of tricliinosis, the biology of TrichincUa spiralis, its occurrence in the body, the 

 effect of its presence upon the components of the blood, its relation to bacterial 

 infection, occurrence in mammals, etc. 



An extensive bibliography and author and subject indexes complete the work. 



Anthrax and helminthiasis in the horse, Chakon, Valade, and Texieb 

 (Rec. Med. Vet., S7 {1910), No. 15, pp. 505-500). — A description of a case in an 

 artillery horse, in which ascarids and anthrax bacilli were present at the same 

 time. 



The behavior toward saponin of the blood (plasma, serum, and erythro- 

 cytes) from a horse having pernicious anemia, E. Abderhalden and W. Fbei 

 (Arch. Wiss. u. Pralct. Tierheilk., 36 {1910), No. Jf-5, pp. ^23-431, charts 2).— 

 The authors sought to determine whether the serum from animals having per- 

 nicious anemia and the serum of normal animals behave alike, and whether 

 the blood and the erythrocytes alone react in the same manner toward saponin. 



The results show that larger amounts of saponin were necessary to bring 

 about hemolysis in the blood in pernicious anemia than in normal blood. Be- 

 tween the washed erythrocytes from normal animals and animals having per- 

 nicious anemia no difference in regard to hemolysis could be noted. Inhibition 

 was greater with the serum of pernicious anemia than with normal serum. 



Osteoporosis affecting horses in Ceylon, G. W. Sturgess (Vet. Jour., 66 

 (1910), No. .'f25, pp. 682-685). — The author states that cases of this affection 

 probably occur in every part of Ceylon. 



Strangles (Adenitis equorum).— Vaccination tests with Schreiber's lymph, 

 A. Zokneb (Arch. Wiss. u. Pralct. Tierheilk., 36 (1910), No. Ji-5, pp. 532-582, 

 charts 12). — Schreiber's lymph is a maceration extract obtained from 3 strains 

 of streptococci taken from the affected glands. From his work the author con- 

 cludes that the lymph is a valuable therapeutic agent, and that the perfectly 

 clear lymph can be employed intravenously or subcutaneously and without 

 danger. Its injection has a decidedly beneficial constitutional effect, and when 

 employed early it has a tendency to prevent metastasis and to keep the condition 

 localized. The lymph can also be utilized for actively immunizing sound horses 

 and foals. The author further found that the lymph does not stimulate an 

 aggresin (Bail) action. 



The cure of surra in horses by the administration of arsenic, J. D. E. 

 Holmes (Parasitology, 3 (1910), No. 3, pp. 288-306, pis. 6).— "The results 

 herein recorded are further evidence that arsenic is a specific for surra in 

 horses; that a permanent cure is effected, and not merely a temporary toler- 

 ance of the disease; that the treatment is simple, and that by careful dosage 

 70 per cent and upward of surra cases, even when contracted spontaneously 

 and in the last stage, can be cured. Arsenic is best administered in form of 

 arsenious acid, in bolus or in solution. Atoxyl is a convenient form of giving 

 arsenic hypodermically." 



The methods of dosage which have been found successful and the principles 

 upon which the success of the arsenic treatment depends are described. 



The preventive dose of tetanus antitoxin for the horse: Its relation to the 

 American unit, A. P. Hitchens (Amer. Vet. Rev., 37 (1910), No. 5, pp. 597- 

 610).— The object of this paper was to present proof (1) that in the customary 

 doses employed tetanus antitoxin is a valuable preventive agent; and (2) to 

 ascertain the efficient dose expressed in American units. From his work the 

 author concludes that " tetanus antitoxin as a preventive of tetanus in the horse 

 is as nearly perfect as anything in biology can be. A very small quantity of 

 tetanus antitoxin is suflicient to protect a horse against an ordinary infection. 

 Clinical experience proves a dose of 500 units to be amply sufficient for prac- 

 tically all cases."
