However disferent from each other the ganglia seem in lhape and size, in
disferent parts, and although, in the progress of the great sympathetic
nerve, the number, and, of cburse, the size of each, varies in disferent per-
sons, I have found, after accurately examining the principal ganglia in man
and in the ox, and particularly the lenticular ganglion of the eye, the gan-
glion in the trunk of the sifth pair*, the cervical, thoracic, and semilunar
ganglia of the great sympathetic, the ganglion in the posterior sasciculus os
the spinal nerves, that they all agree in their general slrucfure, which I
ihall next describe, as it appears to the naked eye, or when viewed with a
common magnifying glass.
In invesligating this subjecl:, I was enabled to trace the nerves in the
ganglia, by attending to their folds or joints, when it would have been im-
possible, from any other circumstance in their stru&ure, to have distinguish-
ed them.
I have already observed, that the nerves os an ox, or other large animal,
are larger than the nerves os a man, although his brain be smaller. The
size os the ganglia bears a proportion to that os the nerves.
In the next place, although the size os the ultimate sibrils os wliich the
nerves are composed, is, perhaps, not larger in the ox than in man; and al-
though, os course, the number os ultimate sibrils is in proportion to the
bulk os the nerves; yet the suniculi, or cords into which these are collected,
are larger in the ox. .Hence I sound, that I could trace the nerves sarther
and more dislinctly in the ox than in man, and more easily and certainly
discover the texture os the ganglia.
