    cellular growths constitute perhaps the type of the connective- tissue tumours, whilst fibromata represent those in which the fibrous tissue predominates ; myxomta, those in which the mucous or embryonic matter is most abundant; fasciculated sarcomata, those in which the embryonic tissue has already undergone a trace of organization and evolution in the direction of connective tissue ; and lipomata, those in which fatty matter is very abundant. The epithelium being more exposed, is even more subject to perverted development than the connective tissue ;. we have, therefore, simple epithelial growths; or when, as is commonly the case, they assume a papillary structure, papillomata are formed. From the abnormal evolution of the glandular elements, we have cystic growths and adenomata, whilst the morbid production of blood-vessels gives rise to vascular grozuths, or angciomata. Papillomata are by far the most frequent of all the benign growths in the larynx. In my ioo tabulated cases, 67 were judged to be of this character.1 These growths occur at an earlier period of life than the other kinds of tumours, nearly all cases found in the first decennial period being either papillomatous or benign epithelial. In the cases of congenital growth collected by Dr. Causit,2 and in those now reported by myself, the neo- plasms have, when examined, generally been found to be of a warty character. The (supposed) congenital tumours in the Museums of St. Bartholomew's3 and St. Thomas's Hopitals 4 are likewise of a warty structure. The rate of growth in this class of tumours varies greatly, but it is generally most rapid at the inception. In one 1 A microscopic examination was made in 29 instances. In Appendices A and B, where the microscope was not used, and the nature of the growth was merely inferred, the pathological character is bracketed at the heading of each case; thus, (Papillomatous) Growth on Right Vocal Cord, &c, means that the growth was inferred to be papillomatous ; but where the adjective is written without brackets, a microscopical examination will be found accompanying the description of the case.
