CHAPTER VII. 



ABSORPTION. 



BESIDE the glands of B runner and the follicles of Lieberkiihn, 

 already described, there are, in the inner part of the walls of the 



intestine, certain glandular- 

 looking bodies which are 

 termed "glandulso solitaries," 

 and " glandulaa agminatae." 

 The glandulae solitariae are 

 globular or ovoid bodies, 

 about one-thirtieth of an inch 

 in diameter, situated partly 

 in and partly beneath the in- 

 testinal mucous membrane. 

 Each glandule (Fig. 37) is 

 formed of an investing cap- 

 sule, closed on all sides, and 

 containing in its interior a 

 soft pulpy mass, which con- 

 sists of minute cellular bodies, 

 imbedded in a homogeneous 

 substance. The inclosed mass 

 is penetrated by capillary 

 bloodvessels, which pass in 

 through the investing cap- 

 sule, inosculate freely with 

 each other, and return upon 

 themselves in loops near the 

 centre of the glandular body. 

 There is no external opening 

 or duct; in fact, the contents 

 of the vesicle, being pulpy 

 and vascular, as already de- 

 scribed, are not to be regarded 



as a secretion, but as consti- 

 tuting a kind of solid gland-
