As ordinarilv gathered for commerce. The resin is soft, sticky, and opaque, has a slightly yellow color, and a very agreeable Odor. It has a spicy, somewhat bitter taste. If left exposed to the air for some time, it gradually hardens throughout and finally becomes brittle. The resin dissolves readilr and completely in ether, chloroform, and benzene, except for the separation of a small amount of water which it contains and also a very small amount of a white, granular substance. In acetic ester, acetone, ligroin. Methyl and ethyl alcohol it does not dissolve completely unless sufficient solvent is used. With these solvents a white, crystalline residue remains which, with the use of alcohol in limited quantity, amounts to about 25 per cent of the total. This insoluble, crystalline portion of clcmi resin has been the subject of considerable study and will be referred to again briefly in this paper. Very soft Manila elemi contains a considerable amount of water, less than 5 per cent however, while that which has collected on the tree for a length Of time contains very little.
