as well as the shape of the latter (fig. 366, A, B). Thus, around certain 



globular structures, such as fat 

 cells and the terminal vesicles of 

 racemose glands, we find bag-like 

 nets of vessels, and also about the 

 outlets of follicular mucous mem- 

 branes a circular interlacement of 

 the latter. 



The cells of an hepatic lobule, 

 which have a radiating arrange- 

 ment, as depicted in fig. 328, p. 

 345, produce also a radiating 

 course in the capillaries of the net- 

 work of the part, which is pri- 

 marily bag-like (fig. 367). Again, 

 in those parts whose structural ele- 

 ments are elongated and regularly 

 grouped, we find the meshes of 

 the vascular web likewise much 

 drawn out, as it were, and verv
