FATTY ACIDS AND T H E I R By A. W. RALSTON
DERIVATIVES
This book by an authority on the subject is divided into two sections. Part I describes the various fatty acids, their occurrence in nature, synthesis, and physical properties. Part II is devoted to a study of the synthesis, properties, and uses of the fatty acid derivatives. The preparation, physical and chemical properties, and uses of major derivatives are discussed in detail. 1948 986 Pages $10.00

VAT D Y E S T U F F S AND VAT DYEING By M. R. FOX
323 Pages
Developed at the request of and in cooperation with the A.A.T.C.C. Committee on Fastness to Light the new holders and lower ring prevent discrepancies in test results caused by unequal distances from the specimen to the light source resulting from improper alignment of the holders. This new method of suspension improves accuracy of test results since it materially reduces the possibil ity of deviation of the specimens from the vertical due to the human element or for mechanical reasons. T h e lower ring can be installed on all Model FDA and FDA-R Fade-Ometers now in operation, adap ting them for use with the new type specimen hold ers. In addition to the holders finished in baked-on gray enamel we now are also able to supply at slight additional cost the new modified specimen holders fabricated from a dull finish stainless steel. Write for complete information on this new im proved method of specimen suspension for your old machines.
