I went yesterday to St. George's Hospital to see the chloroform tried. A boy two years and a half old was cut for a stone. He was put to sleep in a minute; the stone was so large and the bladder so contracted, the operator could not get hold of it, and the operation lasted above twenty minutes, with repeated probings by different instruments; the chloroform was applied from time to time, and the child never exhibited the slightest sign of consciousness, and it was exactly the same as operating on a dead body. A curious example was shown of what is called the _Ètiquette_ of the profession. The operator (whose name I forget) could not extract the stone, so at last he handed the instrument to Keate, who is the finest operator possible, and he got hold of the stone. When he announced that he had done so, the first man begged to have the forceps back that he might draw it out, and it was transferred to him; but in taking it he let go the stone, and the whole thing had to be done over again. It was accomplished, but not of course without increasing the local inflammation, and endangering the life of the child. I asked Keate why, when he had got hold of the stone, he did not draw it out. He said the other man's 'dignity' would have been hurt if he had not been allowed to complete what he had begun! I have no words to express my admiration for this invention, which is the greatest blessing ever bestowed on mankind, and the inventor of it the greatest of benefactors, whose memory ought to be venerated by countless millions for ages yet to come. All the great discoveries of science sink into insignificance when compared with this. It is a great privilege to have lived in the times which saw the production of steam, of electricity, and now of ether--that is, of the development and application of them to human purposes, to the multiplication of enjoyments and the mitigation of pain. But wonderful as are the powers and the feats of the steam-engine and the electric telegraph, the chloroform far transcends them all in its beneficent and consolatory operations.
