bold-faced headings stand out and the 10-point Scotch-Roman solid type is extremely easy on the eyes. (This review is printed in &point type. The main body of the JOURNAL is in 10-point type.) However, one does not usually do extensive reading in a dictionary and it would seem that an 8-point type would have done as well. The frequent indentations and spacings (again kind t o the eyes) lead to a considerable proportion of broken lines and a high percentage of blank space per page, which is huther increased by generous margins. An area of 14.8 X 20 cm. circumscribes all the printed matter on an 18.5 X 26.4-cm. page, including index headings and page number, as well as intercolumnar spacing. Some space could also have been saved by a mare selective use of structural formulas. Any chemist would be mateful for the full presentation of formulaslike those of berberine, bi~ianicacid, and bisabolene, but few need t o have anthracene, benzene, and ochlorobenzaldehyde diagrammed for them.

T o many American chemists this little book should he of special interest. Wohler, one of Berzelius' most famous students, was one of the teachers of Ira Remsen who, in turn, through his position a t The Johns Hopkins University, became the teacher of a generation of the leaders of chemistry in the colleges and industries of this country. I n other words, hundreds of Americans now trace their chemical lineage hack t o Berzelius. The printing is very clear and on good paper. The style is that of the translator and may be characterized as somewhat matter-of-fact. The scholar will find the many explanatory notes of value, as he will the parallel passages from the three manuscripts which constitute the original sources. Two of these.manuscripts are in the handwriting of Berzelius. The third was written by Mme. Berzelius. A list of the most famous pupils of Berzelius is included. AVERYA.
