   “In the bulletin for April 24, 1911, of the French Association for the Study of Cancer was presented a paper by Alezais and Peyron on the "Histogenesis of Carotid Paragangliomata." This elaborate histologic study, however, contributes little new or of importance to our knowledge of the nature of carcinoma.”
