GOLGI IN GLAND CELLS

Bowen states and his figures prove that " a very close topo- 

 graphical relation was found between the Golgi material and the 

 developing secretory granules." 



In a second paper (10b), Bowen deals with lipoidal secretions 

 found in the so-called skin glands — inguinal gland of the rabbit, 

 Meibomian glands of the cat, oil glands of the chicken and duck,

 apparatus to the secretory cycle (after Bowen (10a) ). A-D, in 

 mucous cells from the submaxillary gland of the cat. E-H, 

 in serous cells from the parotid gland of the cat. A and E, show 

 commencement, D and H, the end of the secretory cycles.

Harderian gland of the rabbit. In these glands the general pro- 

 cess resembles that in the serous gland cells. The Golgi apparatus 

 hypertrophies and appears rather flocculent like that described 

 by Cuttaneo {vide 11) for the mammalian egg. Bowen thinks this 

 is very significant. The granules of lipoidal substance grow in 

 size, associated with Golgi material, which shows a decided 

 tendency to fragment. This tendency to fragment increases 

 as the cycle progresses, and the granules are inclined to run
