called it kinetonucleus. In recent years it has become known that 

 the blepharoplast of many flagellates responds positively to 

 Feulgen's nucleal reaction which indicates the presence of thymo- 

 nucleic acid or chromatin in this structure. 



The Golgi apparatus 



With the discovery of a wide distribution of the so-called Golgi 

 apparatus in metazoan cells, a number of protozoologists also re- 

 ported a homologous structure from many protozoans. It seems 

 impossible at present to indicate just exactly what is the Golgi

apparatus, since the so-called Golgi techniques, the important 

 ones of which are based upon the assumption that the Golgi ma- 

 terial is osmiophile and argentophile, and possesses a strong affin- 

 ity to neutral red, are not specific and the results obtained by 

 using the same method often vary a great deal. Some of the ex- 

 amples of the Golgi apparatus reported from various Protozoa are 

 mentioned on page 70. 



It appears thus that the Golgi bodies occurring in Protozoa are 

 small osmiophilic granules or larger spherules which are composed 

 of osmiophile cortical and osmiophobe central substances. Fre-
