At first, for a short time, there may be some vascular excitement; within an hour, and especially after the continued use of the drug, the arterial sedation is accomplished, and may last for several hours. The central organ is also quieted, and thus we obtain a diminution of blood in the nervous centres, as well as elsewhere, modifying the activity of their functions.
