484 ox THE FEMORAL (iLAND OF OnXITIlORHYyCUUS, 



92% alcohol two days after the animals were killed. The weather 

 at the time was cold, so that the tissues were in very moderate 

 condition notwithstanding this delay. Transverse sections of 

 these were cut from pieces embedded in paraffin and also in gum. 

 The sections were stained in htematoxylin and borax carmine. 



The gland is of the compound racemose type. The duct, ti-aced 

 into the gland, divides repeatedly into smaller and smaller 

 })ranches — the final branches opening into the alveoli. Each 

 gland is divided into lobules (PI. x.xix. figs. 1 and 2), all of whichshow 

 numerous alveoli and ducts in a connective tissue stroma. The 

 alveoli are dilated, and lined b}'^ a single layer of epithelial cells 

 situated on a basement membrane. 



The epithelial cells (PI. xxx. fig. 1 a) are large, iri^egular in 

 shape, and have flattened nuclei at the deeper part of the cell. 

 The nucleus and that part of the protoplasm nearest the attached 

 end of the cell take the stains readily. The rest of the cell is 

 occupied by coarsely granular material which did not stain with 

 nuclear stains. This appearance corresponds to the condition 

 observed in the cells of a mucous salivary gland prior to the 

 discharge of its secretion. The portions of the ducts seen in the 

 sections (viz., the portions within the gland), are lined by a 

 single layer of large columnar cells seated on a basement membrane. 



The stroma (PL xxx. fig. 1 b) presents the usual characters of 

 white fibrous tissue. It is formed by the septa passing in from 

 the fibrous layer of the capsule which divides the gland into 

 lobules. 



The capsule consists of two coats : — 



(1) The fibrous one just alluded to (PI. xxx. fig. 1 c), cOnsist- 



, ing like the stroma of white fibrous tissue, and containing 

 a liberal supply of blood-vessels and nerves. 



(2) A layer of unstriped muscular tissue, three or four cells 



deep, situated outside the fibrous coat (PL xxx. fig. 1 d). 



Outside of these is the investment of fibrous tissue derived from 

 the deep fascia, which is not shown in the drawings, having Ijeen 

 removed in the process of dissecting out the glands.
