The next step in the investigation is (1) to separate and distinguish the constituents present in each group from each other; in the Proteids, the various albumins; in the Fats, the saponifiable fats, cholesterin, etc.; and in the Extractives, the urea, uric acid, etc., and the composition of the Soluble and In- soluble salts; (2) to determine the nature, special characteristics, and ultimate chemical composition of each substance so separated. 3. Composition and constitution of or- ganic substances—There is no essential difference between organic and inorganic chemistry. Organic chemistry is simply the chemistry of carbon compounds, and accordingly we find that the organic principles we meet with in the animal body consist of carbon united in various proportions with hydrogen, oxygen, nitro- gen, and some less abundant elements, such as sulphur phosphorus, and iron. 4. Nitrogenous and non - nitrogenous compounds—The carbon compounds, or organic principles, for purpose of convenience are divided into two distinct groups, viz. : (1) The non-nitrogen- ous, and (2) the nitrogenous; those in which the element nitrogen is absent, and those in which it is present Both these groups are represented by the principles which form the basis of the animal tissues and fluids, the first by the starchy, saccharine, and o eagmous principles, the second by the proteid or albuminous These principles, which are usually dis- tinguished by the term proximate, after fulfilling their purpose m the economy, undergo a series of changes (metabohc), are broken up and oxydised, and are Jna ly red d . the £omer tQ ^7 ^ ^ ^ « the latter to carbonic acid, water, and ammonium car- bonate (urea).
