In the conversion of energy in'the body certain acid waste products are formed which are eliminated by the liver, kidneys and lungs. The blood is thus kept alkaline, in Avhich condition only is the carriage of oxygen to the tissues possible. If the production of adrenalin, the secretion of the ad- renal glands, be prevented, either by removal of these glands, by cutting the nerves which supply them or by narcotizing the latter Avith morphin, activity is reduced. On the other hand administration of adrenalin produces results similar to.
