Besides these, there are other substances known to exist, but which being doubtful, or not well determined as imiuediate principles, it is unnecessary here to enumerate. The organic substances or coagulable immediate principles constituting the third class, compose the greatest part of the body, the principles of the first class being in much smaller proportions; whilst those of the second, except the fatty principles, being formed by dis-assimilation or waste, to be quickly thrown off, must be regarded as merely accessory to, and not as original components of the organism. The first and third classes (including fat) then are alone assimilable. Or THE First Class. Oxygen (0) is an immediate principle when it exists in a free state; it is thus dissolved in the blood, and acts as a vital stimulus — its combination with the tissues and elements producing heat. Hydroijen (H) exists free in the stomach and large intestine, though none has as yet been found in the blood. Nitrogen (N) is found dissolved in the blood. Carhonic Acid (Coj) resulting from the combination of oxygen with the carbon of the tissues, etc., is found dissolved in all the fluids. It is removed princi- pally by the lungs. ]Yater (Protoxide of Hydrogen, HO) is one of the most important iuime- diate principles, forming as it does a part of every tissue or fluid in the organ- l<!m ; and is essential to their existence; nearly every tissue is mere than half](https://iiif.wellcomecollection.org/image/b21084452_0036.jp2/full/800%2C/0/default.jpg)
