departments of Geology, Mineralogy, CiystallograpLy, &c. The balance of 
the proceeds of the Wollaston Donation Fund has been awarded to M. J. 
Bosquet, of Maestricht, in aid of the valuable researches on the tertiary and 
cretaceous moUusca, entomostraca, and other fossils of Holland and Belgium, 
on which he has been so long and so successfully engaged. 
Time occupied hy Denudation in Scotland. — In a paper lately read before 
the Geological Society of Glasgow, Mr. James Geikie alluded to the 
immense period of time which must have been occupied during the 
process of denudation which occurred in Scotland. In concluding an 
important paper by stating that an enormous amount of time must 
have been required for even the broader effects of denudation, he asked, 
How many long ages had rolled away since these islands rose above 
the level of the Arctic Sea, in which our marine drifts were amassed, and 
yet, during all that time, how little change had come upon them at the 
instance of the atmospheric forces ? And if the records of the old Arctic 
condition — the delicate ice-markings on the rocks, the loose incoherent 
deposits on the hill-slopes and plains — still remained so perfect, notwith- 
standing the ceaseless activity of the denuding agents — ^if the mere skin, as 
it were, and surface-markings of the land were still so largely retained, 
what should we say to the time required for the growth of that covering 
itself, and for the production of these strange ice-mouldings and flutings, — 
and how, above all, could we apprehend (for comprehend we could not) the 
truly tremendous lapse of time, during which the solid land was gradually 
sculptured into hills and valleys by the rains and frosts and rivers of the 
past? 
The Formation of Siliceous Minerals. — Mr. John Buskin continues his 
paper on this subject in the Geological Magazine for January, and illustrates 
his description by very handsomely executed plates. As we said in a former 
notice of Mr. Buskin’s labours, we think they show too much of the ex 
cathedra character. Mr. Buskin comes before the scientific world with very 
little claims to its patience or consideration, and displays a tone and manner 
which are best summed up in the vulgar expression ^-bumptious.” He 
never gives himself the least trouble to discuss the views of men whose 
whole lives have been devoted to the subject in hand, and who have brought 
to its investigation a knowledge of physical and natural science which Mr. 
Buskin is far from possessing. This is to be regretted, both because it is 
unjust to other workers, and because it prevents even whatever intrinsic 
merit there may be in Mr. Buskin’s opinions receiving recognition. Mr. 
Buskin’s doctrines of political economy, as expressed in that desperatelj'’ 
dogmatic essay, “ Unto this last ” have been simply smiled at by unbiassed 
thinkers, and, unless we very much mistake, his notions on mineral segrega- 
tion will meet with a similar fate. In his last paper he describes five varie- 
ties of silica: jasper, flint, chalcedony, opal, and hyalite 5 and alludes to 
two varieties of mineral constitutions, pisolitic and reniform. 
Flint Implements of the Yorhshire Wolds. — At a meeting of the Archaeolo- 
gical Institute on Feb. 7th, Mr. Evans called attention to a fine collection 
of these relics, which were then exhibited on the tables. The collection was 
a most varied one, and exhibited every form of flint instrument, knives, 
saws, arrow-heads, curved knives, chisels, &c. Sir John Lubbock, who also
