gate, a magnificent and very clean-cut channel being seen at 
Deepdale Firs. Professor Kendall pointed out in the Haugham 
channel that as the channel curved, one side was steep and 
the other a gentle slope, thus presenting the appearance of the 
banks of a large stream, as in the case of Welton Vale, and the 
same kind of thing was afterwards seen at Swaby. For the 
steep sides he proposed to use a term suggested by Mr. J. 
Lomas — the " turnpool " — and the sloping side he called the 
" strand." At Swaby large mounds of morainic matter had 
been deposited. 
The meeting was resumed at the King's Head Hotel on 
Tuesday, April 25th, when Dr. A. Smith Woodward, F.R.S., 
President of the Geologists' Association, expressed the pleasure 
it had given the members of that Association to co-operate 
with the Yorkshire Society, and take part in their General 
Meeting. Mr. Stather suitably responded. The Hon. Secre- 
tary read a paper by Mr. J. R. Mortimer, of Driffield, on " The 
Genesis of the Yorkshire Chalk," which was followed by an 
interesting discussion, in which Messrs. W. Whitaker, P. F. 
Kendall, A. Smith Woodward, A. H. Davis, and W. L. Carter 
took part. A vote of thanks to the chairman concluded the 
meeting. 
On Wednesday the party drove to Market Rasen, in order 
to further examine the Neocomian deposits and the Kimmeridge 
Clay. The descent of the Cretaceous escarpment near Willingham 
presented opportunities for the examination of exposures of 
Red Chalk, Tealby Limestone, and Spilsby Sandstone, the 
Tealby Limestone containing examples of Pecten cinctus and 
Exogyra sinuata, the same fossils as were found when the party 
visited the Tealby Clay at Donington-on-Bain brick-pit. The 
famous exposure of the Kimmeridge Clay was visited. The 
fossils here are in exquisite preservation, the most common 
being Astarte, Nucula, Corbula, Thracia, Trigonia, Inoceramus, 
Area, Cerithium, Neritopsis, and many species of Ammonites. 
the last-named generally displaying a rich nacreous lustre, 
The party also drove to Claxby to examine the old ironstone 
workings along the escarpment, and separated with many fehcita- 
tions on the interesting and enjoyable united excursion.
