This is an outline of the common practices in the drycleaning and redyeing industry. I t was prepared for use in short courses for persons in the drycleaning industry, given in four cities in Kansas, through the c&peration of the Kansas State Board for Vocational Education. The outline has sections devoted to histow and mowth of drycleaning; education in drycleaning; factors affecting successful drycleaning; cleaning of special types of articles-such as, fabrics, leather, garments, furs, kid gloves, felt hats, and weighted silks; treatment of the various stains; redyeing of fabrics; cleaning solvents and their control; and drycleaning equipment. The outline would be valuable as a reference book in home economics and textile chemistry courses, or as a text for other short courses in drycleaning for members of the industry.

While this book is a valuable standard text, the same plates have been used as those of the 1930 edition with the exception that new pages have been inserted t o give modern recipes on chromium plating, paints, lacquers, stains, and a classified "buyer's guide has been placed in the front of the book for handy reference." A glossary of chemical terms has been added. The editor "has endeavored t o meet the practical requirements of the home and workshop." No clean-cut revision has been made. There is no real increase in value over the 1930 edition. The same need of a chemist and pharmadst as collaborating editors is evident as in the preceding edition. The same absence of American authorities is noticeable. We are informed that the mnfectionery colors made by the A.G.F.A.
"are absolutely nontoxic and can be used . . . . . with perfect confidence in their innocuity." No American makers of food colors are mentioned. Wbile this b w k should be in the library of chemistry teachers, i t has no particular value from the standpoint of chemical education. I t is a time saver for teachers who are asked for recipes by those who still think them magicians, pharmacists, and metallurgists as well as chemists. R. E.
