    SUBCUTANEOUS TISSUE. to an excessively disagreeable odour (bromidrosis), due to the presence of an organised ferment. Diminution of perspiration is seen locally in many chronic skin affections, and generally in almost all conditions of pyrexia, in diabetes, and sometimes in the cirrhotic form of Bright's disease. It also occurs in cases of profuse vomiting or profuse diarrhoea where much liquid is leaving the body. The perspiration may be coloured yellow from the presence of bile pigments in cases of jaundice, and in uraemia it may hold in solution large quantities of urea. In certain rare cases it has been observed to have a blue colour; and still more rarely extravasation of blood on to the surface of the skin has been observed. Condition of the Subcutaneous Tissue.—There are three pathological states to be noted under this head—viz. {a.) Adi- posity ; {b,) CEdema; and (<r.) Emphysema. {a.) Adiposity. (a.) Adiposity or corpulence^ when it passes the limits of health, is a very important condition. It is characterised by the deposit of fat, chiefly in the subcutaneous, the subserous (omentum and mesentery), and intermuscular connecting tissues, and is usually associated either with a plethoric or an anaemic state of the body. The muscles are weak, the heart weak and dilated, the pulse small, rapid, and irregular. Palpitation and dyspnoea occur on exertion, and attacks of angina pectoris are not rare. The signs of bronchial catarrh are often present, and perspiration is usually excessive. In very corpulent persons the sexual functions are weak, and sterility is common. These functions appear to be intimately related to the deposition of fat. Where the sexual functions are absent, as in eunuchs and in women after menstrua- tion has ceased, adiposity is common. Sugar is often present in the urine of very corpulent persons. Corpulence is most usually hereditary, but is sometimes brought on independently of this by
