The Salivary Glands. — Hyrtl describes parotid, buccal, aud sub- 

 maxillary glands, but there is also a sublingual gland of considerable 

 size with the usual position and characters. It may be mentioned 

 in passing that Hyrtl's figure of the relations between Stensen's 

 duct and the buccal gland is misleading. He suggests that pro- 

 bably the buccal gland pours its secretion into this duct and 

 figures it as running close along the upper border of the gland. 

 In point of fact there is no connection between the two ; 

 Stensen's duct takes quite the usual course across the masseter at 

 a very considerable distance above the buccal gland, while the 

 latter in all probability opens independently into the mouth in the 

 ordinary way.

With regard to the submaxillary gland there is a feature of some 

 little interest. The secretion is collected (as described by Hyrtl) 

 into two main ducts, each of which receives the secretion of one
