Mr. Worsley-Benison has been discussing this question in a very
interesting way, and he says in conclusion that "_physiologically_ the
most distinctive feature of plant-life is the power to manufacture
protein from less complex bodies; that of animal-life, the absence of
such power." He finds that in form, in the presence of starch, of
chlorophyl, in power of locomotion, in the presence of circulatory
organs, of the body called nitrogen, in the functions of respiration
and sensation, there are no diagnostic characters. He finds, however,
"fairly constant and well-marked distinctions" in the presence of a
cellulose coat in the plant-cell, in digestion followed by absorption,
and in the power to manufacture protein.
The _morphological_ feature of plants is this cellulose coat; of
animals, its absence; the _physiological_ peculiarity of plants, this
_manufacturing power_; of animals, the want of it. But after all the
discussion he says: "To the question, _Is this an animal or a plant?_
we must often reply, _We do not know_."--_The Microscope._

CAMELLIAS.
Next to the rose, no flower* is more beautiful or more useful than the
camellia. It may readily be so managed that its natural season of
blooming shall be from October to March, thus coming in at a time when
roses can hardly be had without forcing. In every quality, with the
single exception of scent, the camellia may be pronounced the equal of
the rose. It can be used in all combinations or for all purposes for
which roses can be employed. In form and color it is probably more
perfect, and fully as brilliant. It is equally or more durable, either
on the plant or as a cut flower. It is a little dearer to buy, and
perhaps slightly more difficult to cultivate; but like most plants the
camellia has crucial periods in its life, when it needs special
treatment. That given, it may be grown with the utmost ease; that
withheld, its culture becomes precarious, or a failure. The camellia
is so hardy that it will live in the open air in many parts of Great
Britain, and herein lies a danger to many cultivators. Because it is
quite or almost hardy, they keep it almost cool. This is all very well
if the cool treatment be not carried to extremes, and persisted in all
the year round. Camellias in a dormant state will live and thrive in
any temperature above the freezing point, and will take little or no
hurt if subjected to from 3 deg.-4 deg. below it, or a temperature of 27 deg.
