50 FIFTY YEARS GEOLOGICAL RESEARCH IN THE BRISTOL DISTRICT. 
of the Rhaetic section at Pylle Hill, Totterdown, 1 was published 
in 1 89 1. Wilson also during this period published valuable lists 
of the fossil types in the Bristol Museum 2 (1890), and in the Bath 
Museum 3 (1892), and in collaboration with W. H. Hudleston 
their 'Catalogue of British Jurassic Gasteropoda' (1892). The 
preparation of this Catalogue which includes 147 pages must have 
involved an immense amount of labour. 
Considerable attention was paid during this decade to the ques- 
tion of the origin of the well-known Cotham or Landscape Marble, 
this being the subject of papers by B. Thompson 4 (1894), and 
H.B.Woodward 5 (1892 and 1898). 
Mr. E. B. Wether ed continued his study of the lithology of the 
local sedimentary rocks, his papers ' On the occurrence of the 
genus Gii"vanella in oolitic rocks . . . ,6 (1890), ' On the 
Inferior Oolite of the Cotteswold Hills with special reference to its 
microscopical structure' 7 (1891), and 'On the formation of 
Oolite' 8 (1895) au * deal with the question of the origin of oolitic 
structure. 
The meeting of the British Association at Bristol in 1898 was 
directly responsible for two most valuable comprehensive accounts 
of Bristol geology, Mr. W. H. Hudleston's presidential address 
to Section C, and Prof. Lloyd Morgan's ' Geological History of 
the Neighbourhood of Bristol,' published in the British Associa- 
tion Handbook. Mr. Hudleston's address is mainly a critical 
account of the advances in the study of local geology since the 
previous meeting of the British Association at Bristol in 1875, 
and the publication of the Survey Memoir on the district in 1876. 
Prof. Lloyd Morgan's admirably concise and graphically written 
chapter has been the foundation on which all subsequent accounts 
of local geology have been based. 
1900-1912. 
During the latter part of the preceding decade E. Wilson had 
been engaged with the aid of a grant from the British Association 
on the study of a bone-cave at Uphill. This work was continued 
by his successor as Curator of the Museum, Mr. H. Bolton. 9 Apart 
from w r ork at Uphill, not much has been done during recent times 
in the study of the Bone-Caves of the Bristol district, but Mr.
