15033 [STENSEN, Latine] STENO (Nicolas) The PRODROMUS to a DISSERTATION concerning

 Accompt both of the Frame and the several Changes of the MASSE of the EARTH, as also of the

 first Secretary to the Royal Society], with folding copperplate, 16mo. fine copy in hf. C//(RARE), 

 1. 10s j. Winter, 1871 



The English translation of this important work, which laid the foundation of crystallography and stratigraphy, and 

 contains a theory of the earth which makes him the first of ' Neptunists,' was published only two years after the 

 appearance of the Latin original printed in Florence. The translator was unknown both to Halkett and Laing and Watt. 



' His genius is most apparent in his geological works ; in those few smaller treatises, for example, in which his casual 

 observations of the soil of Tuscany, the quality of the earth's strata, their relative position and the fossils they contain 

 lead him to nothing less than the foundation of the modern science of Geology. Steno was the first to demonstrate that 

 non-fossiliferous layers were the most ancient, that the layers consisting of marine sediment were originally circumscribed 

 by even, horizontal planes etc. etc., and finally he was the first to describe in detail the forms and manner of formation of 

 crystals, showing that opposite sides were parallel, and many other matters of a like nature.'
