The chemotactic power of the toxin produced by Sclerostomum bidenta-

 isni for the polynuclear eosinophile leucocytes. It has no chemical relation to 

 the toxin produced hy the jjlanders bacillus, which exercises cheniotaxis i)riu-

Comparative investigations of the nodules and neoplastic lesions of the 

 intestines of the horse in their relation to glanders, I'. Hummel {Arch. WisH.

 S6 (1909), Xo. o, p. IS.'i). — It is concluded that the nodules and neoplastic 

 lesions of the intestines of the horse are usually of parasitic origin. The lesions 

 of the intestinal wall produced by entozoa are always characterized by the 

 appearance of eosinophiles. Glanderous lesions of the uuicous meml)rane of the 

 intestines appear to be very rare. 



Contribution to the pathological anatomy of rinderpest, S. Arloing and

 disease, which ravaged Egypt in 1904 and 1905. 



The therapeutic immunity reaction in the differentiation of trypanosome 

 species, B. T. Terry (Jour. Expt. Med., 11 (1909). Xo. 6", pp. 802-809 ).—•' It 

 is evident that the guinea pig is an unfavorable animal in which to preserve the 

 virus, if the therapeutic immunity reaction is to be employed in the differentiation 

 of trypansome species, for the experiments clearly show that trypanosomes 

 of common origin, never in contact with medicaments of any sort, may behave 

 like different species after having been preserved in these animals for 1 year." 



Preliminary note on Trypanosoma eberthi (=Spiroch8eta eberthi) and 

 some other parasitic forms from the intestine of the fowl. C. H. Martin 

 and Muriel Robertson (Proc. Roy. Soc. [London], Scr. B, 81 (1909), Xo. B 

 5Jf9, pp. 385-391, pi. 1). — In a preliminary investigation tlie authors examined 

 the cecal and rectal contents of 14 fowls of various ages and at various stages 

 of digestion. During the investigation flagellate parasites of 4 types were found 

 in the cecum. 



In 3 of these types large numbers of individuals were found in which the 

 characters of each group were sharply marked ; at the same time numerous 

 transitional forms were found. The first form, which the authors considered 

 to be T. eberthi, is characterized by a rather elongated body, a very well 

 marked undulating membrane along the edge of which a flagellum runs from 

 the anterior end of the animal to end freely at the posterior end. A second 

 form (Trichomonas condition) is described as a typical Trichomonas of 

 variable size, apparently resembling the form described by Wenyou from the 

 mouse. The third form (Monocercomonas condition) is roughly egg shaped. 

 The fourth form was a sharply marked type, found in small numbers on two 

 occasions, with an anterior and posterior trailing flagellum which can be coiled 

 around the body. It is of very small size, roughly half the size of the smallest 

 first form seen, and of approximately torpedo shape. Every fowl examined 

 was found infected with one or other of these flagellate forms.
