New Geological maps of Great Britain and Ireland. 
We pui'pose making a few remarks^ under tlie above title^ on 
two new/ maps relating to tlie geology of Great Britain^ totally 
dissimilar however m every other particular. Knipe's Geological 
map includes the British Isles_, and is of a large size and most 
elaborate detail, the style of colouring is clear, and the mineral 
deposits are well distinguished, and the whole being on one sheet, 
the continuity and contiguity of strata are well and clearly dis- 
tinguishable. This map contains many of the excellencies of 
former publications — it is not large enough to be cumbersome, 
nor is it too large for the Hbrary wall, and from the inspection 
which we have carefully made we should say that it is decidedly 
a very correct performance, and worthy of an exalted rank in 
the series of geologico-geographical charts. 
The second is a small map in relievo of England and Wales, 
pubhshed by Messrs. Dobbs & Co ; the idea is good, and, so far 
as it goes, is well carried out — of the colouring, too, we cannot 
speak too highly — but the scale is too small to convey any of the 
accuracy which is requisite for the purposes of science, and hence 
its principal utility will be confined to the same limits as other 
geological charts of the same size ; but to those who wish to 
posess a map, giving only the general features of the geology of 
England and Wales, and for beautifying the walls of their li- 
braries, this map will answer every purpose, and it is very mode- 
in price.
