Jour. 

 Southeast Agr. Col. Wge, 1900, No. 9, pp. 49-66, figs. 7). — Biological'and economic 

 notes are given on the common species of tapeworms and nematodes, which are found 

 parasitic in the horse. 



Dourine and its pathogenic organism, G. Schneider and M. Blffard {Eec. 

 Med. Vet., Paris, 8. ser., 7 {1900), No. 3, pj). 81-105, figs. 20).— The authors made 

 extended investigations on dourine in horses with regard to methods of prevention, 

 diagnosis, and treatment, and a special study of the etiology of the disease. The 

 pathogenic organism is considered to be a species of Trypanosoma. The authors 

 were able to produce the disease experimentally in horses, dogs, rabbits, rats, mice, and 

 the jackass. It was found that the organism could be transmitted l)y a hypodermic 

 injection, by contact with the mucous membrane of the vagina, and by inoculation 

 under the cerebral membranes. 



Detailed notes are given on the period of incubation of the disease in different
