13. Her first labour; in her thirty-ninth year; very severe expulsive pains for nine hours; the last hour, owing to the size of the head and the contracted outlet, no progress was made; and beginning to get exhausted, it was decided to apply the forceps, which were accordingly sent for, but a few minutes before they arrived, nature had overcome the difficulty; the child was born alive, but with a large caput succedaneum, showing how firmly it had been retained the last hour. 14. Had always had great suffering in her former labours; used the Inhaler about three hours; breech presentation; placenta was adherent, and required great force to peel it off. I have thus given the results of my experience with an agent calculated, under proper management, I venture to think, to be of great service in the practice of midwifery. I believe my experience with it has proved that-- 1st. It is possible for a woman to be delivered with less pain from the beginning to the end of her labour than a rhubarb draught would occasion. 2nd. It is possible to afford that relief without interfering with the regular and natural action of the heart or brain. 3rd. It is possible for the child to be born without the mother experiencing any pain whatever, while at the same time she retains her consciousness and power to bear down when told to do so; and her first knowledge of the birth of her child shall be from hearing it cry. 4th. That when a woman is delivered without suffering pain, although she shall have had inflammation after each of six previous labours, the prevention of the suffering will have the effect of preventing the usual inflammation. 5th. That by preventing the suffering of labour, the woman does not lose her strength, and always has a speedy recovery. CASES. _Of the following Letters from Patients which I have selected for publication, six relate to cases of first labour._ It is generally admitted that the suffering of first labours equals, if not surpasses, that of subsequent ones. In three of these six labours there was the additional drawback of age, the youngest being more than twenty-eight years old. In one of these cases also there was a contracted outlet, which retained the head for one hour. It follows, therefore, that if in the severer cases of labour, with obstacles to impede delivery, women can be so fully relieved as not to suffer pain, the more ordinary and milder cases will also have the same relief. I, therefore, think it unnecessary to give any larger number of cases.
