Crile, however, noted a simultaneous increase in respi-ration in almost every instance. This could only have beendue to a meduUary reflex, and makes the same mechanism amore probable explanation of the hypotension. Simple paracentesis of the abdomen causes a slight faU inpressure, due to release of the intra-abdominal tension. Re-medi, who thinks shock is due principally to chloroform, saysthat laparotomies on dogs, without anaesthesia, cause only aslight lowering of mean carotid pressure, 2 to 8 mm. c.

The height was proportional to the severity ofthe traumatism. Schroeder, on the other hand, thinks theseoperations show a considerable lowering of pressure, those bythe vaginal route much less than the abdominal. He useschloroform narcosis, but thinks the laparotomy much moreprovocative of hypotension than the anaesthetic. Possibly thecombined effect explains the variation of his results from advocates the systematic charting of b
