amongst them to desert the higher 
grounds on which they have been lifted 
up, and to descend to their normal alti- 
tudes : in both cases, however, the pre- 
sent summits will display the same fea- 
ture, namely, utter desolation.” — Pp.

The following passage draws attention 
to the connection between the various 
branches of science. 
“ W e are too apt to draw a line of 
imaginary demarcation between the 
sciences, as though each had its own 
propositions to establish, and nothing 
more ; indeed, some of us would appear 
to assume (though perhaps tacitly) that 
what is proved to be true in one depart- 
ment may be, at least, rendered incon- 
sistent (if not actually negatived) in ano- 
ther : but surely this requires no argu- 
ment to refute, since a principle which is 
true, is true under every circumstance 
and condition, for otherwise, it could be 
both true and false. We need not, 
therefore, be afraid of comparing truth 
with truth, under whatever shape it may 
arrive, as though it were possible that 
either of its phases could ever suffer from 
the ordeal of a close contact, since, if 
they be really true and free from decep- 
tion they must needs go hand in hand, 
and may become (however opposite they 
be in their subjects) directly explanatory 
of each other. The astronomer who is 
not intimately acquainted with pure ma- 
thematical analysis in its various aspects 
and bearings is, in fact, no astronomer at 
all. The geologist who would interpret 
the grand phenomena of the earth’s 
crust apart from statical and dynamical 
knowledge, and without the help which 
the chemist, mineralogist, anatomist, 
zoologist, and botanist, can afford him, 
stands a fair chance of leaving his prob- 
lems unsolved, whilst the students of zoo- 
logy and botany who would endeavour 
to understand and account for what they 
see in the animal and vegetable worlds 
around them, without calling in geology 
to their aid, must assuredly be prepared 
to fail signally in their attempts. All 
indeed must work in concert, if the whole 
is to be advanced, — and not only in con- 
cert, but as mutually assisting each other. 
By the help of truths already known, 
more may be discovered ; for those in- 
ferences which arise from the application 
of general truths to the particular things 
and cases contained under them, must be 
just.”— Pp. 155, 156. 
As a good analogy of the gradual 
awakening of our perceptions to minute 
specific distinctions where at first all ap- 
pears exactly the same, we quote the fol- 
lowing : — 
“ The Alpine range, when seen from 
afar, appears a monotonous mass of a 
dull uniform hue; and nothing, of all 
the wondrous details which it includes, 
can be distinguished, except perchance 
the outline of their jagged peaks pro- 
jected in faint relief against the distant 
sky. One by one, however, as we ap- 
proach it, inequalities present them- 
selves; the surface, which lately seemed 
so uniform and grey that it could be 
compared only to a cloud, is found to be 
cleft by ravines ; and valleys, in all their 
magnificence and breadth, expand slowly 
to our view. Yet, marvellous as is the 
change, this is not all : wood and water, 
without which the landscape would be 
barren, are in turn revealed ; whilst the 
play of light and shade upon the moun- 
tain-slopes proclaims at length that the 
picture is well nigh complete. Still 
more to be disclosed, does in reality re- 
main : and we must advance nearer yet 
if we would either fully realise the w'hole, 
or enter into the surprising minutiae of 
each of its component parts. And so it 
is with the objects we have been just dis- 
cussing. When contemplated in a mass, 
and by an uneducated eye, hosts of them 
may appear lobe identical; but as our 
vision becomes clearer and more acute, 
differences, formerly inappreciable, are 
gradually made manifest, — until at last
