NERVOUS SYSTEM,
Suppose, then, both animals to be sed on milk, we must believe that the
milk paries two hundred times quicker through every medullary sibre os
the brain os the ox than through the medullary sibre of the brain os the
man.
2. In monfters, I have sound the limbs very plump, though the brain
was very small *. Nay, in some monfters, the head has been wanting, yet
the limbs were as large and persect as common. In other monsters with
one head and two bodies, I have sound that the brain surnished the nerves
os the head and spinal marrow on the right side os the monster; yet the
lest spinal marrow, at the top os which there was only a small medullary
knob, about the size os a large pea, was as perfect, as the right one, and
that body and its limbs were as large and well nourished as those on the
right side s. On the other hand, where there were two heads os the or-
dinary size, and only one body, the limbs were not remarkable sor their
size $.
3. We see that organs, os which the nerves are fo fmall that we cannot
trace them bv difle&ion, as the bones, the placenta, &c. grow as quickly
as the other organs in which the nerves are large and numerous^
4. A year aster I had cut acs oss the sciatic nerve of a living srog, I could
not perceive that limb smaller than the other, yet it continued to be insen-
sible and motionless. Nay, when I had broken the bones os the insensible
limb, or wounded the fkin and sseih, I sound that the callus sormed, and
the wounds healed as readily as is the nerve had been entire. The event
was the fame, after dividing, transverfely, the lower or pofterior end of
the spinal marrow of the frog.
