liquids and is far less soluble in any solvent than linseed oil. We have had specimens of it for months in dilute acid and weak alkaline solutions; also in spirits of turpentine, petroleum, naphtha, linseed oil, alcohol, chloroform, acetone, carbon-bisulphide, and water, and in most of these liquids we find but slight decomposition or solution of it. These experiments indicate its power of resistance to atmospheric influences.

A layer of dried linseed oil (linoxyn) is not waterproof, although no compound is probably chemically more resistant to atmospheric influences (not mechanical wear). For example, it is claimed that a gallon of oil spread upon one hundred square feet of surface will outwear a gallon of any paint spread upon the same area of a similar surface ; but it maybe noted that it will require about  three  times  as  many coatings of  the
