VETERINARY MEDICINE. 83 



lu addition to these forms small, rounded, generally motionless forms were 

 met with in which the typical nucleus and blocks of the first form were seen. 

 Infection is probably only effected by food contaminated by feces containing 

 cysts of the parasite. 



Trypanosoma ingens n. sp., D. Bruce et al. (Proa. Roy. Soc. [London], 

 Ser. B, 81 (WOD), Xo. B 5/,9, pp. 323, 32.',, pi. i).— This species was found in 

 the blood of a reed buck, a bush buck, and an ox at Xamukekera. Uganda. 



Experiments and observations on the development of Trypanosoma lewisi 

 in Haematopinus spinulosus, F. S. H. Baldrey {Arch. Protistenlc, 15 {1909), 

 Xo. 3, pp. 32G-332, figs. 2; abs. in Sleeping Sickness Bur. [London], Bui. 9, pp. 

 323, 32Jf). — The author thinks that the mechanical transmission of T. lewisi by 

 lice is an exception. 



Toxin formation in trypanosomiasis {Sleeping Sickness Bur. [London], 

 Bui. .'', pp. ,{.>i)-.i2S). — A brief review of the literature on the subject. 



Further results of the experimental treatment of trypanosomiasis; a 

 progress report to a committee of the Royal Society, II. G. Plimmer and 

 W. B. Fry (/'roc. Roy. Soe. [London], Ser. B, HI {1909), No. B 5J,9, pp. 35.',- 

 371). — This is a continuation of experiments with the same strains of surra as 

 previously noted (E. S. R., 20, p. 985). 



Rats were treated with antimony and several of its compounds, with quassia, 

 and with arsenophenylglycin. Dogs used in experiments with antimony were 

 found to be extremely susceptible both to the disease and to antimony. 



Further experiments upon the drug treatment of canine piroplasmosis, 

 G. H. F. NUTTALL and S. IIadwen {I'arnsitology. 2 (1909), No. 3, pp. 229-235).— 

 A continuation of work previously noted (E. S. R., 21, p. 488). 



" Trypanblau injected subcutaneously into dogs a day before or a day after 

 they have been inoculated with blood containing Piroplasma canis effectually 

 prevents the development of piroplasmosis by destroying the parasites at the 

 onset of infection. Trypanblau given by the mouth is ineffective, since it exerts 

 no apparent influence either upon the parasite or upon the course of the disease. 

 Tryparosan, when injected subcutaneously or when given by the mouth, has no 

 effect upon the parasite and is ineffective as a remedy against piroplasmosis in 

 the dog." 



The drug treatment of piroplasmosis in cattle, G. H. F. Nuttall and S. 

 Hadwen {Parasitology, 2 {1909), Xo. 3, pp. 236-266, charts 7).—" Trypanblau 

 promises to be an efficient remedy for bovine piroplasmosis, since it exerts a 

 direct and obvious effect upon the parasites. The effect of the drug upon 

 Piroplasma hovis is similar to that which it produces upon the canine parasite. 

 As in canine piroplasmosis, the disappearance of the parasites from the blood 

 may be temporary. The parasites also disappear and reappear in small num- 

 bers (after 2 to 11 days) in animals undergoing natural recovery. In 3 treated 

 animals the parasites reappeared in exceedingly small numbers after .5 to 6 

 days; in 2 they had not reappeared after 16 and 18 days, respectively. The 

 animals show no symptoms and progress toward recovery. Although doses of 

 150 to 200 cc. of a saturated watery solution of the dye were used, it is probable 

 that smaller doses will prove efficient. The drug appears to produce no ill 

 effects upon cattle." 



The discovery of a remedy for malignant jaundice in the dog and for 

 redwater in cattle, G. H. F. Nuttall and S. Hadwen {Proc. Roy. Soc. [Lon- 

 don], Ser. B, 81 {1909), Xo. B 5^9, pp. 3J,8-350).—'SloTe detailed accounts are 

 noted above. 



Tests concerning tubercle bacilli in the circulating blood, E. C. Schroedeb 

 and W. E. Cotton {U. S. Dept. Agr., Bur. Anim. Indus. Bui. 116, pp. 23).— In- 

 vestigations conducted in order to determine whether tubercle bacilli occur In 

 the circulating blood are here reported in detail.
