EXPERIMENT 33. "ON BURNING A PAW UNDER LIGHT ANAESTHESIA, THERE WAS A
RISE OF PRESSURE OF 19 MILLIMETRES."

What is "LIGHT anaesthesia"?

It is a condition which a few drops of chloroform will produce; a
state in which the loss of consciousness is so slight that any pain
may be as keenly felt as if no stupefying agent had been given. What
are we to think of a statemnet that in a condition of such light
slumber the keenest of pains--THE BURNING OF LIVING FLESH--INVOLVED NO
SUFFERING? How can one speak with authority on a matter like this
against the evidence of the "one obvious sign" of sensibility? When
the paws of the miserable animal were burned, was there not the rise
of blood-pressure which indicated suffering? "Pain would cause a rise
of blood-pressure," said the professor of physiology of the University
of Cambridge. Should we find the significant rise of the
blood-pressure in other experiments where fire was used for the
"stimulation" of the nerves? Let us see.

EXPERIMENT 2. "On burning a paw, there was a RISE OF PRESSURE OF 10
millimetres. Stimulation of sciatic nerve resulted in
A RISE of systolic pressure."
EXPERIMENT 4. "11.45. On burning a paw, there was A RISE OF PRESSURE.
" 1.27. Sciatic nerve stimulated; RISE OF
BLOOD-PRESSURE."
EXPERIMENT 6. "Burned a paw. A RISE OF PRESSURE of 4 millimetres
resulted."
EXPERIMENT 12. "On burning a paw, there was a RISE OF PRESSURE of 16
millimetres."
EXPERIMENT 14. "On burning a paw, A RISE OF 12 MILLIMETRES, followed
by a temporary fall, and then a rise to a higher level.
"On burning a paw, there was A RISE OF BLOOD-PRESSURE
OF 2 MILLIMETRES."
EXPERIMENT 15. "11.12. On burning a paw, there was A RISE OF PRESSURE
OF 8 MILLIMETRES.
"11.36. On burning a paw, there was A RISE OF PRESSURE
OF 12 MILLIMETRES."
EXPERIMENT 16. "Dog. Condition good.
"11.22. On burning a paw, there was A RISE OF PRESSURE
OF 22 MILLIMETRES.
"11.33. On burning a paw, there was A RISE OF 29
MILLIMETRES.
"11.44. Contrl. On burning a paw, there was A RISE OF
24 MILLIMETRES.
"12.26. On burning a paw, there was A RISE OF PRESSURE
OF 8 MILLIMETRES.
"12.35.
