place, as shewn by Mr. Smith’s “ Map of the Strata/* 
published by Mr. Cary, (as correctly as the want of 
bearings and distances, &c. in so many instances would 
now permit of being done,) and the species and varieties 
of shells at each place* with references to the plates and 
figures in Min. Conch. 
Conceiving your excellent work, to be contributing in 
a very eminent degree to the solid advancement of 
geological knowledge, I am very desirous to see it pro- 
ceed more rapidly, by appearing Monthly ; and I hope, 
not only that your present subscribers would approve 
this change, but that many new subscribers from amongst 
liberal and well-informed land-owners, and country 
Gentlemen and Ladies, would be attracted, by such an 
announcement of more speedy publication.— Wishing 
every success to your useful undertakings, for promoting 
a more intimate acquaintance with the works of the 
all- wise and beneficent Creator, 
I remain. 
Your obedient humble servant, 
JOHN FAHEY, Sen**
