VI. MISCELLANEOUS SCIENTIFIC INTELLIGENCE, 
1. On the geological position of oil wells ; by J. P. Lestzy.—In the 
Proceedings of the American Philosophical Society, at page 189, of vol. x, 
Mr. Lesley observes that the recent facts he has collected from the valleys 
of the Sandy, in eastern Kentucky, confirm his view that the oil there 
comes from the base of the Coal Measures; that “the plants of the great 
Conglomerate have been converted into thick oil and reach the surface by 
horizontal drainage over the water-bearing Shales of the False or Lower 
Coal Measures.” The next horizon of oil below this is far down in 
the Devonian. Mr. Lesley also states the fact that Dr, Newberry has 
announced that the flow of oil which took place years ago in southern 
Middle Kentucky came from the Lower Silurian limestones, the same 
horizon that affords oil in limited quantities near Chicago; and that he
