    membrane of the mouth, between the mylo-hyoideus and hyo-glossus muscles, accompanied by the submaxillary duct: it then ascends above the sublingual gland and expands into a broad and flat nerve, assuming a ganglionic appearance ; between the lingualis and genio-hyo-glossus, in the situation of the point of the wedge, it then com- municates with the ninth or hyo-glossal nerve in passing over the insertion of the hyo-glossus muscle. It then divides into several branches, which accompany the dorsal artery: these are again divided into smaller branches, and surround each terminal branch of the dorsal artery just beneath or on a level with the dorsum of the tongue, through which they penetrate to form the gustatory papillae, whilst their extreme termini surround the terminal extre- mities or papillae of ranine artery at the tip of the tongue. It would not be a difficult task to show the connexion between the secondary senses of sight, hearing, smell, taste, and touch, through the media of nervous communi- cation with the sensorium itself. Anything, for instance, takeu into the mouth of a very cold nature, such as ice, will produce a painful sensation in the teeth. Their enamelled coverings have no appreciation: if the teeth appreciate the cold, it is by a momentary communication through the gustatory nerve with the inferior dental. A painful sensation may be felt in the ear, or a sudden deaf- ness which gives place to a singing noise: this is appre- ciated through the gustatory nerve communicating with the chorda tympani. If anything very hot be taken into the mouth, a heated solid or fluid, or mustard, through the connexion betw^een the first division of the fifth and that between the oculo-muscular or sixth nerve, the sen- sation is communicated to the eyes, and, through the nasal branch of the first division of the fifth, to the nose, causing
