subdepressed circular bodies, thicker at the middle than at the 

 circumference, which, with the connected sclerous, areolar, and 

 adipose tissues, raise the pectoral integument, at puberty, in 

 the form of two large hemispheres or ( breasts ; ' and, from a 

 little below the centre or apex of each, pro- 

 jects the ( nipple.' The base of the ' breast ' 

 corresponds to the interval between the third 

 and the sixth or seventh ribs. The gland is of 

 a firm texture and pale reddish colour : the 

 secerning follicles, when injected with mer- 

 cury, are just visible to the naked eye. Mag- 

 nified four times, they present the appearance 

 shown in fig. 609. They are aggregated in 

 clusters or ' glandules ' of different sizes, sus- 

 pended by the duct resulting from the union 

 of those of the follicles. The short or stem- 

 ducts open into a wide canal, and these, fig. 

 610, c, d, by successive unions, form dilated reservoirs of a coni- 

 cal form, ib. b, b } from the apices of which are continued the
