Bending over the severed neck, his face less than an inch from the wound, he maneuvered his tweezers under the loupe, dug them into the neck--D'Agosta almost had to turn away--and stretched out what looked like a rubber band but was obviously a large vein. He snipped off a short piece and dropped it in a test tube, dug around some more, pulled out another vein, snipped and stored it, as well. And then he spent another several minutes examining the massive wound, the tweezers and test tubes in almost constant employment.
