After section and degeneration of the auriculo‐temporal nerve in cats, parotid secretion could still be elicited by injecting eserine into the gland, by application of citric acid to the tongue or by electrical stimulation of afferent oral nerves, and choline acetyltransferase activity could be demonstrated in extracts of the gland. The secretion obtained was not mediated via sympathetic nerves, although electrical stimulation of such nerves caused some secretion from most glands. Cholinergic secretory fibres mainly or wholly responsible for the remaining secretion after section of the auriculo‐temporal nerve were traced along the internal maxillary artery.
