A temple was erected on the spot, and dedicated "to Apollo. The particular apartment of the oracle was immediately over the "chasm from which the vapours issued. A priestess delivered the responses -"she sat upon a tripod or three-legged stool, perforated with holes over the seat "of the vapours. The condition of the priestess was identical with that "of the mesmerized person.'

Though I performed a great many minor operations during a condition "induced by the inhaling of the stimulating vapours, I was at that time pre"judiced in favour of that induced by the nervo-vital fluid from a second person in the mesmeric state; during which condition I had seen a great many "capital operations performed without pain to the patient.

Again, at page 32, in explaining the feats of the Egyptian magicians, I use "these words: - 'The only difference between my experiments and those "mentioned by Lane in his admirable work on Egypt is, that in my case, the "boy's brain was rendered sentient to the mental image by the nervous agency "from a second person; whereas the boys used by the Egyptian magi were "caused to inhale narcotic fumes, producing in both instances the identical state of brain.'

In Louisiana, in 1839, I reduced a dislocation of the hip-joint of a man, who "was rendered insensible by the inhalation of vapour arising from rum. It is "a very common practice among the negroes to inhale these fumes, and thereby "produce total unconsciousness. It must be taken into consideration that my "experiments were not performed in a corner, but before the world, and in the "very city where Drs. Jackson and Morton reside, and that I have explicitly "demonstrated that whenever the brain was the seat of special action, the ner"vous force was robbed from all parts of the body in order to meet the increased "demand of the brain. The lungs are the manufacturing organs of the system " - they supply the wasted powers - their function being particularly in action "during sleep; whenever any stimulating vapour is applied to them, their pro"ductive function is much increased. This is the case in the inhalation of "ether, alcohol, protoxide of nitrogen, or any other stimulating vapour. In "1835 I was a student at the London University College. Dr. Turner, Pro"feasor of Chemistry, used to administer to those pupils of his class who chose "to inhale it, the laughing or protoxide of nitrogen gas. On one occasion the gas "gave out, and sulphuric ether was substituted.

Mr. Belmain, Dr. Turner's "assistant, will no doubt remember my having inhaled the ether, and how long "I remained in the laboratory in an insensible state, and which will never be "forgotten by me. Now is it likely that when engaged in the investigation of "this subject in 1842, I purposely neglected the experience I had bought "in 1835? In fine, I have shown clearly that Drs. Morton and Jackson got "the idea from Dr. Wells, a gentleman I never heard of, but who must have "heard of my experiments in connexion with inhalation, or as they were face"tiously called 'the bowl of molasses' experiments;' for there was no editor in "the United States who had not a joke at my expense, in connexion with my "experiments.

I remain, most respectfully yours,

To which are added the licence of the President of the Municipal Council of Saltillo.

It was in the Sierra Madre Mountains on the 31st of July, 1849, that I was "attacked by the banditti of twenty-three, who took from me my effects, together with the documents referred to in the letter to the Critic of April, 1847. The original of the Mexican official document is now in my possession.

The following from Dr. Henry Bennet, shows how Mr. Wells fulfilled his promise.

Mentone, October 31st, 1868. "My deaR DR. CollyeR,

I have no recollection of having received any further documents from Mr. "Wells after the publication of my letter in the Lancet in 1847. Indeed I think "I may safely say that I did not again hear from him on that or any other " subject. I am not mistaken, his death occurred not long afterwards. Trusting you will succeed in establishing your position, of which fact, however, I do not doubt,

Faithfully yours,

HenRy BenNet."

Ten months subsequent, Horace Wells committed suicide in New York.

It must be conclusive evidence, that had either Wells or Morton been engaged in the investigation of producing an anaesthetic state prior to their haphazard, accidental trials, their researches would have been made known. Not a scrap of the kind has ever been adduced. Mr. Morton was so ignorant of the chemical nature of sulphuric ether, that when he went to Dr. Charles Jackson he said, "What kind of looking stuff is it?" Dr. Jackson was most unlikely to suggest its use as a substitute for the protoxide of nitrous gas, he never dreamt that it would produce an anaesthetic state; in fine, we have his and Morton's conjoint affidavit to the effect that neither himself or Morton knew or "believed the same to have ever been known or used before.
