I' BELIEVE I need not enter into any proof, that the 



theory, which makes Basalt a volcanic production, and once 



tiuid lava, was invented by Mf. Desmarest ; the friends, as 



weir as the enemies, of this opinion, are unanimous in 



ascribing it to him alone. Dr. Hamilton (Lett. I. Part II.) 



calls him, the ingenious father of the Volcanic Theory; and 



Mr. Raspe says, " if it deserves any praise to have first 



" hit on a lucky hypothesis, it cannot possibly be denied to 



" Mr. Desmarest;" and Mr. Kirwan, while he combats the 



opinion, calls Mr. Desmarest, the father of the Volcanic 



Theory.
