ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 339 



Hsematozoa of Beri-Beri.* — Dr. F. Fajardo alludes again to the 

 protozoa observed by him in cases of beri-beri.f The present communi- 

 cation is really supplementary to the first, and supplies drawings of the 

 appearances observed in the brain. All the parasites, which have much 

 general resemblance to those of malaria, contain more or less pigment in 

 the form of granules. Lively movements were noticed in these granules 

 as long as forty-eight hours after death. 



Infectious Jaundice of Dogs.J — P. Leblanc has found that the in- 

 fectious jaundice of dogs is due to the presence of a hromatozoon, quite 

 like those described by Marchoux in dogs of Senegal. Though having 

 some resemblance to the parasites causing hsemoglobinaemia in cattle and 

 sheep, they are much larger, varying in size from 2 to 4 //.. They are 

 most frequent in the red corpuscles, wherein two or three may be ob- 

 served ; in the plasma they are rare. The nucleus is a small spot or 

 line, always lying close to the periphery of the parasite. They were 

 often observed undergoing division within the corpuscles. In shape 

 they are mostly spherical or oval, rarely pyriform. They are best stained 

 by Laveran's method.
