GLASGOW GEOLOGY.* 
T HIS work consists of a series of sketches and other papers illustrative 
of the geology around Glasgow, based upon notes of excursions, which 
appeared in the local journals from time to time. These have now been care- 
fully revised, and in many parts extended, so as to afford a popular and fairly 
accurate idea of the geological structure and of the principal features of 
interest which the rocks of the district present. 
Within the area described, as shown by the accompanying geological map, 
the chief strata are of Palaeozoic age, with their contemporaneous and intrusive 
igneous rocks, covered, however, in many places by a considerable thickness of 
post-tertiary deposits, formed during the glacial period, the effects of which, 
and the accumulations resulting therefrom, are fully explained in some of the 
chapters. In the other chapters are described the various subdivisions and 
characters of the Old Red Sandstone and Carboniferous series, the latter of 
which with the associated volcanic lavas and ashes form so important a fea- 
ture of the geology around Glasgow. 
This series of excursion-sketches, with the intercalated historical notices, 
now issued in a collected form, will be an especially useful guide to those 
interested in Geology who may pay a passing visit to the district. 
THE MICROS C OPE .f 
D R. CARPENTER’S manual of the microscope is so well known, that 
we need hardly do more than call the reader’s attention to the pub- 
lication of a new and enlarged edition, the sixth that has appeared. The 
book has now increased to some nine hundred pages, and, judging from an 
inspection of its contents, the veteran author has used every endeavour to 
render it as complete as possible. T plan of the work continues exactly 
the same as in former editions, but an immense quantity of new information 
has been put into it, both in the portion relating to the microscopic investi- 
gation of plants and animals, and in that treating of the structure and use of 
the microscope and its accessories, and the preparation of objects for exami-
