The following analysis is by Gueter-bock, from the pus of an abscess in the human breast:— Water ......... Fat, soluble only in boiling alcohol . . . Fat and osmazome, soluble in cold alcohol . . . Albumen, pyine, pus globules and granules, soluble neither in hot nor in cold alcohol ....... Loss ......... Lehmann has investigated the chemical composition of the different elementsof pus with great care. Normal pus he found to contain from 14 to 16§ of solidconstituents, of which from 5-6§ belonged to mineral or inorganic substances. 128 TERMINATIONS OF INFLAMMATION, CHAP. a Natural appearance of pus cor-puscles. 6. Appearance after theapplication of acetic acid. The most usual insoluble salts of pus are the phosphates of lime and magnesia,with sulphate of lime; the principal part of the soluble salts is furnished bychloride of sodium. The quantity of fat was found to vary from 2-6§ ; thequantity of albumen in the serum from to §. Casein and the coloringmatter of the blood do not occur in normal pus. A substance which usuallyenters into the composition of pus is pyine. Gueterbock, who discovered it,considers it as a peculiar animal principle. Its exact nature is not is supposed by some to be an *oxide of protein, by others a form of can be precipitated from pus by acetic acid, or by alum. It is soluble in water,but insoluble in alcohol. Pus occasionally contains a peculiar substance, denominated pyocyanine ; it imparts a bluish or greenish hue to the
