It is valuable as further developing Lambert's theory of terrestrial radiation, and having to some extent anticipated the 

 theories of Dr. Wells {q. v. pu.st), who had however developed his theory of dew quite independently of the above work. 



Both the above copies contain a leaf of r/mfo. which is nearly always wanting.

 Objections qui pourroient s'elever contre ce Systeme: La Theorie des Fluides Elastiques d'apres ce nieme Systtme : 

 Quelques Applications du meme Systenie a certaines Afttnites. This is Le Sage's latest exposition of his hypothesis of 

 extramundane corpuscles, the earliest attempt — after Newton's own — to lind the cause of gravitation. Le Sage's theory 

 was again taken up by Lord Kelvin, in 1871, who declared it would be 'a perfectly obvious consequence of the 

 assumptions were the gravific corpuscles sufficiently small.'
