FIFTY YEARS GEOLOGICAL RESEARCH IN THE BRISTOL DISTRICT. 49 
of Portishead' 1 (1885), ' Bristol Building Stones' 2 (1886), ' The 
Mendips, a Geological Reverie ' 3 (1887). 
Mr. S. S. Buckman's far-reaching work on the geology and 
palaeontology of the Jurassic rocks of the South- West of England, 
began during this period. His papers on 'Some species of 
Brachiopods from the Inferior Oolite of the Cotteswolds ' 4 (1886). 
'On the Cotteswold, Midford and Yeovil Sands' 5 (1889), and 
' On the Relations of Dundry with the Dorset, Somerset and 
Cotteswold areas' 6 belong to this decade. E. Witchell anrl W. 
C. Lucy were also at this time active workers on the Oolite rocks of 
the Cotteswolds. 
Allusion must be made to two important papers on fossil fish by 
J. W. Davis, viz., ' On the Fish Remains of the Bone Bed at Aust 
near Bristol ' 7 (1881), and ' On the fossil fish of the Carboniferous 
Limestone of Great Britain' 8 (1883). A very large proportion 
of the teeth and spines figured in the 65 plates accompanying this 
memoir come from the Avon quarries. 
1890-1899. 
The chief papers published during this decade were by workers 
who were already active during the preceding one. 
H. B. Woodward's long study of the Jurassic rocks culminated 
in the publication in 1893 of ms Memoir on the Lias of England 
and Wales, and in 1894 of the companion volume on the Lowei 
Oolitic Rocks of England. Both these memoirs are all important 
to Bristol geologists. Much other valuable work on the Jurassic 
and Rhaetic rocks of the district was done by Edward Wilson and 
Mr. S. S. Buckman who were joint authors in 1896 of a paper on 
' Dundry Hill, its upper portion, or the beds marked as Inferior 
Oolite in the map of the Geological Survev ' 9 ; Mr. Buckman's 
paper on ' The Bajocian of the Mid-Cotteswold ' 10 (1895) in 
which the remarkable non-sequential succession of the oolitic 
rocks was described and shown to be due to contemporaneous 
erosion, belongs to this decade, as also a paper on ' The Bajocian 
of the Sherborne District' 11 (1893) ; this paper contains a com- 
parison with the rocks of Dundry. E. Wilson's careful account
