AMITOSIS 41 



salamander seem to support and afford a firm foundation for Child's 

 work. 



We have, then, apparently, another kind of amitosis which cannot 

 be explained in the same way as the follicle cell's divisions and other 

 terminal kinds can. It appears to be the same process morphologically, 

 but produced by different conditions and leading to different results 

 that we cannot, as yet, differentiate from the conditions that control the 

 first kinds of amitosis mentioned. 



Technic. The technical methods for the last two sections are the 

 same as for the section on the cell. The cricket's egg follicle epithelium 

 is best studied by fixing the ovaries in picro-acetic, washing in alcohol, 

 and then stripping the epithelium off with needles and staining it with a 

 weak solution of methel green and acid of fuchsin. Great care is neces- 

 sary to avoid taking the tough egg membrane off with the epithelium, 

 as it takes the methel green so strongly that nothing else can be seen 

 through it.
