2 r 4 NUCLEI NOT FORMED FIR XT. 



four hours after the commencement of fever or inflam- 

 mation. 



So far from nuclei being formed first and the other 

 elements of the cell deposited around them, as is still main- 

 tained by some, they make their appearance in the sub- 

 stance of an already existing mass of bioplasm, as has been 

 already stated. The true nucleus and nucleolus are not 

 composed of special constituents differing from the bioplasm, 

 nor do they perform any special operations. Small oil- 

 globules, which invariably, result from post-mortem changes 

 in any bioplasm, have often been mistaken for nuclei and 

 nucleoli, but these terms if employed at all should be re- 

 stricted to the minute masses of bioplasm referred to. This 

 interesting question will be again referred to in the next 

 section. See figures in PI. IV, page 218.
