coiiiiiioiiplace. It had. too, been further refined by the recogni- 
tion of zonal successions in the great homogeneous formations, 
the Jias being the subject of the first essay. This work, well begun 
by Oppel, Quenstedt and other continental geologists, was 
finding new applications in England. 
It was a great advance, and it led to great extensions of the 
knowledge of the Lias of Yorkshire. 
Stratigraphical Geology had made such strides th^it no new 
formation has been discovered since 1859. Everything from the 
Cambrian to the Alluvium was known, and had been placed in 
its proper sequence. An immense impetus had been given to 
this branch by the foundation of the Geological Survey, at first 
in a tentative form, when it was decided to employ certain 
gentlemen to colour Ordnance Maps with an indication of the 
Geology, that was how their function was described, and Sir 
Henry de la Beche was given the direction of the work. From 
then till now it has passed under the control of a great variety 
of Government departments, and the Board of Agriculture is at 
present the over-ruling authorit}^ The Survey of Yorkshire had 
not })een begun in 1859, which was perhaps a fortunate circum- 
stance, as the surveyors would not at that time have had the 
inestimable advantage of the splendid six-inch maps contoured 
for every twenty-five feet of height, that this favoured county now 
enio3''s along with Lancashire. 
To the Yorkshire geologist of to-day these maps and the 
accurate and detailed mapping of the Geological Survey are as 
daily bread, and none realises more fuUy than myself how great 
a part they have played in stimulating and aiding original research. 
The country has reason to be proud of the unrivalled achieve- 
ments of a branch of the public service that receives ver}^ in- 
adequate support from the Treasury, and we in Yorkshire may 
congratulate ourselves upon the possession of some of its finest 
products. 
Descriptive and systematic Palaeontology was already 
secured from neglect by the foundation of the Palaeontographical 
Society, that year by year from 1848 has published magnificent 
monographs on British fossils, and its valuable acti\4ty still con- 
tinues.
