would no longer fupprefs this Method of 

 his, and feveral other things he has, efpe- 

 daily relating to his Differential Calculus, but 

 rather, as foon as his Leifure permits, pub- 

 lifh them for the Good of the Common- 

 wealth of Learning. In the mean while we 

 hope the Illuftrious Marquefs Be PHofpital 

 will fpeedily make publick what is neceflary 

 to perfect that Calculus, in the latter part 

 of that excellent Work of his, which (in 

 the Preface to the former part) he informs 

 us, he has compos'd upon the Integral Calcu- 

 lus. We expecYalfo, with fome Impatience, 

 that other Section, in which that Noble 

 Author promifes he will (hew the Ufe of 

 his Calculus in Phyfickj and Mechanicks. For 

 whatever he has publifh'd, as well thofe 

 Specimen to be found fcatter'd in the Lif-

 Book of his (Intitul'd, Analyfe des Infiniment

Whereas the Ingenious Mr. J. Bernouilli has 

 thought fit (in the Ads of February and Au- 

 guft, An. 1695.) to fay my Method is not 

 General, I freely confefs it, as that Saga- 

 cious Perfon might ealily perceive in the 

 Courfe of my Examples. In a Matter fa 

 Intricate I took what Steps I could ; and if 

 d^ter'd with the length and difficulty of the 

 Journey, I then made no farther Progrefs. 

 I might fairly make a Step where I pleafe, 

 fince my Application to thefe Mathemati- 

 cal Studies. is only by the by. Mr. Bernouilli 

 has partly hinted where my Method is at a 

 S3 Stand,
