"Cause not pain, lest you yourselves be afflicted."
From a small pet-bird of pink and green plumage, called in our language
the Nebo, is extracted an electricity known as the "Pain-luller."
The preparations previously used, though very serviceable, did not
fulfil all requisites, and they so seriously suspended the vital action,
that the patient often died in consequence. By means of the
"pain-luller" vivisection and the most difficult surgical operations can
be performed safely and painlessly, without any part of the system being
affected by the action of the "pain-luller," with the exception of the
nerves of sensation. We knew that the feeling of pain in animals depends
on the action of a particular set of nerves. When this pain-lulling
electricity is introduced into body, it is attracted to the nerves of
sensation, and the sense of feeling remains suspended during several
hours, whilst the other nerves and muscles--as, indeed, all the rest of
the organization--continue to perform their functions as in their normal
state.
