quotations to be forgeries ? No. — Has he demonstrated that 

 Newton never wrote such things either in " words or mean- 

 uig?" No. — But he has immediately afterM-ards told us, on 

 his own authority alone be it observed, that Newton has pub- 

 lished his " Cogitationes" in a way which "affords no pretence 

 to consider them his opinions ;" that is, in plain language, 

 Newton has published as his own thoughts things which he 

 does not believe ! ! ! This discovery of C, so complimentary 

 to the understandings of the rest of the world for the last cen- 

 tury, is a key to the whole. It unquestionably to C.'s ability 



" Exegit monumentum a;rc perennius, 

 Regalique situ Pyramidum altius ; 

 Quod non imber edax, nou Aquilo iuipotens 

 Possit diruere, aut innuiuei'abilis 

 Annorum series, et fuga temporum." 



In fact, it indisputably proves that either Newton or C. knows 

 not what he writes. 



Some pains have been artfully taken by C. to identify D. 

 ■with Mr. Herapath. The reasons he has assigned would just 

 as well suit C. ; since from various parts of his communication 

 lie a})pears fully as well acquainted as D. with " the secret mo- 

 tives of the expressions and omissions," or rather better. Now 

 I never was dexterous myself at unravelling enigmas ; but if I 

 were to argue from the inflammable disposition of Mr. H.'s op- 

 ponent, I should say his name might be deduced from the Latm 

 verb Uro, to burn ; probably it coincides with the imperative 

 mood second person singular, Ure. Should this deduction be 

 correct, the name very much resembles that of Dr. Ure, at 

 Glasgow, of controversial notoriety. Let it be observed I do 

 not positively " ascribe the papers" to Dr. Ure ; but should he 

 not be the author, " he may thuik it worth while publicly to 

 disown them." On the contrary, should my solution of the 

 enigma be correct, he will perhaps, before he again wield his 

 ]iotent pen against Mr. H., favour the world with a lecture on 

 the best method of calculating latent heat *. 



I could now, if I chose, enumerate some curious instances of 

 C.'s adroitness at forgetting his own proposed imaginary ex- 

 jierinients, groundless and unnecessary assertions, ivic. which, 

 when he found the tallies turned against him, he has prudently 

 and silently, but not very gloriously, abandonetl. I could hke-
