some of these rocks have been so altered that their original 
source is scarcely, if at all recognizable. How this earth-heat has 
raised the strata, thus formed beneath the sea, above the waters 
of the ocean, has been pointed out; and the action of the sea- 
waves, and of rain and rivers in carving out the face of the coun- 
try, horizontally and vertically, has been indicated. In tracing 
the chain of causation from the well-known to the Unknow- 
able, I have not followed the example set by Prof. Huxley 
in the excellent little book which bears the same title as this 
article. In these days, however, when we hear so much of the 
“pride of Science,” it is well to point out that in the study of 
Nature we reach at last ultimate questions, with respect to which 
we must one andall confess with modest humility that we are and 
must be ignorant. Finally, in making each fact the effect of one 
which had gone before it, in time, and the cause of one which fol- 
lowed, I have aimed at that organization of knowledge, without 
which any number of accumulated facts are but isolated pieces 
of general information— Geological Magazine.

BREHM’S ANIMAL Lire.'\—The third volume of this interesting 
series, which is to comprise in all ten large octavo volumes, 1s at 
hand, and perhaps the present one is as valuable and entertaining 
as any, since it treats of the horses and Ruminants, and the seals 
and Cetacea. There are one hundred and twenty wood-cuts of 
the same general excellence as those which appear in this notice, - 
and there are besides twenty-one full-page plates; those of the 
Shetland pony, zebra, ibex, jak, stag, bison, rhinoceros, wild boar 
and sea lions being especially attractive, and apparently faithful 
studies by the most eminent German zodlogical artists. Among 
the wood-cuts the antelopes, elands, spring-bock, hartebeest and 
their allies, are well rendered. The figures that we have selected 
are fair examples of the artistic work. The American reader will 
find that some of the characteristic ruminants of his country are 
well drawn, as in the Rocky Mountain sheep (Fig. 1), and the 
musk ox (Fig. 2), The hippopotamus is well drawn, especially 
_ its head and face, and its skeleton (Fig. 3.) is represented, while 
oe the account of it by Dr. Brehm is detailed and fresh. The
