" While the eggs may be numerous in the nodule, traces of the Distoma have 

 never been discovered. The intermediary host of D.- lanccolatum is thought to 

 be a mollusk of the genus Planorbis. Embryos of the parasite and the adult 

 worm may be found in water and pass into tlie stomach of the horse. From 

 the stomach it passes to the beginning of the intestine, gains the duct and makes 

 its way to the biliai-y ducts where it sets up the changes of ordinary inflamma- 

 tion. As it does not find the conditions in the liver favorable, it deposits eggs, 

 leaves tlie liver for the intestine, and passes out with the feces." 



Although the authors have never been able to demonstrate the parasites in 

 the nodule, they do not deny the possibility of their becoming at times the 

 center of a nodule. 



Some observations on equine piroplasmosis, A. Pricolo {Rev. Gen. M6d. 

 Vet., 13 (1909), No. l-'i6, pp. 60-64; «&*"• in Jour. Trop. Vet. 8ci., 4 {1909), No. 3, 

 p. 1/55). — This is a contribution from the military laboratory of veterinary 

 bacteriology at Rome. 



The disease is said to be generally disseminated over Italy, certain centers 

 of permanent infection being iiresent from which it has a tendency to extend. 

 It also appears in Rome in the hot season and the autlior has microscopically 

 diagnosed it in blood from Nettuno, Civita Vecchia, Mcenza, Persano, Bologna, 

 and Chieta. The most successful treatment so far adopted consists in the sup- 

 pression of all drugs and allowing as much pure water as the animals will 

 drink. 



Rabies in very young dogs, P. Remlinger {Rci\ Gen. Med. Vet., 12 (1908), 

 No. 143, pp. 617-62.',; Compt. Rend. 80c. Biol. [Paris], 65 (190S), No. 3J,, pp. 

 508, 509; Jour. Trop. Vet. Sci., -', (1909), No. 3, pp. //S.5-//90).— By the passage 

 of the rabid virus through a young dog its virulence is increased and under 

 similar circumstances this renders it more dangerous to man than that of an 

 adult dog. Of 9 small dogs inoculated with small doses of street virus 7 con- 

 tracted the disease. The percentage is much higher than that obtained with 

 adult dogs under similar conditions. In the majority of observations the virus 

 inoculated beneath the skin of the dog demonstrated an incubation period 

 analogous to that which would have been shown had it been inoculated sub- 

 durally in the ral>bit. From a clinical point of view rabies ill young dogs has 

 no great difference from that in older dogs and is not more difficult to diagnose. 



Microsporosis of the dog", Sabouraud, Suis, and Suffran (Rev. Vet. [Tou- 

 louse], ;?// (1909), Nos. 1, pp. 1-1.',; 2, pp. 73-8J,; 3, pp. 131-11,9, figs. J,).— The 

 authors here report at some length the results of studies made of 15 cases of 

 ringworm. The Microsportim lanostim is said to occur very frequently in dogs 

 in the region about Toulouse. 



Diseases of the dog and tlieir treatment, G. Mxjller and A. Glass (Phila- 

 delphia, [1908], 2. ed., rev. and enl., pp. XVII +.',19, 2)ls. 10, figs. 93).— A second 

 revised and enlarged edition of this work, in which the articles on distemper, 

 rabies, and tuberculosis have been rewritten. 



Hyoscine-morphine-cactin the most desirable anesthetic for dogs, D. M. 

 Campbell (Amer. Vet. Rev., 35 (1909), No. 5, pp. 568-570). — ^A compound of 

 hyoscine 1/100 grain, morphin 1/4 grain, and cactin 1/67 grain is considered 

 to be the safest anesthetic for dogs. The greatest advantage noted from its 

 use is the quiet it induces after operation. 



Natural infection of the guinea pig with Malta fever, C. Nicolle and E. 

 Conseil (Compt. Rend. Soe. Biol. [Paris], 66 (1909), No. 12, pp. 503-505; ahs. 

 in Jour. Trop. Vet. Sci., J, (1909), No. 3, p. -)S5).— While it is not easy to infect 

 a guinea pig with Malta fever, recent observations show that it may become 

 naturally infected. In 5 guinea pigs purchased from a Maltese goat keeper, 

 2 were found to have an agglutinating power of 300 and from 1 of these the
