Followed by a "Theory of Dislocated and Denudated, or Cut 

 Stratified Masses," which is illustrated by fifty-six coloured drawings. 



I do not know why Farey stopped at the Eed Marl in giving an 

 account of Smith's knowledge of the Strata, for Mr. Smith certainly 

 had a knowledge that Coal and the Limestone come underneath. 



At the end of the first volume of Sowerby's Mineral Conchology 

 is a Supplementary Index,^ arranging the shells described therein 

 according to the several strata in which they are found imbedded, 

 from the newest towards the oldest in the British series. The strata 

 referred to are those as classified in Mr. Smith's map. This was 

 kept up in subsequent volumes. 



The Eoyal Society Catalogue contains a list of Mr. Farcy's papers, 

 to which he signed his name, among them are many on music. But 

 there are many anonymous papers of his besides, such as those in 

 the Monthly Magazine. I shall be glad to know if any one can say 

 whether he did not write some of the articles in Eees' Encyclopaedia, 

 e.g. " Grand ridge," " Strata," etc. 



As he was so warm a supporter of Smith, it seems strange that 

 the memoir in the Monthly Magazine contains no reference to his 

 having received his first geological knowledge from him, but, on the 

 contrary, says he obtained his success from following the proposals 

 of the Duke of Bedford. In many of the writings about this date 

 there seems to have been an intentional suppression of reference to 

 Smith in places where it might justly be expected. Can any ex- 

 planation for this be offered ?

 Part 1. 1872. 



THIS Part comprises an elaborate Memoir by Mr. William King, 

 jun., B.A., on the Kadapah and Karnul Formations of the 

 Madras Presidencj-. This series of rocks has been hitherto known 

 by such names as the "Diamond Formation," " Clay Slate Formation," 

 and "Old Eed Sandstone," names which have proved inapplicable, 

 therefore those of the districts they occupy have been applied for the 

 two formations under which the difierent groups of rocks can be 

 classed. Mr. King states there are good grounds for believing 

 that they may eventually turn out to be partly representative of 

 the great Vindhyan series of India, and of a possibly underlying 



^ "For this supplementary index I am (says Sowerby) indebted to my indefatigable 

 friend Mr. John Farey."
