shales and limestones of true Liassic colour and consistency. At these 
points particularly, and along that part of the escarpment hctwoen 
North Cave and South Cliffe, I made diligent search for the " Bone- 
bed," and " Insect-bed," on two consecutive days, without success. 
Neither can I learn, upon full inquiry, that any remains, either of fishes 
or saurians, have ever been found in these pits. Consequently, I con- 
clude, both from my own experience and the testimony of several intelli- 
gent pez'sons, that the Bone-hed, " with bones," does not extend into 
Yorkshire, or, at least, is absent in this locality. Neither was 1 more 
successful in my search for the Insect-heel, though I shoiild not be sur- 
prised to learn, hereafter, that these finely-laminated limestones at the 
bottom of the Hotham Lias, have preserved some insect-remains. I 
was often almost disappointed in cleaving them that no wings occurred 
to me. A more detailed and special examination of this zone by such a 
hand as Mr. Brodio's, might bring to light some hidden treasures ; 
meanwhile I have nothing more to record concerning it. 
The dip of the strata seems very gently eastward, and could bo readily 
estimated with exactness in the roadside-cutting leading to llotham 
village, — a section which deserves attention, both for its stratification 
and its fossils. 
Although the Lower Lias series is present here in great thickness, 
and, possibly, in all its members, yet I have found no means of studying 
any of its zones higher than that of Grrjplmi incurva, till we come to 
the highest of all, where it forms the base of the M:irhtone in the town- 
ship of North Cave. And, excepting a single example of a large 
Pleurotomaria Avglica, dug out of a marl-pit between North Cave and 
llotham, I am scarcely acquainted with any other of its fossils than 
those which I have already enumerated. 
A very great destruction has happened to this formation in and around 
North Cave, reducing the range of hill of which I have been speaking 
to the level of the sandy country on the west, sweeping far away its 
softer constituents, and piling up in great thickness, over limited areas, 
the shattered fragments of its harder limestones in the state of a dis- 
jointed and Avater-worn drift. Thus the northern side of the village of 
North Cave is built upon a thick mass of drift, which at the places 
where I measured was ten feet deep, and almost wholly composed of 
small rounded fragments of fhe " Fosidonomi/a-bed." Similarly, in the 
" Sandy Lane," between North and South Cave, there is an extensive,
