‘Dalmanites Kablike before consigning it to its grave, and then laments 
that Kablikia dyadica must be “degraded” to Kablikia silurica ! 
This result of the “unangenehme Tauschung ” is stolidly described in 
the recently published ‘Sitzungsberichte der natur-wissenschaftliche 
Gesellschaft Isis zu Dresden’ for 1868 (p. 50). We give the page 
because, like the works of Mr. Carlyle’s ‘ Dryasdust,’ the “ Isis” has no 
index. 
All geologists feel themselves participators in some degree in the 
honour which has just been conferred by Her Majesty upon Sir Charles 
Lyell, who has recently been created a baronet of the United Kingdom, 
under the title of Sir Charles Lyell, Baronet, of Kinnordy, in the 
county of Forfar; and we feel certain that the general public is 
equally pleased that this mark of distinction should have been bestowed 
by the Queen upon a savant who has so often and so ably assisted them 
to a clear and philosophical comprehension of geological phenomena 
and their causes.

Ty our last number we gave an outline of the progress of the Ordnance 
Survey of these islands, and we now propose to supplement that sketch 
with an account of the origin and progress of that survey, the object 
of which is to portray on the Ordnance maps the mineral composition 
of the surface. It will be evident, therefore, that a correct topogra- 
phical survey must prevede, and form the basis of, a correct geological 
survey. Now it so happened that a few years after the detailed map- 
ping of the Ordnance surveyors had been commenced in the south of 
England, the value of geological surveys began to be recognized by the 
Government of this country, as well as by those of several Huropean 
states. It was felt that if the area occupied by each geological forma- 
tion, representing, as is generally the case, some special group of 
minerals, could be accurately depicted, by colouring on maps of sufii- 
cient size, we should be able to arrive at an approximate knowledge of 
the mineral resources of the country. In the case of the coal-fields, 
such knowledge would be specially valuable, as forming the basis for 
correct estimates of our coal-resources. But there are other minerals 
and rocks only second in value to coal, such as the iron-formation of 
the Oolitic period, the limestones of the carboniferous, and the slates 
of the Silurian, and it was wisely determined from the commencement 
that in the national survey all formations alike should receive equal 
care and attention, and that the maps should be equally reliable as 
guides for the miner, the agriculturist, or the man of science. 
The Geological Survey of Great Britain had its origin in the 
indomitable perseverance of its first director-general, Sir H. 'T. De la 
Beche. This accomplished naturalist, originally brought up for the 
army, early turned his attention to science, his mind having been pro- 
bably attracted to geology by his residence at Lyme Regis, where the
