In some of these, as in the Cod and Haddock, a red membrane, consisting of a great number of leaves or duplicatures, is found within the air-bag, which probably secretes this air from the blood of the animal. The air at the broad end of the egg is probably an organ serving the purpose of respiration to the young chick, some of whose vessels are spread upon it like a placenta, or permeate it.
Next to the stomach comes the longest section of the alimentary canal, the middle gut or small intestine. It is a short, horseshoe-shaped loop of the gut. The largest glands of the alimentary canal open into it the liver, the chief digestive gland, that secretes the gall, and the pancreas, which secretes the pancreatic juice.
One of the most extraordinary characteristics of the beaver is, that it secretes from certain glands a peculiar odoriferous substance called "castoreum," or "bark-stone" by the trappers. So strangely are the beavers attracted by this substance, that sniffing it up with their nostrils, they will hurry towards it to enjoy the scent. It is consequently the bait used by trappers.

The lachrymal gland which secretes the tears keeps the above parts moist. The eye is the essential organ of vision. It is formed by a spherical shell which encloses fluid or semisolid parts. The shell is anteriorly made up of a transparent convex membrane, the cornea, while the remainder of its wall is formed by three opaque layers or tunics. The external tunic is the sclerotic.
All this could be freely admitted. But then the question arose, Is mind the originating source of the movements of matter, or is it not rather itself the product of them? There were those who did not shrink from affirming that matter produces thought, even as the liver secretes bile. Others preferred to take what seemed to be an intermediate course.
They have a gland under the tail, which secretes a liquid of most disagreeable odour, and causes them to pass into a sort of proverb. They feed chiefly on roots, nuts, and other fruits; attack the nests of wasps, or wild bees, and devour their larvæ, themselves, or their honey, with a perfect indifference to their stings, which cannot pierce through their tough hide.
Who could ever see it? Thus by degrees it passed into a Doubt, a Relation, some faint Possibility; and at last into a highly-probable Nonentity. Following Locke's footsteps, the French had discovered that 'as the stomach secretes Chyle, so does the brain secrete Thought. And what then was Religion, what was Poetry, what was all high and heroic feeling?
Wait a little, and thou shalt have his head." "We should have few heads or prisoners either, if thou hadst the care of them," said Francois sharply. "I say that the prisoner secretes something, and that I will see it. Show your hands, dog of an aristocrat!" Monsieur the Viscount set his teeth to keep himself from speaking, and held out his hands in silence, toad and all.
The cavity of the trunk immediately above the diaphragm. A fabric, or texture, composed of cells and cell-products of one kind; as, for example, nervous tissue, muscular tissue, fatty tissue. Se cre'tion. A substance made from the blood, the special character of which depends upon the kind of gland that makes, or secretes, it.
