fi2 SUMMARY OF CURRENT RESEARCHES RELATING TO 



The species is probably T. brucei. An account is also given of the dis- 

 covery of similar parasites, not yet particularly identified, in cattle from 

 Kodok. 



Effect of Human and Ape Serum on Trypanosoma.* — A. Laveran 

 finds that not only are Cynocephali immune to Trypanosomes, but their 

 serum gives positive results when inoculated on infected rats and mice. 

 The trypanosomes disappear from the blood under strong inoculation. 

 Normal human serum has also a killing effect, in fact it is stronger 

 against T. evansi, T. brucei, and T. equinvm than ape's serum. 



Hsemogregarine in Psammodromus algirus.f — H. Soulie describes 

 a new species from the blood of this reptile. He found one individual 

 in every three infected, but without injurious effect. When young the 

 parasite is an elliptical body, little less than the nucleus of the red 

 corpuscle ; the adult is generally reniform. In rare instances it was 

 found free in the plasma. This species he names H. psammodromi.
