ers an omission is almost a crime. We remember an instance somewhat
to the purpose. After describing Mrs. Dale's tea-party at length, in the
beginning of the book, he wanders off with Crosbie and his sweetheart
on a moonlight-stroll, and so interests us in the feelings of the young
couple, and in Crosbie's plans and promises for the future, (which we
begin faintly to foresee,) that we have forgotten all about the party.
And, indeed, how could the story of the party end better than by gently
passing out of the reader's mind, superseded by a stronger interest, to
which it is merely accessory? But such is not the author's view of the
case. Dropping Crosbie, Lilian, and the more serious objects of our
recent concern, he begins a new line and ends his chapter thus:--"After
that they all went to bed." It recalls the manner of "Harry and Lucy,"
friends of our childhood.

But to return to our starting-point,--in "The Small House at Allington"
Mr. Trollope has outdone his previous efforts. He has used his best
gifts in unwonted fulness. Never before has he described young ladies
and the loves of young ladies in so charming and so natural a fashion.
Never before has he reproduced so faithfully--to say no more--certain
phases of the life and conversation of the youth of the other sex. Never
before has he caught so accurately the speech of our daily feelings,
plots, and passions. He has a habit of writing which is almost a style;
its principal charm is a certain tendency to quaintness; its principal
defect is an excess of words. But we suspect this manner makes easy
writing; in Mr. Trollope's books it certainly makes very easy reading.

_A Class-Book of Chemistry_; in which the Latest Facts and Principles of
the Science are explained and applied to the Arts of Life and the
Phenomena of Nature. A New Edition, entirely rewritten. By EDWARD L.

Though Science has been often vaguely supposed to be something generally
distinct from ordinary knowledge, yet the slightest consideration will
suffice to show us that this is not the case. Scientific knowledge is
only a highly developed form of the common information of ordinary
minds. The specific attribute by which it is distinguished from the
latter is quantitative prevision. Mere prevision is not peculiar to
science. When the school-boy throws a stone into the air, he can predict
its fall as certainly as the astronomer can predict the recurrence
