initely more important than all the
speculative knowledge which we can obtain by means of sciences
the most solid. This ought to lead wise men to make their
sciences _the exercise and not the occupation of their mental
powers_. Men are not born to employ all their time in measuring
lines, in considering the various movements of matter: their
minds are too great, and their life too short, their time too
precious, to be so engrossed; but they are born to be just,
equitable, and prudent, in all their thoughts, their actions,
their business; to these things they ought especially to train
and discipline themselves."

So, young friends, bring _Brains_ to your work, and mix everything with
them, and them with everything. _Arma virumque_, tools and a man to use
them. Stir up, direct, and give free scope to Sir Joshua's "_that_," and
try again, and again; and look, _oculo intento, acie acerrima_. Looking
is a voluntary act,--it is the man within coming to the window; seeing
is a state,--passive and receptive, and, at the best, little more than
registrative.

with. We could not wish a fitter present for a young man starting on the
game of life. It is a wise, cheerful manly, and warm-hearted discourse
on the words of Bacon,--"He that is wise, let him pursue some desire or
other: for he that doth not affect some one thing in chief, unto him all
things are distasteful and tedious." We will not spoil this little
volume by giving any account of it. Let our readers get it, and read it.
The extracts from his Thesis, _De Mentis Exercitatione et Felicitate
exinde derivanda_, are very curious--showing the native vigor and bent
of his mind, and indicating also, at once the identity and the growth of
his thoughts during the lapse of thirty-three years.

We give the last paragraph, the sense and the filial affection of which
are alike admirable. Having mentioned to his hearers that they saw in
himself a living illustration of the truth of his position, that
happiness is a necessary result of knowled
