The intimal changes consisted from small fibrous tissue-like i)hicquesto complete involvement of the entire wall; there was no evidence ofdefinite fattj- change in these placques, nor were wandering cells in evi-dence, as in ordinary arteriosclerosis. These changes were found in 11out of 12 cases and they were quite marked in 7; in 3 they were quitedefinitely present. Tlie more marked vessel changes, that is those which. Fie. 16.—Ob. Path.
