Trypanosoma in Sleeping Sickness.* — Aldo Castellani describes a 

 species of Trypanosoma which he found in the cerebro-spinal fluid of a 

 marked case of sleeping sickness. He suggests as a working hypothesis 

 that the disease is due to this parasite, aud that at least in the last stages 

 there is a concomitant streptococcus infection. 



Developmental Forms of the Trypanosome found in Sleeping Sick- 

 ness.f — Aldo Castellani finds a number of forms structurally different — ■ 

 typical adult forms, atypical adult forms, forms in different stages of 

 longitudinal division, Rabinovitsh-Kempner bodies and Plimmer- 

 Bradford amoeboid forms. It seems likely that the multiplication of 

 longitudinal division is not the only mode of reproduction. 



Coccidia in Sheep.J — Moussu and Marotel describe a rare occurrence, 

 the presence of Coccidia in the wall of the small intestine of the sheep. 

 Four cases have been previously reported. The disease is a new one,, 

 and the authors propose to call the parasite Coccidium faurei sp. n.
