Ήοτοαάαψ analytical chetmstry is no less important than in 1903, but the other branches havegroion açtmsively. Η.Ά. Laitinen ciate editor of the/. Am. Chem. Soc, I objected to the fact that the Table of Contents did not list analytical chemistry as a subdivision. This became a painful issue settled, not by adding analytical to one of the sections, but by doing away with two sections altogether. American journals publishing analytical papers. Although Germany since 1862 had its Z. Anal. Chem. published by Fresenius, and the United Kingdom since 1874 The Analyst (published by the Society of Analytical Chemists), it took a long

time in this country before the analytical chemists had their own journal. Going over the Table of Contents of the/. Am. Chem. Soc. between 1900 and 1910,1 was impressed with the huge number of ana­ lytical papers of a typical classical charac­ ter published in this (prestigious) journal. Many analytical papers are also found in the American Chemical Journal, Technol­ ogy, and Industrial and Engineering Chem­ istry. In 1929 the first volume of Industrial and Engineering Chemistry, Analytical Edition was published. Several of us (par-

ticularly Foulk, Willard, Furman, Popoff, Mellon, Meloche, and Swift) objected to the fact that the title did not do justice to the role of analytical chemistry as a scien­ tific discipline. It was not until 1948 that the first volume of our present journal Analytical Chemistry was published as Volume 20. Further details on this journal are found in the history of our Analytical Division of the ACS. From the above it is quite evident that early this century analytical chemistry already flourished in this country. As H. A. Laitinen (private comment) stated: "It is evident that a large part of American chemistry in 1903 was analytical. Nowa­ days analytical chemistry is no less impor­ tant than in 1903, but the other branches have grown extensively." References (1) W.
