mains of Plants. In both systems these interpolations thicken 
to the northwards. Thus the nearly undivided mass of lime¬ 
stone under Ingleborough becomes separated into many di¬ 
stinct calcareous beds, with sandstones, shales, and bad coal, 
in Teesdale, Tynedale, and Swaledale, which are still further 
modified by the introduction of coarse pebbly sandstones, and 
workable seams of coal, in the western and northern parts of 
Northumberland:—and the Oolites of Lincolnshire, diminished 
in thickness and debased in purity, are almost lost in several 
hundred feet of sandstone, shale, and coal, which form the 
north-eastern Moorlands of Yorkshire. Mr. Phillips referred 
these interpolations of sandstone, &c. to the originally littoral, 
or perhaps gestuary, situation of those parts of the calcareous 
deposit; while the thicker and more homogeneous limestone 
masses were probably produced under the deeper and more 
tranquil waters of the ancient oceans. The bearing of these 
deductions upon the important subject of the relative form and 
extent of the land and sea in this part of the globe at those 
periods respectively, was briefly illustrated. 
2. The remarkable history of the deposit near Market 
Weighton (first observed by W. H. Dikes, Esq., Curator of 
the Hull Society, and afterwards more completely investigated 
by some of the members of the Yorkshire Philosophical Society), 
in which the bones of several kinds of quadrupeds, including 
species considered as extinct, were found mingled with many 
shells belonging to thirteen existing species of land, marsh, and 
freshwater mollusca, and covered with gravel from the neigh¬ 
bouring hills, together with some larger stones from very di¬ 
stant localities. 
S. The general character of the alluvial deposits, inclosing 
timber and many remains of quadrupeds, in the eastern part of 
Yorkshire, and the peculiar condition of some bones of deer 
obtained by Mr. W. Casson, from the Peat near Thorne. These 
bones appear to have been deprived of a large portion of their 
hardening earth, and are nearly in the state of leather,—quite 
flexible, and much altered from their original shape. 
4. The traces of the action of the atmosphere in the rain 
channels which furrow the sides of the monumental stones of 
Boroughbridge, and form miniature valleys on the broad sur¬ 
faces of the limestone scars on the mountains of Western York¬ 
shire and Westmoreland. 
5. The occurrence of three specimens of unknown scaly 
fishes, with ferns and other fossil plants, in the ironstone bands 
in the lower part of the coal formation of Leeds and Bradford;
