    CHAPTER IIL* THE ANATOMY OF CANCER. The elements on which the diagnosis of a surgical tumor is founded may be divided into two principal sets : the clinical and the anatomical. The former it is which we have been just considering ; the latter still remains for us to examine into. It would be foreign to my purpose to enter into any long disquisition on the naked eye characters of scirrhus and encephaloid; they are well known and have been well described.•]• But, for the sake of completeness, the following brief de- scriptions are here given: j — Scmhus {of the Breast) forms a hard, firm, compact, tough mass, that cuts clean, offering a sharply defined section. Such a section has a translucent, opalescent appearance; its general color is bluish-white (that of mother-of-pearl, or of a thin layer of diluted milk); but closer inspection shows it to be pervaded by a buff- colored, opaque substance, disposed either in the form of irregularly branching threads, or of pin-head sized * In a Natural History of Cancer, this Chapter should have preceded Chapter II.; iu the Diagnosis of Cancer the present is its proper sequence, t Vide especially Vol. II. of Mr. Paget's 'Surgical Pathology.'
