ers, who kindly lent them for the occasion. Mr. W. II. Wyles 
(the Clerk to the Commissioners), and Mr. W. W. Harry (the 
engineer) afforded the party every facihty in the examination of 
the specimens. Whilst the company were thus engaged, Dr 
OHver, who is well known as the author of a valuable work on 
" Harrogate Waters," appeared at the wells and supplemented the 
President's observations. Dr. Oliver dwelt more especially upon 
the geological conditions under which the water finds it way to 
the surface in connection with the very remarkable anticlinal 
which is known to exist at Low Harrogate. The singular strati- 
graphy of Harrogate arrested the attention of geologists a long 
time ago. Mr. Wm. Smith, the father of English geology, was 
the first to appreciate the peculiarity, but although he reco^> nized 
that there was an anticlinal or upthrust of lower rocks, extending 
from Harlow Hill to Lower Harrogate, he appeals to have thought 
that within that anticlinal there was a synclinal basin towards 
which the springs gravitated. Later on, his nephew, the late 
Professor Phillips, who for forty years had given great considera- 
tion to the peculiarities of the geology of Harrogate, drew the 
attention of the Geological Society of London to the very remark- 
able features of the district, the diflficulties in regard to which had 
been to some extent clear ed up during the making of the new rail- 
way across the stray. The subject of the anticlinal was treated 
generally in a diagram in the paper brought before the Geological 
Society by Professor Phillips, and the relation of the millstone 
grit beds to the north and south of the Yoredale rocks beneath 
was made very clear. At the same time Professor Phillips seems 
to have had a notion that there was a sort of synclinal towards 
the apex of the anticlinal, and his section at this part of the 
diagram is somewhat obscure and dii^icult to comprehend. 
When the party left the Old Sulphur Wells they proceeded to 
verify the stratigi-aphical facts in connection with the anticlinal, and 
for this purpose walked to the well-known road-stone quarry in the 
Cold Bath Road. This stone is one of the hard beds of the Yore-
