Abstract
The main object was to measure the pitch-discriminating capacity of dogs when tested by the same alimentary-motor method applied by the author to cats. In some exps. simultaneous records of salivary and motor responses were taken; the 2 methods give similar end-results, but the responses may differ in latent period, duration, interval activity and inhibition. The capacity for pitch discrimi-naton of pure tones in the dog is about 1/3 of a tone as against 1 whole tone in the cat. The dog therefore has a better acoustic analyzer.
