(See Therapeutics, below.) It is not properto push the drug until the muscular relaxation amounts to completeflaccidity, as this endangers the respiration. Nekvous System.—In producing its effects, ether acts first onthe brain, then on the sensory tracts of the spinal cord, then on themotor tracts, then on the sensory side of the medulla oblongata, andfinally upon the motor side of the medulla, and thereby producesdeath from respiratory failure if given to excess. Upon the nervetrunks it exerts no effect unless it is directly applied to them. Etherdoes not produce anesthesia by influencing the blood, coagulating theprotoplasm of the
