structions in the "Introduction" are ercellent except that "carron-oil" far bums is no longer on the favored list of first-aid treatment. The absence of apparatus supports in the diagrams may leave too much to the ingenuity of the student. The title "Effect of Shape on the Solubility of a Solid" is misleading. Hydrated sodium acetate is probably a more interesting substance for the study of "super-saturation" than is sodium thiosulfate. The familiarizing of a first-course student with a hydrometer is commendable. Some of the analytical determinations are worthy of an excellent first-course mani~ulator. The manual affords a wide latitude in the choice of experiment and is a veritably excellent accompaniment for the text. I n condusion, the reviewer recommends the volume for the use of students who have not had any previous training in chemistry. JESSE E. D AY I s s Oaro S m r s UNIveasrr~ COLUMBUS. Onro

Professor A. F. Holleman Honored. Professor A. P. Holleman, the eminent Dutch organic chemist, attained his seventieth birthday on August 28th, and a special volume of the Recueil des Traoaux Chimigues des Pays-Bas has been dedicated to him in honor of the event. The volume contains numerous papers, from Dutch, British, American, German, French, and Italian authors. Much of Professor Holleman's published work deals with the directive effect of substituents in the benzene nucleus on new substituents entering therein. He is also widely known for his Text-Book of Organic Chemistry, which has been used by many generations of students. Originally written in Dutch, it has run into six English editions, and has also been translated into German, Italian, French, Russian, Polish, Spanish, and Czechoslovak.-Chem. Age
