INGLEBOROUGH. 
PART VI. THE CARBONIFEROUS ROCKS.

OF GEOLOGY IN THE UNIVERSITY OF CAMBRIDGE.

Introductory. 
" Professor Sedgwick's examinations of the North of England 
have the same date as my own," said Phillips. " We met for 
a few moments near the High Force in 1822 ; after ten years 
of independent research we compared results at Cambridge, 
and I found with great satisfaction that my conclusions, drawn 
chiefly from examining the interior of the district, were con- 
sonant to those of my distinguished friend derived chiefly from 
the western border."* 
Sedgwick, a representative of the ancient race in which 
the blood of the stalwart Scandinavian was mingled with that 
of the Romanised Briton, and Phillips, of the stout hearted 
Silurian stock of South Wales, worked, the one in the land of 
his birth and the other in the land of his adoption, and so bravely 
did they carry their researches into the wild moorlands, and 
so keen their eye and so sound their judgment, that with all 
the help of modern appliances in an opened- up country, we 
can rarely improve upon their field work, except by filling in 
details or altering a bracket ; but they warned us that their 
" lines of division contain much that is arbitrary, and more 
that is merely of local application." 
I shall endeavour, as far as possible, not to introduce into 
this sketch any shibboleths that will make it difficult to refer 
to the descriptions which they have given, though a large pro- 
portion of the fossils have different names from those by which 
they were known when I began to work on Ingleborough. Many 
a student who could do good work and help on the interpretation 
of the phenomena presented to him at every turn in the glorious
