18 EXISTENCE OF WATER Itf MORIATtC GAS. 



Jnswer. 



Works r«com- With respect to the books my correspondent inauirea 



mended tor the »p _ \ J r . 



study of the after, 1 would recommend, as the first and principal, the 



modem ana- Xraitc du Calcul Diffcrentiel et Integral of Lacroix ; which, 

 with the qualifications he mentions himself as possessing, 

 will be sufficient to give him ft very complete notion of most 

 of the branches of the modem analysis. He should, how- 

 ever, read with great attention, before he begins to look 

 uto the Mtcanique Celeste of La Place, the Traife de 

 JMecanique Eitmentaire of Franeceur, which is an excellent 

 introduction to that work, and the Mecanique Analytique 

 of La Grange, which is a work of the first rank in this de- 

 partment of science. If to these he joins the Thcorie des 

 Fonctions Anaiytiques, and Legons shir le Calcul des 

 Fonctions, by La Grange, he will be able to proceed, with 

 great ease, in any undertaking of this kind, that he may 

 wish to engage in; these being, as I conceive, all the most 

 necessary and useful performances, that have hitherto ap- 

 peare4 on the subject of what is more peculiarly called the 

 modern analysis.
