    tion, the right ventricle of the heart was filled with blood, unlike that usually found in that cavity; being red, spumous, and apparently ar- terialized. The cause of the animal’s death was now sufficiently ob- vious: the atmospheric air had entered the cavity of the heart through the divided vessel. Another circumstance connected with the venous circulation, is also worthy of being mentioned. In an unsuccessful attempt to repeat the celebrated experiment of M. Magendie, on venous absorption, one of the platina tubes by which it was intended to form the chan- nel of communication in the femoral vein, was forced so far upwards within it, as to be beyond our reach. Upon searching for the tube, it was found as high as the right auricle of the heart!! This tube was two and one-eighth inches in length, and weighed thirty-two grains. Assisted by Mr. Chew, student of medicine, I afterward intro- duced into the right femoral vein of a sheep, a platina tube, one inch and one-fifth in length and weighing nineteen grains. The animal did not subsequently manifest any symptom of pain or uneasiness. He was killed about thirty minutes after the insertion of the tube: upon ex- amination, the tube was not discovered in the entire tract of the iliac vein, nor in the ascending cava, nor even in the right auricle of the heart. It was finally discovered, however, in the larger lobe of the left lung. Philadelphia, November, 1827.
