CONCHO LOGY. 



parts of the surface of all Europe, and tlic Mountains, of 

 which they form very often a material and substantial part, 

 are evidently of a different shape externally to all others that 

 we are acquainted with. The arrangement of form, and the 

 shape of their summits is always alluvial or rounded, and 

 waved with gently undulated lines, as every soft and pulpy 

 mass would naturally be when operated upon by a fluid, 

 and by a successive agitation of the waters of the ocean. 



This idea suggests itself to the mind upon examining 

 the d iff rent forms of the Mountains of Portsdown, and the 

 chalk hills which are so remarkable in the Southern coun- 

 tries and the internal part of England, which latter have 

 inclined ., and dipping strata of rock, and which may be 

 supposed to possess their primaeval form. 



These immense Masses of chalk, according to this 

 theory, may be considered as nothing more than the alluvial 

 remains of som^ violent agitation of the waters of the ocean, 

 and fcrhich will be more fully explained in deductions drawn 

 from a full survey of the facts which nature presents to our 

 view. 



Remarks on the English Fossils. 



IN the Fossil Reliqua? found at Willsden, Middle- 

 sex, the shells were remarkable for their form, and the 

 fewness of the number which were found j and they were 

 inclosed in a very solid stratum of steatite or soap rock, 

 subsistent to bed gravel and flint stones. Several fragments 

 of carbonaceous black wood of a fibrous texture were found 

 with them, and several pieces of glassy scoria and lava t 

 which were filled in part with air bubbles, and had evidently 

 been at some former period in a state of fusion. Tb«
