The idea of duty, that recognition of something to be lived for beyond the mere satisfaction of self, is to the moral life what the addition of a great central ganglion is to animal life.

This organ consists of a vast number of distinct ganglia, or separate masses of nerve matter, each capable of performing separate functions, but united through the cerebral action into a harmonious whole.

The former appears to be connected with the restraining ganglia; the latter with the exciting ganglia.

The heart would quickly become exhausted if the exciting ganglia had it all their own way, while it would stand still if the restraining ganglia had full sway.

A double chain of nervous ganglia, situated chiefly in front of, and on each side of, the spinal column.

Since 1910 with the aid of Dr. Minot, I have succeeded in preserving alive the nerve cells of the spinal ganglia of adult dogs and rabbits by placing them in defibrinated blood of the same animal, through which there bubbled a current of oxygen.

There is pressure upon the submaxillary and subclavicular ganglia, and probably the axillary ganglia also.

The gray fibers occur chiefly in branches from the sympathetic ganglia, though found to some extent in the nerves of the cerebro-spinal system.
