It was alluded to in the conversation between Dr. Morton and Mr. Metcalf in the early summer of 1846, hereafter referred to.

Mr. James T. Hodge, a geologist and chemist of rising reputation, known to Dr. Jackson, inhaled sulphuric ether, as an antidote to chlorine gas, in 1844, on the advice of Prof. Ellett, who treated it simply as the established prescription.

R. H. Dana, Jr., Esq.

Dear Sir,-In the summer of 1844 I was so unfortunate as to inhale a strong draught of chlorine at my laboratory in N. York, by which I was rendered speechless for several hours. While in this condition, Prof. Ellett, of the chemical department in the college at Columbia, S. C., happening to call upon me, advised my inhaling sulphuric ether as an antidote, which I did with great relief, though not to the point of producing insensibility. Yours truly, JAMES T. HODGE.

Boston, February 8, 1848.

Dr. Warren, on Etherization, (pp. 2, 85, 86, and 87,) shows that the inhaling of ether has been in repute, in Europe and America, for more than fifty years, for relief in cases of pains, inflammations, and spasms. See, also, British and Foreign Review, April, 1847.

Dr. Warren, again, (p. 86,) says, "Monsieur Ducos, in Paris, performed some remarkable experiments with ether on animals early in the last year; an account of which is given in the Paris Med. Gazette of March, 1846. In these experiments were exhibited most of the phenomena which have since been witnessed in the human body."

We think, then, it may be stated, in justice to all parties, that the following things were known before the discovery in question, viz.:

1. That the inhalation of ether would produce insensibility.

2. The idea of producing insensibility, by inhalation, for the prevention or mitigation of pain in surgical operations, had been presented on high authority.

3. Experiments had been made for this purpose, but not satisfactorily, with nitrous oxide gas, with vegetable decoctions, and with various narcotics; and books had been published on the subject.

4. Inhalation of ether, as an antidote to chlorine gas, and in various cases of pain, spasms, &c., temporary or chronic, was an established prescription.

On the other hand, it was NOT KNOWN, that the insensibility produced by inhaling ether was of such a character and degree, and governed by such laws, as to be of great value in the most painful operations.

What remained to be proved was, in fact, a problem of three parts.

1. The degree to which this insensibility could be carried.

3. The use this state could be put to, in cases of painful operations.

Robert Collyer tried experiments in Boston, in 1843, to produce insensibility by the inhalation of the vapors of narcotics and stimulants, and published a work on the subject.

In the autumn of 1844, Dr. Horace Wells of Hartford, Conn., came to Boston and performed an

It will be observed that these are things which could be demonstrated only by actual experiment. This was a case in which scientific deductions, notions, or hypotheses, could discover nothing, establish nothing. It is one of those discoveries which are made by courageous, persevering men; and for which no extraordinary degree of scientific attainment is necessary.

II. What is the specific thing that makes this a discovery?

Bearing in mind, then, that since Davy's time no claim as discoverer can be allowed for merely suggesting or experimenting upon the idea of producing insensibility by inhalation, and that it was known to physiologists that the inhaling of ether would safely produce a considerable degree of insensibility, and was useful in cases of pains and spasms, we will proceed to trace the history of the discovery of this hitherto hidden law.

CHAPTER II.

FACTS AGREED FACTS IN DISPUTE-DR. JACKSON's

It is fortunate for the parties and the public that the time and place of the only conversation relied upon, have been fixed by each claimant, without dispute or possibility of change.

The main facts in controversy are these:Dr. Jackson claims to have discovered, previously to his interview with Dr. Morton, this wonderful property of ether; admitting, however, that he had never actually tried an experiment to test it by any painful operation. He claims to have communicated this discovery to Dr. Morton at the interview, and that Dr. Morton, in his experiments at his office and at the hospital, was only his (Dr. J.'s) agent or instrument; that these were, in fact, his own experiments, upon the maxim, qui facit per alium facit per se. In confirmation of this, he al|leges that Dr. Morton had no intention of experimenting, in this direction, and was utterly ignorant of sulphuric ether, and that he first put it into his mind to try an actual experiment, and predicted the result that has followed. So entire is Dr. Jackson's claim of foreknowledge that in his pamphlet 1. That on the 30th Sept., 1846, Dr. W. T.

CLAIM DR. MORTON'S CLAIM.

In conducting the examination of a disputed question, one of the first steps should be to settle what facts are admitted on both sides, and what are in dispute. The following facts may be considered as admitted, on both sides :

2. Neither Dr. Jackson nor any one in his behalf was present at this experiment.

3. The next day, Dr. Morton called on Dr. Jackson, and told him what he had done; which was the first information Dr. Jackson had that such an experiment had been performed.

Dr. Morton, on the other hand, says, that ever since Dr. Wells' attempt in 1844-45, his attention had been at times turned in this direction; that he had made experiments of inhaling gases and mixtures, and, particularly, that he had tried ethers, and sulphuric ether, in the summer of 1846, that he had read somewhat and made inquiries as to the properties of ethers; that when he went to Dr. Jackson he was in the course of a

CHARLES T. JACKSON, M. D.

Dr. Morton was, for a while, in partnership with Dr. Horace Wells, but this connection was dissolved, and Dr. Wells established himself in Hartford, Conn. In December, 1844, Dr. Wells came to Boston, and requested Dr. Morton to introduce him to the officers of the Medical College, in order that he might make some remarks, and try his experiment to produce insensibility by the inhalation of nitrous oxide gas.

Dr. Warren on Etherization, (p. 85,) cited ante, says, "Sir Humphrey Davy himself successfully employed the inhalation of nitrous oxide for the relief of pain. In this country, Dr. Horace Wells, of Connecticut, made many trials of this gas in 1844. In the autumn of that year he came to Boston, and, in company with Dr. Morton, visited me at the Medical College, for the purpose of requesting that the medical class should have an opportunity of hearing some remarks on the use of the nitrous oxide for the prevention of pain. These remarks were actually made, and at a subsequent day a trial of the gas took place."

This trial was the extraction of a tooth. Dr. Morton was present. Dr. Wells, in his pamphlet, admits this to have been a failure. Dr. Wells does not profess to have tried, or made any allusion to, the use of ether, at this time.

Dr. Morton, in his memoir to the French Academy, says, that after this experiment his mind was frequently directed to this subject, and that he

judgment of every reader, raises a fair presumption
in favor of the truth of this statement.
known that Dr. Morton has given unusual atten-
tion to the branch of mechanical dentistry, that is,
the business of preparing and fitting sets of artificial
teeth. This requires the extraction of several teeth
at once, usually a very painful operation : one which
deters many persons from undergoing it, and obliges
many to abandon the attempt after having entered
upon it. This is especially the case with delicate
females. Thus, Dr. Morton had a direct pecuniary
motive, bearing almost daily upon him, to alleviate
or annihilate pain under his operations. Probably
no man has had this motive pressing upon his pe-
cuniary interests more than the mechanical dentist.
The operations of the surgeon are necessary, and
are seldom performed until they are inevitable.
Those of the mechanical dentist are voluntary with
the patient, mostly mere matter of greater or less
convenience, of luxury or appearance.
This is
probably the reason why Dr. Wells, whose occu-
pation had also been chiefly mechanical dentistry,
rather than any man of science or of the learned
professions, took up this subject in 1844.

As it is unnecessary to offer formal proof of notorious facts, it may be stated here that Dr. Wells, soon after the experiment of 1844, gave up dentistry, and was employed variously, part of the time in preparing and exhibiting a collection of birds, and afterwards as an agent for the sale of shower baths. And, still later, he went to Europe to purchase pictures for resale in this country; he was there engaged in this enterprise, when he put in his claim to this discovery; and remained in the same business until his death, in January, 1848.

We will now present the evidence on the point, that Dr. Morton did experiment upon this subject, and for this end, in the summer of 1846, some

son.

That this was connected with the unsuccessful experiment of Dr. Wells, to produce insensibility by nitrous oxide gas.

And, lastly, that Dr. Morton could not have been utterly ignorant of suphuric ether and its effects on the 30th of September following.

Can there be a doubt that, at this time, Dr. Morton at least had in his mind the idea, that the result which Dr. Wells failed to produce by nitrous oxide, might be produced by sulphuric ether?

Metcalf, it is unnecessary to make any remark to a Boston public. But for the information of persons at a distance we make the following extract from the report of the trustees of the Massachusetts General Hospital, who say that in his professional capacity "he has long possessed, in the highest degree, the confidence and respect of the medical profession; and there is no one in the community whose personal character would give higher authority to any statement of facts distinctly and positively made." Mr. Theodore Metcalf-in a note to Dr. Morton, dated Dec. 20, 1847-says, "I can only state, that I remember to have met you at Mr. Burnett's store early in the summer of 1846, and to have had a conversation with you in regard to the medicinal qualities of sulphuric ether, a quantity of which you were then purchasing. I cannot, as you desire, give the precise date, but know it to have been previous to July 6, as I left Boston on that day for a tour, from which I have but a few weeks returned." Mr. Metcalf also, subsequently, sent the following letter.

BOSTON, Jan. 26, 1848.

Sir-In answer to your inquiry respecting the nature of my interview with Mr. Morton, I can only add to my note of December 20, that the conversation was commenced by some inquiry on his part, concerning the nature and effects of sulphuric ether,

a vial of which he then held in his hand.

In answer to his several questions, I gave him such information as he could have obtained from any intelligent apothecary at that time, and also related to him some personal experience as to its use as a substitute for the nitrous oxide; adding the then generally received opinion, that its excessive inhalation would produce dangerous, if not fatal consequences. Some reference was made-but whether by Mr. Morton or myself, I cannot remember-to the unsuccessful experiments of his former partner, Mr. Wells, with the nitrous oxide. It was one of those casual conversations which quickly pass from the mind; and it was for the first time recalled to my memory, upon seeing, months after, in a French journal, an account of the anesthetic effects of ether, the discovery of which was ascribed by the writer to a Boston dentist.

I am, sir, very respectfully,
your obedient servant,
THEODORE METCALF.

N. I. Bowditch, Esq.
Mr. Metcalf sailed for Europe July 6, 1846, in
the ship Joshua Bates, and was absent, on a tour,
until shortly before writing the above letters. This
accounts for so material evidence having been de-
layed, and Dr. Morton says that he had forgotten
having held any such conversation until reminded
of it by Mr. Metcalf, after his return.

In offering the deposition of Mr. Francis Whitman, we make the following extracts from the trustees' report. And we remark, once for all, that when we thus present vouchers for the character of any witness, it must be understood that we do it for the information of persons to whom he is a

stranger.

"Francis Whitman, one of these deponents, has recently died; his truthfulness seems to be unquestionable." And again, "Whitman, whose character even Dr. Gay admitted to have been above suspicion." The certificates to the character of Mr. Whitman, in the place where he was born and passed his childhood and early youth, and where his family is of high standing and worth, are couched in the strongest terms, and are from persons holding public offices of trust and honor.

That I have often heard Dr. Morton speak about discovering some means of extracting teeth without pain. This discovery appeared to be the subject of his thoughts and investigations during the greater part of last year, i. e., 1846. One day-I think it was previous to July, 1846-Dr. M., in speaking of the improvements he had made in his profession, and of some one improvement in particular, said, if he could only extract teeth without pain, he "would make a stir." I replied, that I hardly thought it could be done. He said, he believed it could, and that he would find out something yet to accomplish his purpose. In conversation with Dr. M., some time in July, he spoke of having his patients come in at one door, having all their teeth extracted without pain and without knowing it, and then going into the next room, and having a full set put in.

I recollect Dr. Morton came into the office one day in great glee, and exclaimed, that he had "found it," and that he could extract teeth without pain! I don't recollect what followed; but, soon after, he wanted one of us in the office to try it, and he then in and have an experiment tried upon him. After sent William and Thomas out to hire a man to come all these circumstances happened, Dr. Hayden advised Dr. Morton to consult with some chemist in This evidence puts the date, fortunately, beyond relation to this discovery. I went, at Dr. Morton's all question; and it may be considered as estab-request, to see if Dr. Jackson had returned, (he lishing these facts; viz. : having been absent from the city,) but found that he was still absent.
