NUCLEATED CORPUSCLES. 19 



similar magnitude, gemmiparous when buds are separated 

 from a parent mass, as occurs frequently in vegetables. When 

 a corpuscle divides within a cell-wall, which remains unrup- 

 tured, the process of multiplication is called endogenous. The 

 nucleus seems to play an important part in the multiplica- 

 tion of corpuscles, being, at least in many instances, the first 

 part to divide. 



At present the weight of evidence appears to be in favour 

 of every corpuscle being derived from a parent. Certain 

 physiologists hold a contrary opinion; but there is no well 

 determined instance of these structures originating otherwise 

 within the body. 



The varieties of nucleated corpuscles found in different 

 situations will come under notice in the description of the 

 individual textures.
