The view that the nervous control of the bladder in the cat is compounded of sympathetic inhibition and parasympathetic excitation is inaccurate. Evidence is provided to show that in the cat and the dog the sympathetic and(parasympathetic nerves are each both excitor and inhibitor. The effects produLced by stimulation of a vesical nerve depend upon at least two factors: muscle tonus and the nature and degree of the anæsthesia. These observations are confirmed and expanded by comparison with the actions of appropriate drugs.
