" The Messrs. Chambers's Edition of Euclid." 



The Messrs. Chambers have published extensively, under the above 

 title, an " advertisement " in reply to the strictures which were made 

 in the Philosophical Magazine for June, upon Mr. A. Bell's edition 

 of the Elements of Euclid. 



Instead, however, of attempting to show that my censures were 

 either false or unjust, or even more severe than the case actually de- 

 manded, they have attempted to divert public attention from those 

 censures upon the work itself, by making it appear that it was not 

 originally published in contemplation of its being adopted by the 

 Committee of Council ! What answer this may be to the charge of 

 a corrupted text and geometrically -absurd interpolations, I leave to 

 themselves to explain in a future advertisement : but I have to say, 

 once for all, that till they offer some show of justification of their 

 work against these charges, I cannot lend myself to the kind of bye- 

 play in which they are attempting to entangle me. 



As to the insinuation respecting the " animus " of the Review 

 (obviously only another form for the imputation of unworthy motives), 

 I can only say that I have always given the Messrs. Chambers credit 

 for a degree of ingenuousness and discretion which could not stoop 

 to so common-place an artifice. But it seems I misjudged them. 

 I had no motives but those which I plainly avowed, and no personal 

 interests whatever to serve. As a geometer, however, I could not 

 stand by and see Geometry so mangled and mutilated as in the work 

 which the Messrs. Chambers had published (and see it also taken 

 under the patronage of the Government, and enforced upon us at 

 the public expense), without attempting to prove that their work 

 had no claims to such a distinction : and as far as yet appears, my 

 proofs are unassailable on any legitimate principle. It will be time 

 enough for me to think of justifying my strictures when they are 

 met by argument, instead of being parried by merely irrelevant state- 

 ments.
