KecentlyMallory3 has found similar lesions in the arteries of the heart duringacute articular rheumatism. The end-result of such a lesion on healingmust show a permanent scar in the arterial wall. Jt seems reasonable. Marked arterial lesion found in an artery in the kidney following scarlet fever. to suppose that less severe infections of the same type which terminatein recovery may cause similar arterial lesions with an arterial scar carriedinto later life. The question immediately arises. Do repeated lesions ofthis sort lead to the so-called arteriosclerosis of old age? If such alesion heals with a partial occlusion of the lumen, it is reasonable to 2.
