by Messrs. Scott, Greenwood & Co. In my opinion _no_ varnish maker
ought to be without it; moreover, it is the best text-book that

to my students and trade friends."--CHARLES HARRISON, Lecturer on

especially commend itself, as that is the part of the subject which
most readers would buy the book for."--_Chemist and_ _Druggist._
