Abstract
The domestic chicken was used as an experimental model in which to demonstrate morphological and functional relationships of nasal organ systems, principally of mucous systems. Mucous secretions of olfactory, respiratory, lacrimal, and accessory areas were found to have clear histochemical differences, yet were sufficiently miscible in normal circumstances to form an unbroken, synchronously moving sheet. Changes induced experimentally in host physiology did not all affect the mucous components of given areas in the same way or to the same degree. Mucosal changes were produced by the following methods:
