Glandular Carcinoma.—Carcinoma of theacinous glands presents the same alveolation ofthe stroma as squamous-celled carcinoma. Themorphology of the cells being similar, the gland-ular spaces correspond with the connective-tissuespaces, in which, in the latter variety, the epithe-lial cells estabHsh centres of growth and formthe alveoli.
