title: Plasma cells in vertebrate paraocular glands.
abstract: The Harderian and lachrymal glands of eight mammals and two reptiles were examined histologically for plasma cells and the extent of infiltration compared to that in the Harderian gland of the fowl. Moderate accumulations were observed in one or both glands of the goat, sheep, cow, horse, dog and pig, but only few cells were present in the glands of the mouse and rabbit. No plasma cells were encountered in snake glands but some were detected in both glands of lizards. It is suggested that glandular secretions contribute to local immunity.
