 made out. In this paper he hazarded the guess that the so-called 

 multinucleate stage of Amaha proti us was in reality an ordinary 

 form of Amoeba infected with some species of Allogromia. ^his 

 idea was undoubtedly suggested hy the superficial resemblance 

 between Prandtl's infected atmeba' and the photographs of tlie 

 multinucleate Amaba protcus. Added experience would un- 

 • juest ionably have altered this conclusion, but the untimely death 

 of this brilliant young investigator put an end to a career of 

 great promise. 



It was probably such experience that prompted Doflein to 

 refrain from surest ing the possibility of an infection of Ammba 

 proteus with some species of Datacard's Xucleophaga. Doflein 7 

 found that the giant nucleus of Amabn r<sp< rtilio is a degenera- 

 tion nucleus due to the presence of an intra-nuclear parasite
