VETERINARY SCIENCE AND PRACTICE. 93 



curative power of the Kimberly serum seems high. Doses of from 5 to 

 10 cc. of diphtheria serum are said to cure, but a dose of 10 cc. of 

 the Kimberly serum has cured animals of 300 kg. weight when injected 

 two days after infection. Calculated in weight, 1 gm. of the Kimberly 

 serum is equal to 36,200 kg. of animal; or, considering only the chemi- 

 cal substances, the author gives the curative ratio analogously to that 

 of the diphtheria serum of Brieger Boer as 1 to 360,000,000. 



How different the Kimberly serum is from the normal may be seen 

 from the fact that 1,000 cc. of the latter will not protect an animal 

 when injected twenty-four hours after the injection of i cc. of virulent 

 blood. Whether the serum is antitoxic or microbicidal remains to be 

 decided, though the authors suppose it may be microbicidal. 



The sheep fluke, X. A. Cobb {Dept. Agr. yea- South Wales, Misc. 

 Pub. 167, pp. 32, Jigs. 30, pi. 1). — In this pamphlet there is given a pop- 

 ular account of the sheep tluke as it exists under Australian conditions, 

 together with suggestions as to the methods of dealing with it. 



In a study of the liie history of the sheep fluke the cercaria of the 

 latter were found, after long search, in the snail (Bulimus brazieri), a 

 species entirely different from that serving as the intermediate host of 

 the sheep fluke in Europe. 



The author's remedial recommendations are all of a preventive sort. 

 The burning of pasture lauds it is thought may do some good, but the 

 best methods are those of draining swampy lands, fencing them off so 

 as to keep sheep away from them, or the formation of ditches or reser- 

 voirs for the collection of drinking water in such a way that it can not 

 be contaminated by dung, and so become infected with the free swim- 

 ming larv;c of the fluke. The rotation of stock upon pasture lands is 

 also among the remedial measures recommended; that suggested as 

 the best is sheep, horses, bullocks, horses, sheep. " 



A few notes are given on the Australian snail-eating birds, viz, the 

 common mud lark, magpie lark or peewee ( Grallina picata), pied grallina 

 {Grallina a ustralis), and the white fronted heron (Ardewnovce-hollandice). 



Contribution to the natural history of Trichina spiralis, J. Y. 

 Graham (Arch. Mikros. Anat., 50 {1897), No. 2, pp. 214-275, pis. 3; dbs. in 

 Zool. Centbl, 5 {1897), Xo. 2, pp. 47, 48).— The author substantiates what 

 has been observed several times heretofore, that the female deposits the 

 brood not in the lumen of the intestine, but under the epithelium of the 

 intestinal mucous membrane. The males are also found in the latter 

 place. The young worms reach the lymph vessels and lymph glands, 

 and then the ductus thoracicus of the blood vessels. When they reach 

 the striated muscles they leave the blood capillaries and enter the 

 muscle tissue. The penetration of the sarcolemma and the wandering 

 about inside the muscle fibers, observed heretofore, is confirmed. If 

 the trichina reach the cardiac muscle they perish. Their fate is the 

 same also if they get into the pericardium or peritoneum. The author 

 does not believe in the poisonous action of the worms. Two small
