Summary

The object of study was the character of the growth of the submaxillary salivary and the external orbital glands. The weight of the glands, the size of their lobules, acini, nuclei, and the mitotic activity of the secretory cells were determined. It was found that up to the age of 40 days the increase in the gland weight is due mainly to the formation of new acini; the latter takes place by proliferation of the cells of the terminal portions. After 40 days, the formation of new terminal portions occurs in a slight degree. The growth of the gland by the age of 75 days and later is due exclusively to an increase in the size of all structural components of the organ, and in the submaxillary gland also to the appearance and growth of convoluted ducts.
