Several kinds of glands are situated in the walls of the intestines. There are glands which are collected together in patches, which go by the name of their discoverer, and are called Peyer's patches. These are the glands in the small intestines which are inflamed and ulcerated in typhoid fever, and in describing the precautions to be taken in typhoid fever, I shall beg you to bear in mind that those glands are inflamed and ulcerated, and may form holes.

The small intestine then winds about for a considerable time, and at last ends in what we call the large intestine. It does not end in the very extremity of the large intestine, but a little way from the beginning of it, and the piece that remains goes by the name of the coecum, or blind end.

The undigested parts of the food, which cannot be absorbed, pass through the small intestine into the large intestine, into the part called the c‘cum, and just there there is a fold of mucous membrane which acts as a valve, so that the undigested parts of the food cannot get back again. From the c‘cum there starts out a little appendix, something like a worm in shape; this has a little tube running almost up to its end, and connected with the cavity of the intestine. This tube, so far as we know, has no use at all; it corresponds to certain things which are of more or less importance in lower classes of animals, but although we have no idea of its use, if it has any, it may do a very great deal of harm; sometimes things that have not been digested get up into the end of this little tube, and they stay there and set up irritation, causing inflammation, which extends to the peritoneum, the bag which is folded around the organs of the abdomen, and then death almost always ensues. Things that are liable to get into that little appendix ought not to be swallowed; such things are the stones of fruit. A great many people die, without the cause ever being suspected, from cherry-stones getting into it.

The large intestine is continued from the c‘cum, rising upwards on the right side of the lower part of the abdomen, forming what is called the ascending colon. It then runs across below the stomach, and downwards on the left side, and it ends in a straight piece which goes by the name of the rectum. The walls of the large intestine are very much the same as those of the small, only that the muscular fibres running along it are collected in strong bands, so that they pucker it up, and throughout the course of the large intestine very little is done with the food, except that the more indigestible parts of it are passed along in order to be got rid of; though probably a little absorption occurs as well.
