" There is, however, this fundamental difference between plants
and animals ; that while plants can manufacture fresh protoplasm
out of mineral elements, animals, on the other hand, are obliged
to procure it ready made, and in the long run depend upon plants.
■ With this qualification it may be truly said that the acts of all
living things are fundamentally one.'
'• But this unity is not limited to action ; Mr. Huxley maintains
that it extends also to form: —
" ' If a drop of blood be drawn by pricking one's finger, and
viewed with proper precautions and under a sufficiently high
microscopic power, there will be seen, among the innumerable
multitude of little, circular, discoidal bodies, or corpuscles, which
float in it and give it its color, a comparatively small number of
colorless corpuscles, of somewhat larger size and very irregular
shape. If the drop of blood be kept at the temperature of the
body, these colorless corpuscles will be seen to exhibit a marvel¬
lous activity, changing their forms with great rapidity, drawing in
and thrusting out prolongations of their substance, and creeping
about as if they were independent organisms.
" ' The substance, which is thus active, is a mass of protoplasm,
and its activity differs in detail, rather than in principle, from that
of the protoplasm of the nettle. Under sundry circumstances the
corpuscle dies and becomes distended into a round mass, in the
midst of which is seen a smaller spherical body, which existed,
but was more or less hidden, in the living corpuscle, and is called
its nucleus. Corpuscles of essentially similar structure are to be
found in the skin, in the lining of the mouth, and scattered through
the whole framework of the body. Nay, more ; in the earliest
condition of the human organism, in that state in which it has
just become distinguishable from the egg in which it arises.
it has nothing but an aggregation of such corpuscles, and

" ' Thus a nucleated mass of protoplasm "turns out to be what
may be termed the structural unit of the human body. As a mat¬
ter of fact, the body, in its earliest state, is a mere multiple of
