    Saliva has no action on proteids or fats, or on sugar, gum, etc. The saliva has no digestive power before the sixth month, hence flour foods cannot then be digested. THE SALIVARY GLANDS. The saliva is formed in three pairs of glands. One pair, the parotid glands, are situated in the cheeks, and open into the mouth by a small duct xhe Parotid (Steno’s) at the back of the second molar tooth Glands, on each side. These glands secrete a clear limpid saliva free from mucin. ^ 39* Prom a Section through a Serous or True Salivary Gland J part of the Human Submaxillary. a. The gland alveoli, lined with the albuminous “salivary cells;” b, intralobular duct cut transversely. The other two pairs are the sublingual and the sub- maxillary. The former are beneath the tongue, Suhiinguai and the latter are further back in the floor of the ^Iniary mouth, and open with the former by common Glands, ducts (Wharton’s). The saliva from these is more viscid, and contains much mucin.
