DESCRIPTION OF PLATES II AND III,

Innominate Aneurism treated by Distal Ligature of Carotid and Subclavian Arteries with a tendon ligature (Mr. C. T. Dent).

PLATE II.

Transverse section of artery showing tendon ligature in sitû, × 45. a. Carotid artery. b. Lumen of artery. c. Shows rupture of inner coats. d. Tendon. e. Infiltration of small cells splitting np tendon into longitudinal bands.

PLATE III.

FIG. 1.-Shows elongation of cells, and development of new bloodvessel in the tendon. X 200.

FIG. 2.-Twice natural size. Longitudinal section of artery showing ensheathing lymph and tendon ligature in sitû. The vessel is completely occluded. The clot is less perfect on the proximal than on the distal side of the occlusion.
