The sense of hearing is equally blunted, and insensible to ordinary sounds. On several occasions, a person standing behind her has shouted loudly into her ears without exciting the least evidence of being heard. Except upon the conjunctiva, as mentioned, general sensibility seems to be completely in abeyance. Numerous experiments were made to test this fact. For instance, the mucous membranes of the nose and ears were repeatedly tickled with a feather without exciting any reflex contraction; a strong solution of ammonia held under the nose produced no effect. The skin, being less sensitive than the mucous membranes, was pricked with a needle, and a pin thrust through a fold of skin on the hands and forearm; the point of a penknife was also driven into the skin until it bled freely, without producing the faintest muscular contraction or indication of sensibility. A still more decisive test was made with an electro-magnetic battery,[52] the electrodes of which were placed on the front of the forearm where the skin is very thin and sensitive, and the strongest possible current passed through the muscles for more than a minute by the watch without eliciting the least evidence of pain, and the electric brush was equally powerless. The poles were likewise applied to different parts of the face, and violent and prolonged contractions of the facial muscles induced, but without the slightest winking or other sign of sensibility or suffering. Such is the condition of the organic functions during the first part of the ecstasy, but some modifications are observed during the second. Thus, while lying prostrate on the floor, the pulse becomes almost imperceptible, and an ordinary observer would fail to detect it at all, although Dr. Lefebvre was sure it never ceased to beat fully. Its frequency was at the same time greatly increased; so that, when it could be counted, it often rose to 120 or 130 in the minute. The movements of respiration now become more and more feeble, and the closest attention is needed to make sure that they exist, the rhythmical motion of the little shawl that covers her shoulders being often the only appreciable evidence that they are not totally suspended.
