In the cross-circulation experiment of October 7th, 1892, chloroform was administered to the fed and carried to the feds heart only and not to its brain. The tracingof this experiment shows that concentrated chloroform inhaled in the most rapid manner possible and conveyed to the heart only did not produce anaesthesia, or failure of the respiration, or fall of blood pressure; in fact it produced no effect on the animal of any kind. Taken together the two experiments complete and terminate the work of the Hyderabad Commission. They prove that chloroform has no direct action whatever on the heart, and consequently that the fall of blood pressure caused by the administration of chloroform is not due primarily or in any direct manner to a weakening of the hearts action. They further prove that the fall of blood pressure, which is a normal condition of chloroform anaesthesia, is due to the direct action of chloroform on the vasomotor center in the medulla oblongate--i. e. , to vaso-motor narcosis. It is for this reason that the fall of blood pressure is, as the Commission has never attempted to make its conclusions retrospective; personally I have had in times gone by far too many of what my friend Dr. Dudley Buxton calls narrow shaves to feel anything but the most profound sympathy for any man who has an accidental death under chloroform; but it is obvious henceforth, if chloroform is to be employed at all, it must be administered in accordance with the principles we have all along advocated. Now that chloroform syncope, that bogey of the trained physiologist, has been got rid of, and we know that the heart cannot be weakened under chloroform except by interference with the breathing, there need be no difficulty in recogni. . .
