One drawback to suture of blood-vessels is the difficulty of obtaining proper suture material, as silk of suitable fineness and smoothness and tensile strength is not readily procured. To meet this difficulty we decided to test a material universally distributed, namely, human hair.
Light brown hairs of medium fineness about 8 inches long were tested as to tensile strength and found to be stronger than the silk previously employed. One of the carotid arteries of a recently killed dog was divided and the ends reunited with the hair as suture material. Hair proving satisfactory in this preliminary operation, a number of hairs were then threaded, and tied into sterile needles (No. 14 cambrics) and placed in 10 per cent. aqueous formalin.
A medium-sized dog was anesthetized and the left common carotid artery and corresponding internal jugular vein were exposed and divided. The peripheral end of the artery and the central end
