The diagnostic value of agglutination in glanders, .1. S< FTNURER | Centbl. Unit. 

 [etc.] i. 'Abt., Orig., 39 I 1905), No. /. pp. 180 181 I. The author describes in some 

 detail the technique of the method including the taking and sending of blood samples, 

 repetition of this process, the preparation of the tests, and the judgmenl of results. 

 It appears thai between the 2 groups of decidedlj positive and negative results some 

 uncertain cases will appear which require a repetition of the test. 



The unity of dourine, < h E. Schneider and M. Buffard [Ann. Inst. Pasteur, 19 

 (1905), No. 11, pp. 716 717). Attention is called to the difficulty of demonstrating 

 the blood parasite in cases of dourine. The author was able, however, t<> determine 

 the presence of Trypanosoma rougeti as the cause of dourine in France. 



Studies on Trypanosoma duttoni, Tin roux (Ann. Inst. Pasteur, 19 (1905 . Vb. 

 9, pp. 564-572, pi. /'. This blood parasite was found in the blood of house mice, 

 and notes are given on its appearance and on successful methods of cultivating 

 it. The various forms which it assumes in artificial cultures are also noted. 

 The organism may be reinoculated from one specimen to another of house mice and 

 also to other specie s of the same genus, hats and guinea pigs, however, seem to be 



refractory. The blood of animals recovered from infection < tains no agglutinin 



toward Trypanosoma duttoni. 



Trypanosomes in the blood of inoculated animals, A. Nissle (Arch. Hyg., 

 53 I 1905 I, No. 3, pp. 181 204 I. The observations reported in this article were made 

 on laboratory animals inoculated with Trypanosoma brucei, '/'. equinum, and T. lewisii. 

 hats, white mice, and guinea pigs were the chief experimental animals employed. 

 The author describes in some detail the morphological changes undergone by the 

 blood parasites in these experimental animals, their movements, microscopic struc- 

 tures, reaction of the blood cells toward them, and other related matters. A brief 

 bibliography of the subject is appended to the article. 



Experimental trypanosome diseases, L. Halbebstaedter (Centbl. Bald, [etc.'], 

 1. A>>t.< Orig., 38(1905), No. 5, />/>. 525-532, pi. 1). — The author reports in consider- 

 able detail the degrees of infection of white mice and rabbits with the trypanosomes 

 of dourine, mal de caderas, and nagana. The technique of staining trypanosomes is 

 also briefly considered. 



On trypanosomes and their presence in the blood of Brisbane rats, ( '. J. 

 Pound (Proc. Roy. Soc. Queensland, 19(1905), .V". /, pp. 33-38). — In recent years 

 the author has frequently observed trypanosomes in the blood of rats. Notes are 

 given on the technique of examination of fresh and stained specimens of rat blood 

 containing the trypanosome of surra. 



Anew endoglobular hematozoan, .1. J. Vassal (Ann. Inst. Pasteur, 19 (1905), 

 No. 4, pp. 224-231). — An endoglobular protozoan is found in Sciurus griseimanus. 

 Inoculation experiments showed that this organism is not pathogenic for man, 

 monkeys, rabbits, guinea pigs, or pigeons. Brief notes are given on its appearance. 



The spread of plague infection by insects, W. Hunter (Centbl. Bakt. [etc.], 1. 

 Abt:, Orig., 40 { 1905 \, No. J, pp. 43-55). — From a review of the literature of the sub- 

 ject and from the author's experiments it is concluded that insects may carry Bacillus 

 pestis and may. therefore, be the means of disseminating this organism over wide 

 areas. 



Sucking insects, BUCh as fleas, bugs, etc., mechanically convey infection from place 

 to place in the same manner as other insects. Apparently the danger from the hites 

 of the insects has heen exaggerated. It appears that the spread of infections diseases 

 by insects is accomplished indirectly by the deposition of plague bacillus on foods, 

 clothing, and household material. 



The tapeworms of Australia,' N. A. Conn (Agr. Gaz. N. S. Wales, 16 (1905), 

 No8. .', pp. 153-168; 3, pp. 909-219; 4, pp. 301-318; 7, pp. 619-631, figs. S4).— The 

 anatomy of tapeworms is discussed, and notes are given on the methods of collecting 

 them for study and on the life history of these pests. In the special discussion of the
