Let us turn again to the experiment just quoted. No anaesthetic is mentioned. Curare was administered, the sole effect of which is to render the living animal as motionless as a corpse. Three times the greta nerve was electrically "stimulated," and each time there was that RISE OF BLOOD-PRESSURE which we are told upon the highest authority was the "ONE OBVIOUS WAY" of determining the presence of pain. Keeping in mind this testimony of the professors of physiology at the Universities of Oxford, of Cambridge, and of London, that if pain were present during a vivisection IT WOULD CAUSE A RISE OF THE BLOOD- PRESSURE, let us now examine a little more carefully some of the experiments referred to in the volume reviewed in the previous chapter. We have had assurances of their painlessness. But to the scientific man assurances are of little value as compared with the testimony of the instrument. Were any of these experiments associated with a "RISE IN BLOOD-PRESSURE"? It is unnecessary to study them in their relation to other phenomena. In the early "stimulations of a nerve trunk, a rise in blood-pressure was always produced"; but after a number of repetitions the time came when no effect was produced, or the pressure fell; the point of exhaustion had been reached. But let us note what the instrument recorded. The italics are ours. EXPERIMENT 5. "Under incomplete anaesthesia, CRUSHING OF FOOT CAUSED A VERY SHARP RISE, followed by an equally sharp decline of pressure. This was repeated several times." (The author also tells us that "under full anaesthesia, crushing of the paws" caused a rise. One may question the completeness of the insensibility.) EXPERIMENT 8. Fox terrier, two years old; ether.... CRUSHING OF THE PAW WAS ATTENDED BY IMMEDIATE RISE..... Crushing of the fore-leg WAS ATTENDED BY A RISE.... Crushing of the foot, ATTENDED BY A RISE. Cutting skin of thigh and leg was ATTENDED BY A RISE. EXPERIMENT 9. "CRUSHING OF THE PAW WAS FOLLOWED BY A RISE, and continual cutting and crushing of the paw BY A STILL FURTHER RISE OF PRESSURE." EXPERIMENT 17. Several loops of intestines were withdrawn and placed IN BOILING WATER, ATTENDED BY A RAPID RISE of the blood-pressure, followed soon by a fall. EXPERIMENT 28. Hip-joint amputation made on both sides caused a rise in pressure. GRASPING SCIATIC NERVE WITH FORCEPS and MAKING TRACTION (pulling upon the nerve) CAUSED A RISE. EXPERIMENT 36. Small white dog.... HOT WATER introduced into abdominal cavity PRODUCED A RISE. EXPERIMENT 59. Spaniel, female; weight only 13 pounds. It has "been nursing its puppies," and is very cross. Duration of experiment, one and a half hours. Manipulation of ovaries caused slight RISE OF BLOOD-PRESSURE.
