least under dentinal calcium phosphate, but intermediate under this material in the presence of magnesium hydroxide and cortone acetate; it was only slight in the case where OH cycle resin was present. Appreciable metaplasia of pulp tissue has only occurred under calcium salts and in all these cases the calcium ions have been present in association with a pH above neutral. Where inflammation existed there was no metaplasia, although such was occurring in non-inflamed areas of the same tissue. Preparations such as magnesium hydroxide and OH cycle resin, used to make noncalcium ions available, have not produced metaplasia, nor did they modify degenerative change. Although magnesium is known to be synergistic with phosphatase, no metaplastic changes occurred with this material alone. Other materials used did not produce changes in the desired direction. The ability of the connective tissue elements of the dental pulp to undergo metaplasia into all forms of soft or hard connective tissue has been demonstrated. The various stages of metaplasia of fibroblasts to odontoblasts have been demonstrated. The findings of Manley, and of Zander and Glass, regarding the chronic inflammatory effect of zinc oxide-eugenol and phenol, on pulp tissue, have been confirmed.” A. J. A.

Primary carcinoma of Stenson’s duct is rare. The case reported is that of a 46 year-old man whose history was that of intermittent swelling of the left side of the face for four months. There was an indurated, firm, tender mass in the left cheek, posterior to the orifice of Stenson’s duct. It was first thought that the lesion was probably that of a calculus embedded in inflammatory tissue. The patient refused surgery and did not return for two months, at which time it was apparent that a tumor was present. A biopsy was performed and reported as squamous carcinoma. Irradiation therapy was given (7900 r. in seventeen doses over a thirty-one day period). The results were good and there was no evidence of recurrence eighteen months after treatment. T. J. C.

A case report is presented of a melanotic epithelial tumor, closely affiliated to adamantinoma, in a baby girl, 6 months old. Most likely the tumor developed from epithelial cells spread from the embryonal gingiva. The tumor parenchyma consists of two not fully differentiated elements which are (A) large gonglobate or polygonal cells with much granular believed to be epithelial cells: protoplasm, a large, pale nucleus and mostly various melanin granula; (B) smaller cells with No pigmentation is found on the oral little plasma, with a nucleus rich in chromatin. The tumor is clinically benign, in spite of the polymorphous cells, its partly mucosa. Also, the absence of destructive growth, infiltrating growth, and evidence of mitoses. inflammatory changes, and pigmentation of the stroma indicate its benignancy. Among the congenital tumors of the jaws this growth takes a particular position. R. H. B.
