The influence of enlarged 138 REFERENCE HANDBOOK OF THE MEDICAL SCIENCES. tonsils upon the circulation is a matter of importance,deficient oxygenation of the blood not being the only re-sult which may be traced to them. Anaemia is a com-mon symptom, and one which is often particularly well-marked in these cases. Some believe that enlargement ofthe heart by dilatation may be directly due to this im-poverishment of the blood. Disturbed cerebral circula-tion, as a result of pressure from the enlarged glands, hasbeen suggested by Chassaignac ; while a recent writerstates that he has found epistaxis to occur frequently inchildren suffering from hypertrophy of the tonsils, andmaintains that the haemorrhage is due to continuous press-ure upon the veins of the neck, producing chronic en-gorgement above, with perhaps chronic alteration in thewalls of the vessels. Pathology.—Chronic enlargement of the tonsils is a truehypertrophy or hyperplasia, in which, according to Vir-. PlG. 3943.—Hypertrophied Tonsil. Enlarged drawing. i,) chow, there is not only increase in volume of the gland,but an actual multiplication of all of its constituent epithelium covering the tonsil usually shows littlechange, but the papillae underneath are often more nu-merous and less elevated than in the normal state ; while,in the crypts, there seems to be a tendency for the mem-brane to become thinner as the bottom of the crypt isapproached. The substance of the gland may show one of two vari-eties of alteration. Either the lymphoid elements alonemay be increased in amount, the stroma of the gland be-ing little affected, or the fibrous tissue which constitutesthe stroma may be greatly in excess of the normal de-gree. In the latter condition the lymphoid elements maybe in excess, or there may be a condition of generalatrophy prese
