The progress of scientific discovery during the
last fve-and-twenty years, has beenso rapid that
even Acknowledgment general reader may be excused
if he sometimes finds his information in some
particular branch very far behind the received
views Of the time. The vast domain Of physical
science, presenting as it does ever new attrac-
tons to the ardent seeker, has been constantly
explored by many of the best intellects of the
age, and the splendor and importance gof some
of their recent conquests therein will shed new
lustre on the nineteenth century.
Conspicuous among these discoveries must be
ranked those relating to the Inter-action and In
destructibilty of Forces, or as it is now stated,
the Correlation and Conservation of Forces. -
The law8of the Resistance Of Force. which
DR.. Farraday denominates IS the highest in
physical science which our faculties permit us
to perceive y has been made the subject of very
Interesting treatment by Mr.. Herbert Spencer,
whose valuable works have recentlybeen repub-
lshed by the Messrs. Appleton. If We except
the republication of these works and also of the
writings Of. Prot. Tyndall, for which we are in
little has hitherto been done to spread before
the American public the results of 80 much
labor and research. For this reason, the pres
emit volume, which exhibits in q compendions
form the views now received by the best modern
thinkers upon such subjects as Electricity. Light,
Magnetism, The Mechanical Equivalent of Heat,
the laws of Celestial Dynanics, the Forces of In
organic Nature, Sc, &C., will be found of great
value, net only to the general reader, but to all
interested in the matter of education. The
paper on the Relations Of Light and Heat to the
Vital Forces Of Animals, will be found highly in
teresting and suggestive. The manner in which
the rays of the sun are transmitted into muscu-
lar power in the arm of a man, or mental power

great part of his assimilsted food being burned
in hecavities OF the blood vessels to produce it.
This carbon comes to him in various forms; fat,
sugar, the gum of grains supply it. 1t is pre-
pared for him by the intermediate processes of
growth in the plant, digestion in the stomach of
animals and others. 1t is merely the process of
taking and digesting food many times repeated.
The earth eats the sunlight, the plant eats the

We. might make some extracts from these
papers which would be of interest to the readers
ofithe Press, but want of space forbids The
book itself should be in the hands of every
reader. The subjects it treats of are the highest
which can engage the human mind. Tracing
the evolutions and inyolutions of forces, recog-
nizng the fact that matter and force are indie
structible. leads the mind by natural process
toward that "Great First Cause, least under
stood,'' that harmonizes and controls all. The
wiser men ,grow,the more they recognize their
infinite distance from all comprehension of the
boundless range Of that final unknown Cause;
and humility before Hin, keeps pace with our
understanding of His works.
