tioned line is found, were such as immediately to suggest the idea, that the leaf which follows it must be one that was reprinted after the original had been cancelled. The binding of a book may sometimes give material information concerning its internal structure; and on appealing to it, we found that the teaf (p. 199. 200.) in what is called the second edition, is not in continuity with any other leaf of the book, though firmly attached to them by glue. It is therefore a leaf reprinted after the cancel of the former.

A fact equally in favour of the hypothesis, that there was no new impression, is, that the errata in your two editions are precisely the same, and that even the same table of them is found at the end. The table, indeed, might have been kept through negligence, though the errata were in fact corrected. This, however, is not the case ; for if


any erratum from the table, you will find, on looking up the place, that it is carefully preserved in the new edition. This, it inust be confessed, is quite unaccountable, if the editions are ially different. The first thing that the printer does, un si, work is to undergo a new impression, : " Luiscct the errata that have been discovered, in the copy to be printed from; and this is so plain a dictate of common sense, that we cannot, in any instance, suppose it to have been neglected.

Still, however, before your readers have a right to form a decided opinion, it behoves them to weigh the evidence on opposite sides, and to consider on which it preponderates. Against the hypothesis, we have the disect testimony of the author himself, a man of character and education, and holding a respectable rauk in society : in favour of it, we have the curious combination of circuinstances just stated, which, if taken by itself, would amount to a probability falling short of certainty by a quantity incalculably small. Every man must determine for himself what opinion be is to form, and will naturally adopt the supposition he thinks least wonderful. We have stated the evidence fairly as it appears to us: the task of drawing the conclusion, we leave to those who may be supposed more impartial judges.

It remains for us, Sir, to mention some examples, the same precisely in both editions of your work, where propositions and demonstrations are borrowed, without acknowledgment, from authors that have not yet been mentioned. One of the most remarkable of these is a proposition given at page 409, &c. of your first volume, constituting two articles, and containing a very beautiful theory of the whirlpool formed by water flowing through a horizontal aperture, and impelled at the same time by some external force. No reference is here made to any book whatsoever; and the reader, of course, is left to ascribe to yourself the whole merit of this elegant investigation. The truth however is, that it is taken, word for word, from Venturi, as translated in Nicholson's Journal, vol. III. 4to. p. 13. The investigation of the proposition is so elegant, and the result to which it leads so simple, that there was great demerit in concealing the name of the author, and great weakness in supposing that it could be concealed. None but a mathematician of the first order could reasonably hope to pass for the author.


Another instance in which you have appropriated the works of a learned foreigner, relates to the same subject, (the issuing of water from a hole in the bottom or side of a vessel), and extends from about the middle of page 412. to page 419. of your first volume, which is translated with very little variation from the Architecture Hydraulique of Prony, vol. I. p. 358. to p. 365. You have not, however, mentioned the name of Prony, but have referred to Bossut, and the select Exercises at the end of Dr Hutton's Conics. The student who turns to these last, will find the subject of effluent water treated of in a manner different from yours, and less elegant; but if he look at Prony, he will find the same investigation which he admired in your book, the very same figure, and nearly the same denominations.

In your second volume, you have given an account of Coulomb's Experiments on Friction, and the Stiffness of Cords ; and you will please to remember, that you were very much offended with us for supposing (which indeed we did not do)

had borrowed this from Dr Brewster, We have, however, a charge to bring against you as heavy as that would have been, and one, of which we should perhaps at this moment have been ignorant, if your heat and intemperance had not forced us to make a stricter examination.

The greater part of the account just mentioned is so far from being drawn up by yourself, from the study of Coulomb's Meinoir, that literally translated from the abridgement of that memoir given by Prony, in the first volume of his Architecture Hydraulique. From s 33. page 92. of your second volume, to the end of page 43, the whole, with the exception of a sentence here and there, is translated from the work just mentioned, page 504 to page 513; of which, however, you have made no mention. You may allege, perhaps, in your defence, that there is no great harm in all this, because both Prony and yourself were professedly giving an account of the experiments and reasonings of another persons and indeed we will most readily acknowledge, that your readers have no reason to complain that you them Prony's Digest of these important experiments, instead of your own. You certainly could do nothing so good as to give

that you


have given

that which is actually contained in your book, provided you had acknowledged from whence you had taken it, and had not left your reader to give you the credit of a work which you had not performed.

But enough on a subject, in itself disagreeable, and on which nothing but the necessity of repelling your violent and abusive attack could have induced us to enter. Knowing, as you did, how vulnerable you were, not only at the points to which our inquiry has happened to be directed, but, in all human probability, at many more, we cannot commend the prudence that ventured to provoke the present investigation ; but must certainly admire the boldness that, in such circumstances, could request of the editor of the Edinburgh Review, that his love of truth and justice would • induce him to state, in No. xxvii., that the note of which you

complained was erroneous throughout.' With this request we have now so far complied, that we have corrected the errors of that note, to the best of our ability: we have put the public in possession of the facts on which the judgment given in it was founded; and willingly take leave of a subject which no consideration shall induce us to resume.

We have the honour to be,
Sir, your very obedient Servants,
