who care to scrutinize narrowly the surfaces of such lichen-clad 
boulders ; results which also will bear fruits in the aid they will give 
to our geological reading of the phenomena of the Post-Tertiary 
Glacial Age. 
Mr. D, Trowsrince’s Memoir On the Nebular Hypothesis, com- 
menced in No. 114, p. 344, &c., will be read with pleasure by many 
speculative geologists, and is continued in No. 115, for January 
1865, which contains an obituary notice of the lamented founder of 
this Journal. Dr. C. T. Jackson’s account of the Discovery of 
Emery in Chester, Massachusetts, is one of the other articles interest- 
ing to geologists. Mica-schist, soap-stone, talc, talcose slate, granu- 
lar quartz, chlorite-slate, emery (4 feet), chloritoid and margarite, 
magnetic-iron-ore, and hornblende-rock, are the associated rocks 
(metamorphic) in North and South Mountains, Hampden Co., 
Chester, as in Asia Minor. The emery was at first mistaken for iron- 
stone. 
EOLOGY as a Brancu or GENERAL Epucation. An Address 
by Davip Pace, F.R.S.E., F.G.S., &e.—Originally delivered 
to the Glasgow Geological Society, this address now appears as a 
small 8vo. 40 pp. pamphlet. We have only room to quote a para- 
graph :—‘ But while Geology has thus, like other departments of 
natural science, many intellectual inducements to excite, it has also, 
like many others, and much more than most, important economical 
advantages to attract. The rocky crust upon which we dwell is not 
only the great record upon whose tablets are impressed all the former 
phases of our planet—thus binding, as it were, by material attri- 
butes, the living intellect that interprets, with the divinity of Crea- 
tive Thought in the remotest past—but it is, at the same time, the 
foundation of all geographical diversity, the varied habitat of plants 
and animals, the scene of man’s life-labours, the field he cultivates, 
and the sole storehouse of those minerals and metals upon which 
the progress of civilization is so intimately dependent. Geology, 
then, becomes a study of importance to the miner, the engineer, 
architect, farmer, landscape-gardener, painter, geographical explorer, 
and all those whose calling leads them more immediately to deal with 
the internal structure and superficial aspects of our planet. It is 
by no means expected that these men are to make themselves con- 
versant with all the niceties of geological theory, but merely that 
they should learn enough to appreciate the leading deductions of 
the science, and be able to apply them each to his own special re- 
quirements. As science can and must often indeed be studied with- 
out reference to its ultimate applications, so may the practical man 
lay hold of the truths of science, and apply them in an empirical 
way, without being able to work out the problems upon which these 
truths have been founded.’
