"The same day a stout, healthy man came to his office suffering from great pain and desiring to have a tooth extracted. Dreading the pain, ho accepted willingly Morton's proposal to use ether, and the tooth was extracted without suffering. Morton reported his success the next day to Jackson, and conversed with him as to the best methods of bringing his discovery to the attention of the medical profession and the public. Jackson pointed out that tooth-pulling was not a sufficient test, as many people claimed to have teeth pulled without pain. It was finally decided that the crucial test lay in a public demonstration in the operating theatre of a hospital in a surgical case." There is one statement in the above to which, according to our rules of literary procedure, we feel obliged to take exception,--that is, the statement concerning the interview between Morton and Jackson after the successful administration of ether to Morton's patient. It is substantially Doctor Jackson's own statement. Doctor Morton gave a wholly different account before the Congressional Committee of 1852. He said: "I went to Doctor Jackson, told him what I had done, and asked him to give me a certificate that ether was harmless in its effects. This he positively refused to do. I then told him I should go to the principal surgeons and have the question thoroughly tried. _I then called on Doctor Warren, who promised me an early opportunity to try the experiment, and soon after I received the invitation...._" Now as these are both _ex parte_ statements, and as there are no witnesses on either side, according to the rule we have already established, they will both have to be eliminated. [Footnote: The Congressional Committee of 1852 did not find Doctor Jackson's report of this interview trustworthy.] Doctor Morton, however, says previously that it was Doctor Hayward with whom he consulted as to the best method of bringing his discovery before the world. In the consideration of this subject we come upon a man of rare character--rare even, in his profession. Dr. John C. Warren was the perfect type of an Anglo-Saxon surgeon. His courage and dexterity were fully equalled by his kindness and sympathy for the patient. Cool and collected in the most trying emergencies, it has been said of him that he never performed a capital operation without feeling a pain in his heart; and the evidence of this was marked upon his face, so that it is even visible in the photographs of him. He deserved to have his portrait painted by Rubens. In 1847 Dr. Mason Warren published a review of etherization, in which he makes this important statement:
