The abdominal branches and the arteries of the lower limbs areusually more susceptible than the subclavian and its branches. Thevertebral and larger arteries at the base of the brain are not infrequentlvaffected. It is particularly prone to occur around smaller branches givenoff by larger trunks; at such points it gives rise to elevated rings surround-ing the lumen of the afferent vessel, the sectional area of which is dimin-ished. By reducing the blood-carrying capacity of the involved vesselsthe nutrition of the organs supplied by such structures is necessarilyaffected. Diffuse, nodular, and linear types of the affection have been des-cribed. The first manifestation of the condition consists of a grayish ormilky, semi-translucent opacity of the intima. never universal, but con-fined topatclie^ bore and there; this is followed by elevation of the patches,

The opened aorta is the seat ofthe following lesions: .1. False aneurysm of the aorta dissecting in the media. B. Point of maximum dila-tation; the vessel at this point is calcareous. C. Three small aneurysmal sacs; the area adjacent is calcareous.D. Small ancur>5mal sac just above bifurcation of aorta.

Fatty changes in the nodulegive rise to a pale-yellow spot in the center, wdiich spreads throughoutthe entire area involved. Deformity of the vessel is manifested bythe occurrence of button-like elevations, usually most marked where abranch is given off, and irregular dilations. The studies of Sailer andPfabler^ indicate that the vessels are elongated as well as dilated. Acentral necrosis in the atheromatous areas, wit
