    which cells are torn from their connections and allowed to take on independent growth. CLASSIFICATION.—In our present state of ignorance no satisfactory classification of tumours is possible. The one here adopted is based upon their histological characters. Tumours arising from mesoblastic tissues are arranged in three groups; th&fLrst, resembling the most highly differentiated tissues; the second, the ordinary con- nective-tissues ; and the third, the embryonic tissues. In dealing with tumours from epiblastic and hypoblastic tissues the same order is followed. For the sake of convenience, all cysts are grouped together at the end of tumours—though the great majority of cysts are not new- growths. Classification of Tumours. I.—Type of Higher Tissues.

Myomaia are tumours consisting of muscular tissue. There are two varieties—Uhabdomyoma and Leiomyoma. ]. Rhabdomyomata consist of striated muscle combined with varied but generally considerable amounts of connective-tissue. They are congenital and very rare. The kidney and testis are the com- monest sites. The striated muscle-cells in congenital growths of
