Curarize

Curarize the frog sufficiently to paralyze the motor nerves.

Curarize a large frog, and remove the arches from the fifth, sixth, seventh, eighth, and ninth vertebræ.

It is difficult to curarize vitally stained frogs, and thoroughly curarized animals may be restored by injections of dyestuff (Congo red, trypan blue).

In addition, I do not smoke nor does anyone in my laboratory when we curarize rats.
