Resorptive symptoms of intoxication after injection of cocaine in cats. Motor and vegetative arousal stages, tonic-clonic spasms and their spread in the motor system are shown in the individual phases of the poisoning.

Parasympathetic irritation is generated in the test animal by subcutaneous injection of muscarine. Salivary secretion, miosis, convulsive evacuation of thin feces and severe shortness of breath as signs of intoxication with a parasympathomimetic. The symptoms of intoxication are reversed by subcutaneous injection of atropine.

Two cats housed in a glass box, one of which had received a small amount of atropine in the preliminary experiment, are exposed to ether vapors with the result that only the animal which had not been pretreated began to salivate (profusely).
