A Survey of American Biological Chemical Literature.

ABOUT a year ago Sparks and NoyeS2 prepared a census of the periodical literature of chemistry published in the United States. They selected for their study tile five American chemical journals: American Chemical Journal Journal of the A merican Chemical Society Journal of Biological Chemistry Journal of Industrial and Engineering Chemistryj Journal of Physical Chemistry This study showed that during the five-year period, 1909-1910 to 1914-1915, the Journal of Biological Chemistry gained 150 per cent. in the nlumber of published pa(ges; the Journal of Industrial and Engineering Chemistry, 78 per cent.; the Journal of the American Chemical Society, 88 per cent.; while the Journal of Physical Chemistry showed a loss in published pages of only 2 per cent. (The American Chemical Journal was merged with the Journal of the American Chemical Society in 1914). With this study as a model and an incentive, the writer has made a somewhat similar investigation of the biological-chemical literature during the period 1907-1916. The question as to what properly belongs under the heading biological chemistry is probably open to discussion. It seems fair, however, to accept the decision of tlhe men who are in charge of the various sections of the Biological Chemical division of Chemical Abstriacts. All papers which are found in
