tion. They will be found the primary factors and
elementary forms of every calculus and of every diagram in the algebra and
geometry of a scientific physiology. Accordingly, we shall recognise the
same forms under other names; but at each return more specific and
intense; and the whole process repeated with ascending gradations of
reality, _exempli gratia_: Time + space = motion; T_m_ + space = line +
breadth = depth; depth + motion = force; L_f_ + B_f_ = D_f_; LD_f_ + BD_f_
= attraction + repulsion = gravitation; and so on, even till they pass
into outward phenomena, and form the intermediate link between productive
powers and fixed products in light, heat, and electricity. If we pass to
the construction of matter, we find it as the product, or _tertium aliud_,
of antagonist powers of repulsion and attraction. Remove these powers, and
the conception of matter vanishes into space--conceive repulsion only, and
you have the same result. For infinite repulsion, uncounteracted and
alone, is tantamount to infinite, dimensionless diffusion, and this again
to infinite weakness; viz., to space. Conceive attraction alone, and as an
infinite contraction, its product amounts to the absolute point, viz., to
time. Conceive the synthesis of both, and you have matter as a fluxional
antecedent, which, in the very act of formation, passes into body by its
gravity, and yet in all bodies it still remains as their mass, which,
being exclusively calculable under the law of gravitation, gives rise, as
we before observed, to the science of statics, most improperly called
celestial mechanics.

In strict consistence with the same philosophy which, instead of
considering the powers of bodies to have been miraculously stuck into a
prepared and pre-existing matter, as pins into a pin-cushion, conceives
the powers as the productive factors, and the body or phenomenon as the
fact, product, or fixture; we revert again to potentiated length in the
power of magnetism; to surface in the power of electricity; and to the
synthesis of both, or potentiated depth, in constructive, that is,
chemical affinity. But while the two factors are as poles to each other,
each factor has likewise its own poles, and thus in the simple cross--

With M M, the magnetic line, running from top to bottom, with _f f_ its
northern pole, or pole of attraction; and _m m_ its south, or pole of
repulsion, and E E, running from left to right, one of the lines that
spring from each p
