Abstract THOUGH the avian lung has been studied for many years (Campana, 1875; Fisher, 1905; Locy and Larsell, 1916 a, b; Akester, 1960), the relationship of structure to function is still incompletely understood (Vos, 1934; Dotterweich, 1936; Hazelhoff, 1951; Biggs and King, 1957; Shepard et al., 1959). The presence and possible role of a pulmonary surfactant in avian lungs is contested (Miller and Bondurant, 1961; Pattle, 1963). Electron microscopy has revealed osmiophilic inclusions in the epithelium of tertiary bronchi and atria (Nagaishi et al., 1964; Tyler and Pangborn, 1964), and a unique laminated membrane surface of these epithelial cells (Tyler and Pangborn, 1964). Similar inclusions in the alveolar epithelium of mammals are thought to be the source of the pulmonary surfactant (Klaus et al., 1962). Histochemical methods, although mainly qualitative, permit precise localization of chemical activities among the various tissue components of an organ. This type of information is not obtainable …
