"Sir Thomas, however," he went on, "was much opposed to our union, on the ground of some real or fancied social disparity in our positions; but I at last obtained his conditional consent, if only I could succeed in obtaining the Fellowship of the Royal Society, which might, he thought, be accepted as a passport into that fashionable circle of which he was a member. Spurred on by this ambition, and by the encouragement of my Amelia, I worked day and night at the perfectioning of my great discovery, which I was assured would bring not only honour and dignity to myself, but also the alleviation and assuagement of pain to countless thousands of my fellow-creatures. I concealed the nature of my experiments, however, lest any rival investigator should enter the field with me prematurely, and share the credit to which I alone was really entitled. For some months I was successful in my efforts at concealment; but in March of this year--I mistake; of the year 1781, I should say--an unfortunate circumstance caused me to take special and exceptional precautions against intrusion. "I was then conducting my experiments upon living animals, and especially upon the extirpation of certain painful internal diseases to which they are subject. I had a number of suffering cats in my laboratory, which I had treated with pausodyne, and stretched out on boards for the purpose of removing the tumours with which they were afflicted. I had no doubt that in this manner, while directly benefiting the animal creation, I should indirectly obtain the necessary skill to operate successfully upon human beings in similar circumstances. Already I had completely cured several cats without any pain whatsoever, and I was anxious to proceed to the human subject. Walking one morning in the Strand, I found a beggar woman outside a gin-shop, quite drunk, with a small, ill-clad child by her side, suffering the most excruciating torments from a perfectly remediable cause. I induced the mother to accompany me to my laboratory, and there I treated the poor little creature with pausodyne, and began to operate upon her with perfect confidence of success.
