Dr. Adams describes the rocks of Bundelcund, taking up the area 



north of that concerning which Dr. Spilsbury 

 1842. Adams. . . 



wrote ; the same nearly as that which was the 



subject of Captain Franklin's paper. He comes to the conclusion that 

 the thickness of the Vindhyan sandstone is small ; he also speculates on 

 the manner of the formation of the limestone seen near Lohargaon, 

 which rock he believes to be of comparatively recent origin. 



Some of the Geologists, whose work we have quoted, pass, as has been 

 shown, from the field of observation to that of speculation, and portions 

 of the rocks of Bundelcund have been referred to the Old Red Sand- 

 stone, to the Lias and to the Trias respectively, as their European equiva- 

 lents. Such hypotheses, quite unsupported as they were by evidence, 

 have naturally proved of little value. Yet having been advanced 

 by men who had at least seen the rocks which they describe, these 

 hypotheses were consistent as far as they go, that is, they group together 

 beds which closely resemble each other, and which are conformably 

 stratified. This can scarcely be asserted of the theories contained in 

 Dr. Carter's* work on the Geology of India. It 

 will perhaps have been remarked that all those 

 Geologists above quoted as having written on the structure of that part 

 of the country with which we are at present concerned, seem almost 

 entirely to avoid all those geological questions which relate to the 

 physical condition of the rock masses : such as the manner of original 

 formation, of subsequent disturbance, of denudation, &c, and also those 

 questions which are concerned with the relations of one series or group 

 of rocks to any other such series, such as the superposition of one of 

 these on another, and the conformity or unconformity of such superposi- 

 tion where it exists ; and thus Dr. Carter unfortunately had not at his 

 disposal that kind of information on the geology of the country which
