Dr. Williamson, reports an interesting and remarkable case, in which he saved the life of an infant in convulsions, by the use of chloroform. He commenced the use of it at nine o'clock one evening, at which period the chiid was rapidly sinking, numerous remedies having been already tried without effect. He dropped half a drachm of chloroform into a thin muslin handkerchief, and held it about an inch from the infant's face. In about two minutes the convulsions gave way, and the child fell into a sleep. By slightly releasing the child from the influence of the chloro form, he was able to administer food by which the child was nourished and strengthened. The chloroform was continually administered in the manner described, from Friday evening at nine o'clock until Monday morning at nine. This treatment lasted sixty hours, and sixteen ounces of chloroform were used. Dr. Williamson says he has no doubt that the chloroform was instrumental in saving the infant's life; and that no injurious effects, however trivial, from the treatment adopted, have subsequently appeared.
