The Chemistry of Paints and Painting #221073

Various additions and corrections have been made in this, the fourth edition. A few of the paragraphs relating to rather recondite subjects have been abridged or even omitted. Indeed, an attempt has been made, in carrying out the present revision, to simplify, so far as possible, the way in which the results, obtained by chemists in the study of painters' materials, are presented to the artist and the student of art.
