ARTICLE VI. — On some points in American Geology. By 

 T. Sterry Hunt, F.R.S., of the Geological Survey of Canada. 



{From the American Journal of Science No. 93, 1861.) 



The recent publication of two important volumes on American 

 geology seems to afford a fitting occasion for reviewing some 

 questions connected with the progress of geological science, and 

 with the history of the older rock formations of North America, 

 The first of these works is the third volume of the Palaeontology 

 of New York by James Hall ; we shall not attempt the task of 

 noticing the continuation of this author's labors iu the study of 

 organic remains, labors which have by common consent placed 

 him at the head of American palaeontologists, but we have to 

 call attention to the introduction to this 3rd volume, where in about 

 a hundred pages Mr. Hall gives us a clear and admirable summary 

 of the principal facts in the geology of the United States and 

 Canada, followed bv some theoretical notions on the formation of 

 mountain chains, metamorphism and volcanic phenomena, where 

 these questions are discussed from a point of view which we conceive 

 to be of the greatest importance for the future of geological sci- 

 ence. A publication of this introduction in a separate form, with 

 some additions, would we think be most acceptable to the scientific 

 public.
