In another part of the same publication Professor Simpson has another list of cases, all equally favorable. In some of these the labors were protracted _many hours_, and in others, operations with instruments were performed, of the most terrible character, such as would, under ordinary circumstances, have been attended with the most horrible suffering. As this article gives an instance of nearly every kind of delivery under the influence of chloroform, and contains also some admirable reflections upon its employment, I quote it in order to make the present account complete. CASE 2.--Seen with Mr. Carmichael; a second labor; she began the chloroform inhalation before the dilatation of the os uteri was entirely completed; the child was expelled in fifty minutes afterwards. I kept her under the chloroform for a quarter of an hour, till the placenta was removed, the binder applied, and the body and bed-clothes were arranged and adjusted. On awaking she declared that she had been sleeping refreshingly; she was quite unaware that the child was born, till she suddenly heard it crying at its first toilet in the next room. An hour afterwards she declared she felt perfectly unfatigued, and not as if she had borne a child at all. In her first or preceding confinement she had been in severe labor for twenty hours, followed by flooding. No hæmorrhage on the present occasion. CASE 3.--Patient unmarried; a first labor; twins; the first child presented by the pelvis, the second with the hand and head. The chloroform was exhibited when the os uteri was nearly fully dilated; the passages speedily became greatly relaxed, (as has happened in other cases placed under its full influence,) and in a few pains the first child was born, assisted by traction. I broke the membranes of the second, pushed up the hand, and secured the more complete presentation of the head; three pains expelled the child. The mother was then bound up, her clothes were changed, and she was lifted into another bed; during all this time she slept soundly on, and for a full hour afterwards, the chloroform acting in this as in other cases of its prolonged employment, as a soporific. The patient recollected nothing from the time of the first inhalations, and was greatly distressed when not one but two living children were brought in by the nurse to her. Dr. Christison, who was anxious to observe the effect of the chloroform upon the uterus, went along with me to this patient.
