    The vessels which were transmitted from the arch of the aorta, exhibited remarkable and inter¬ esting appearances* The trunk of the arteria innominata, and the trunks of the left carotid, and of the left subclavian arteries, were ail of them in a considerable degree plugged up with a growth from the lining mem¬ brane of the artery, having the same general na¬ ture and appearance as the lining itself, and with¬ out any ossific deposition. In the arteria innominata, this preternatural growth extended, irregularly, about an inch up the vessel, the calibre of which was reduced by it, to less than one-third of its usual dimension. In the left carotid, it was confined nearly to the opening of the trunk into the aorta; but the orifice was di¬ minished to such an extent, as to admit not more than the passage of a common-sized probe. In the left subclavian, it extended about half an inch up the vessel, the cavity of which it had diminished to the extent of a small slit. No other morbid appearances were observed. It was a matter of much surprise to me, that with alterations of structure so considerable as those which I have described, no symptoms of previous indisposition should have manifested themselves. More particular inquiry, however, convinced me.
