The foregoing record of this meeting was then read, and sanctioned by all concerned. On the motion of Dr. Storer, Voted, That the unanimous thanks of this committee be presented to the gentleman who has submitted himself to the operations of Dr. Collyer this afternoon.

The committee having ascertained from Dr. Collyer that he would expect some public expression from them, after having convinced them at the expense of so much trouble; and after remarks by the Rev. Mr. Gannett, Dr. Greenwood, and A. Peabody, Esq , it was deemed proper to give it, and, After considerable discussion, in which Rev. Messrs. Greenwood, Gannett, Turnbull, Jones, Muzzy, and Chapin, Drs. Storer, Adam, and Flint, and Messrs. Peabody, James, and others took part, the following resolution was adopted unanimously, with a view to its publication - viz.:

Resolved, That while this committee refrain from expressing any decisive opinion as to the science or principle of Animal Magnetism, they freely confess that, in the experiments of Dr. Collyer, certain appearances have been presented which cannot be explained on the supposition of collusion, or by a reference to any physiological principles known to them.

After providing for the publication of this record, the meeting dissolved.

It may perhaps be a satisfaction to some, who respect logical exactness more than random raillery, to examine the following calculation on the doctrine of chances, showing the great improbability of Frederick's guessing correct answers to Mr. Park's questions, as given in the above report. We shall refer to them by their numbers as above given. It will be seen that we omit in our calculation many of the correct answers, just as if in those cases there were no other thing which his mind could be led to fix on for his guess, and therefore it were no guess at all. This, however, is far from true, and it makes a very large concession: 1. In relation to the third answer, suppose (to be within bounds) that only one in four of the buildings in the city has a street on each side of it; and the chances of giving this answer with correctness, in a mere guess, are seen to be one in four, and the ratio of probability is 1-4.

2. On the eighth answer: in what proportion, let it be asked, of all the places within doors can be seen at once seven and more doors - i.e., as many as eight? Probably not one in fifty. Let then the ratio be 1-50.

3. On the tenth answer: suppose that, of all the inner doors in the city, one-twentieth of them are thus barred up at mid-day, and the chances of guessing such a description as the boy did, with correctness, would be only one in twenty; and the ratio of probability in guessing thus, 1-20.

4. On the thirteenth answer: suppose that of all the apartments in the city, the proportion which have in them, between one and two o'clock p.m., Just one person and not more, and that person a man, and not a woman or child, is (we will say, to be within bounds) one in five; and the ratio of probability for one's guessing thus rightly would be 1-5.

5. On the fourteenth answer: suppose that of all the articles that would be likely to attract attention in all the apartments of the city, not more than one in three could be called round, and the ratio of probability is 1-3.

6. On the eighteenth answer: it may be safely said that of the articles in our apartments, not more than one in five could well be thus described in such severe Saxon, and the ratio of probability is 1-5.

7. On the nineteenth: suppose other visible articles in apartments will average as numerous as windows, and then the chances of guessing a window with correctness will be one in two, and the ratio 1-2.

Now multiply all these ratios together - (according to Edin. Encyc., Art. Chances, or Hedge's Logic)

1 X 1 X 1 X 1 X 1 X 1 X 1 = 1

4 50 20 5 3 5 2 600,000, and the chances of guessing correctly in all these instances taken together prove to be only one in more than half a million. Towards making up this number, each of the supposed failures counts only one by way of offset.

We think the estimate we have given of the probabilities in the instances we have selected above is far less than they would bear, to say nothing of the correct answers we have omitted. But unless one can gainsay this estimate as too large, he must admit (600,000 to 1) either that one of our citizens, whom we are accustomed to trust, is duping the public on an extensive and difficult plan, or else that there is something in clairvoyance.

This is not the only case of this kind in which, in order to disprove clairvoyance, it will be necessary to implicate, to a similar certainty - i.e., many thousands to one - the veracity of some of our most respectable citizens. We think therefore the argument grows serious, to say the least.

The twenty-six gentlemen who composed this committee were amongst the most eminent in their respective professions in the United States. No one can therefore but treat such a document with the respect it so justly merits. All were desirous of arriving at the truth. The unanimous decision of less than half the number would consign a human being to death in a trial of murder. It is therefore exceedingly curious that the verdict of twenty-six of the most intelligent men in Boston, U.S., should not be received as conclusive evidence. "There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy."

M. Serres communicated to the Academy the details of several experiments "with ether on rabbits, but as they add little, except in the way of confirmation, to what was stated in the last sitting by M. Gruby, we do not think it necessary to give them here. In direct connexion with this subject, however, we lay before our readers the following letter, which we have received from Mr.
