    ( ) plexy, produced by extravasation, which is of all others, the most suddenly fatal—death rarely happens so soon. But the opinion «f Mr. Kite is not merely rendered improbable by analogy ; it is incontrovertably disproved by experiments. Mr. Coleman secured both the Carotids of a Dog, and in half an hour after suspended him by the neck. He died in four minutes. On examination, the vessels of the Brain were found less distend- ed than ordinary.* This experiment has been so often repeated with the same result, that there can be no doubt of its correctness. EXPERIMENT. I secured the jugular and thyroidal veins of a Cat by ligatures at the same moment; no symptoms of apoplexy were apparent. At the end of twenty minutes the animal was killed, and on removing the cranium, the vessels were found much distended, but there was no extravasation. This experiment was repeated on another animal, and the jugular and thyroidal veins remained jn ligatures forty five minutes—the result was the same. EXPERIMENT. The trachea of a Cat was laid bare, and an opening made just below the Thyroid cartilage, a cord was passed round the neck, immediately above the opening, by which it was suspended. Air was inspired through the opening in the trachea, and respiration went on without apparent inconvenience. There was no visible change in the colour of the lips, tongue or nose, and the eyes appeared perfectly natural. At the expiration of ten minutes, it was taken down, the hole in the trachea closed, and it breathed as nsual. It was again suspended in the same manner, and the open- ing closed. It immediately struggled violently, the lips, moso and * Coleman on Respiration, page 143.
