The Popular Science Monthly" is always vel.
come, but the February isiue Is especially attrac
tive Politicians abound with us, but If we have
any thinkers on political science they will be
deeply interested in the first article Of this num-
ber by Herbert Spencer, en- Political Diferen
tiation," He is tIacil 6 the early development OF
political institutions and in this chapter he euc'-
dates the growth Of those class distinctions which
form so large part Of the constitution Of civilized
societies. Those who inquire into the modes Of
getting rid OF social diversiies had better look a
little into the causes which brought them about.
The second article, by B. Taylor. + R, s. is on
the "ohRin Of the Plow and Wheel Carriage" 1t
is ITOiusely illustrated, and contains much curl
ious information on the arcf @ology Of these ia
miliar machines The second article, on "Dlet,"
by DR., Felix l.. Oswald, in his series on Physical
Education" deals with simulants and all kinds
Of irrltants and provOcstives which are come to
be so extensively employed with proper foods
The article is iulltof valuable suggestions point
edy presented and the writer gives no quarter to
what hei denominates the poison habit. Next
comes the paper by Sir George ". Cox on. Horses

Engines" is extremely interesting. It is copious.

iOiency and economy Of all those smaller ma.
chimes driven by gas and electricity which are
available for light work. Mr., William A. Eddy
devotes a brief article to "The Value Of Accom-.
plishments," In which he forclbly illustrates the
important social principle, that taking vast gen
eral average higher tsses lessen the action of the
lower, and he explains how the interest In &C
complishments becomes tributary to solid i'm
provement, There is next an elaborate and rich

sCribing the recent remarkable discoveries O.
