The Salivary Glands.-Hyrtl describes parotid, buccal, and submaxillary glands, but there is also a sublingual glaud 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 glaud is misleading. H e suggests that probably 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 iu the ordinary way.
