A EH^TIG SECTION AT REDLAND. lOl 
In the same bed occur two or three layers of crushed 
shells (principally Cardium rhceticum), amongst which are 
some fragments of beetle wings, mostly small and difficult 
to determine. One form, however, is in very fair conditioD, 
and has caused some discussion among the entomologists, 
some considering it a larval form of a Lampyrid beetle, while 
others think it is a pupa case of one of the Libellulidse. 
There does not appear to be any definite ^' bone bed," as at 
Aust Cliff, but teeth and scales of fish are scattered through 
the section. At some horizons they are more plentiful than 
at others, but bones are scarce, and when found, are usually 
very small. 
The bed " N " of Gotham Marble is the best development 
the writer has seen of this curious rock, many hundreds of 
blocks having been unearthed. The thickness is unusual 
(varying from 4 inches to 11 inches) — about double the average 
measurement. Many of the larger blocks have double "land- 
scapes." Some of these have been polished with very 
satisfactory results, the rest have been used for road making ! 
There is not room in this paper to enter into the question 
of the origin of this remarkable rock, but the writer would 
like to mention that after seeing many hundreds of blocks, 
both in situ and loose, he has been unable to find any 
evidence in favoar of the " dendritic " theory, while there is 
equally little to support the " pressure " theory advanced by 
some writers. Altogether, the paper written by Mr. Beeby 
Thompson {Q.J.G.S., August, 1894) appears to more nearly 
fit the facts than any of the other solutions offered. 
Near this section the writer was fortunate in finding a 
small deposit of the rare mineral known as " Baryto- 
Celestine." This mineral was first noticed by a former 
member of the Bristol Naturalists' Society, Dr. Norman 
Collie, who contributed a paper on the subject to the Society's
