Injection of Chloric Acid into the arteries - Dog weighing 15lbs. Tubes inserted as in the last experiment; pressure 7 to 8 inches: 15 drops of a concentrated solution of chloric acid in 3 iij. Of water were injected into the axillary artery. The pressure immediately rose: in 8 it was at 12in. Respira tion was arrested in The action of the heart continued regular, oscillation 1in.; at 2' the pressure was 9in., at 3' 30 7in.; at 4' it rose to 9in., although the animal lay to all appear ance dead (no movement since the first arrest of the respiration); at 6' 30 pressure at 5in., heart beating regularly; at 7' it rose to 6z3in. This was accompanied by a slight movement of the tail and collapse of the parietes of the thorax by which some air was expelled from the lungs. The pressure now gradually diminished: at 10' after the injection it was at 2in.; and the circulation then seemed suspended. On opening the thorax the ventricles were found contracting rhythmically; auricles still; both cavities contained dark blood lungs natural.
