ser. 3, vol. xii. pp. 277-286, woodcut. 



The grahamite is an altered asphalt similar to other " coal " deposits 



in the Huasteca " coalfield." They all occur in connexion with a 



fossiliferous shale, at first supposed Cretaceous but now Tertiary. The 



Cristo Mine deposit is described. Analyses are given. G. A. L.

Announces the stratigraphical divisions established in the field, and 

 their relation to the Palaeozoic subdivisions of New York and the 

 Mississippi basin. In passing westward the entire series, from the 

 Coal Measures to the Potsdam beds inclusive, thickens from 1000 to 

 32,000 feet. Near Battle Mountain an Archaean land-mass rose to the 

 "W. of the Palaeozoic ocean. No trace of unconformity has been detected 

 between any of the members of the series. The following are the sub- 

 divisions in ascending order : — 1. A great series of quartzites and argil- 

 lites with Primordial fossils at top, about 12,000 feet thick, Cambrian. 

 2. The Ute limestone, 2000 feet, with fossils of the Quebec group. 3. 

 The Ogden Quartzite, 1000 feet. 4. The Wahsatch Limestone, 7000 

 feet, including Devonian, Subcarboniferous, and L. Coal Measures. 5. 

 The Weber Quartzite, 6000 feet, representing the Middle Coal Measures. 

 6. U. Coal Measures, 2000 feet. 7. Permian or Permo-carboniferous, 

 500 feet. G. A. L.

The more important uplift of these ranges took place at the close of 

 the Cretaceous and not of the Jurassic period, as was stated in the
