VETERINARY SCIENCE AND PRACTICE. 



Glanders, W. L. Williams [Montana Sta. Bid. 4, pp. 67-113, pis. 7). — 

 This is a general discussion on the subject in popular form. Among 

 the topics treated are the pathology, symptoms, and diagnosis of glan- 

 ders; strangles, pink eye, acute nasal catarrh, infectious or epizootic 

 catarrhal fever, chronic nasal catarrh, diseases of the facial sinuses, 

 diseased teeth, and nostril tumors, which have sometimes been con- 

 fused with glanders. The only safe method of diagnosis is the use of 

 mallein. 



"Although most modern investigators admit the curability of some cases of glan- 

 ders, these recoveries are confessedly few and the treatment of the malady, whether 

 by medicines or mallein, is yet purely experimental, unworthy of confidence from a 

 practical standpoint, yet pointing hopefully toward reliable treatment in the near 

 future. Apparent recoveries from glanders are unfortunately too often apparent 

 only, and serve to continue the spread of the disease." 



Experimental trichinosis in Spermophilus 13-lineatus, G. W. 



Stiles ( Vet. Mag., 1894, pp. 737, 728; Centbl. BaU. und Par., 16 {1894), 

 No. 19, pp. 777, 778). — The disease trichinosis was given experimentally 

 to spermophiles, but the author does not believe that these animals 

 are of any practical importance in transmitting the disease to hogs. —

Discussion of the coccidian origin of cancer, Fabre-Domergue 



{Ann. Micrographie, 1892, pp. 49-67, 97-110, 145-164, 221-236, 579-587, 

 603-614, figs. 27). — The author's conclusions may be summarized as fol- 

 lows: (1) The parasite theory of cancer, originating in the writings of 

 Pfeiflfer, Darier, Wickham, and d'Albarran, rests upon observations 

 which have no connection with one another and no analogy; (2) the 

 objects described as Sporosoa have only certain morphological resem- 

 blances to these animals, but do not possess coccidian characters; (3) 

 all the pseudococcidia as yet described are connected by insensible 

 gradations with the neoplastic cell, from which they originate by 

 degeneration; (4) epithelial cancers of animals, really homologous to 

 those of man, are also not parasitic; (5) in attempting to demonstrate 

 the necessity of a parasitic origin by comparing epithelial cancers with 

 galls of vegetables and infectious neoplasms of animals one fails to 

 recognize the very nature or essence of cancer and compares conditions 

 which are not comparable. — c. w. stiles. 



Notes on parasites, C. W. Stiles and A. Hassall ( Vet. Mag., 1894, 

 pp. 729-741, figs. 11). — A new species of intestinal fiuJce [Distomum tricolor) 

 in the cotton-tail rabbit {Lepus sylvaticus Bachman) and in the Northern 

 hare {L. americanus Erxleben). This species is found to be common in 

 Maryland, the District of Columbia, and Virginia; it stands midway 

 between the genera Mesogonimus and Urogonimus, and the authors are 

 doubtful as to the validity of these two genera.
