The General Meeting was held at the Fleece Hotel, under 
the presidency of Robert BeU Turton, Esq., of Kildale HaU.. 
Mr. Isaac Hodges, of Normanton, was elected a member. After 
an address by the Chairman, he proposed a sympathetic resolu- 
tion with the family of the late Mr. William Ackroyd, F.I.C.^ 
F.C.S., of Halifax, formerly a member of the Council of the 
Society. The deep regret of the Society at this serious loss to 
its membership was also expressed by the Hon. Secretary, and 
carried by the members rising. 
Professor KendaU, F.G.S., then delivered an address on 
" Problems in the Physical History of the Cleveland Area." 
The rocks of Cleveland are bent into an arch or antichne, the 
ridge of which runs from Carlton to Robin Hood's Bay. This 
arch produced westwards is continued in an anticline just north 
of the vaUey of the Swale. There was an arching of the Millstone 
Grit and older rocks between the valleys of the Tees and Swale 
before Permian times, and the Millstone Grit was worn off before 
the Permian rocks were laid down. There was a further move- 
ment along this line in post -Permian times. Again at the close 
of the Lias there was another movement sharpening the same 
arch. In most places the Dogger, the lowest beds of the Oolites,, 
lies upon the Upper Lias. 
Notwithstanding this, in some areas L'pper and Lower 
Lias fossils have been found in the Dogger, showing that in 
some unknown area there must have been a very extensive 
denudation of the Lias prior to, or during, the deposition of 
the Dogger. In some areas, however, the Dogger entirely 
disappears, seeming to show contemporaneous erosion. The 
Coxwold-Gilling Gap is due to the letting down of a narrow 
strip of rock by two parallel faults, which can be traced across, 
the vale of York as far as the Ure, but then are lost below thick 
drift deposits. These faults seem to be part of a system of 
faults that runs across Malham to Ingleton, continued by those 
bounding the Vale of Eden, and again by the Tyne faults which 
run to sea at Tynemouth. This system of faults in the Vale 
of Eden and North Yorkshire shows movement in Carboniferous 
and Post-Carboniferous times, but cannot be proved to have 
moved again until subsequent to the Kimmeridge Clay period.
