received, to Inquiries in our last Volume, respecting Mr, 
Michell and Mr. Vofield’s Geological Manuscripts, Sc. 
By Mr. Joun Farey, Sen., Mineralogical Surveyor. -—

To Mr. Tilloch. 
Sir, i my Report on the Agriculture and Minerals of 
Derbyshire, the first volume of which, treating of the sur- 
face, minerals, rivers, &c. is now in the press, An alpha- 
betical List of the most remarkable Mountains, Hills and 
Eminences has been printed, referring to a small Map of 
41 principal Ridges, or ranges of high ground, called water- 
heads, which divide the drainages to 32 rivers and rivulets, 
‘in and near Derbyshire. By a series of numbers, placed 
on or near to each ridge in the Map, the situation of the 
several hills, peaks, tors, cliffs, banks, edges, tops, heads, 
stones, lows, or other highest or otherwise remarkable and 
elevated points of the surface, are pointed out; and their situ- 
aticn, with respect to the Towns, is mentioned, and the 
stratum on the top of each hill in the List; the mines, 
quarries, caverns, &c. on them are also noticed, in some 
instances. At the conclusion of the printing of this part 
of my Report, it occurred to me, that a List of the Hills and 
their upper strata, in the order in which they are numbered 
on the several ridges, would be not less useful, than the 
alphabetical one above mentioned, particularly to Residents, 
and to Geological Travellers when on the spot, on which 
account I have sent you such a List, -in case you deem it 
worthy of a place in your Philosophical and Geological 
Magazine, and in which case, you may perhaps, at a future 
time, give a copy of the Map of Ridges, on which these 
numbers are found. 
It may be proper here to remark, that I found it neces- 
sary, in three instances, to deviate from the plan of naming 
the Ridges by the river-districts, or drainages which they 
bound, viz. the Grund Ridge extending front near Saddle- 
worth on the Huddersfield Canal in Yorkshire, to. near 
Harecastle on the Trent and Mersey Canal in Staffordshire : 
the Ashby and Burton Ridge, extending nearly from one 
of these towns to the other in Leicestershire and Stafford - 
shire, across an angle or corner of. Derbyshire; and the 
Charnwood Ridge, extending from Mount Sorrel to Thrings-
