Information on Colloid Chemistry Editor of Industrial and Engineering Chemistry: About a year ago [THISJOURNAL, 15, 321 (1923)J I asked for assistance in preparation of a comprehensive book on “Colloid Chemistry, Theoretical and Applied,” and I am glad to say t h a t over one hundred and fifty of the best men of all countries have promised contributions to it, thus insuring its international character. Papers have already been received from the following: CANADA F. E. Lloyd W.H. Martin CZECHOSLOVAKIA G. Georgeivics

An enormous range of topics is being covered, including technology, agriculture, biology, and medicine. Thus there are papers on cancer, tuberculosis, concretions (gallstones, calculi, etc.). If any of the readers of THISJOURNAL can send me reprints of papers germane to the book, or suggestions as to points that they would like to have included or discussed, I shall appreciate i t and make the best use I can of the information. I am looking for all the cooperation I can get to make this book a compendium of our present knowledge of colloid chemistry, so that it may be of the widest possible use, not only to chemists, but also to manufacturers, biologists, physicians, and many others.

Register Your Protest Editor o j Industrial and Engineering Chemistry: A bill, S. 845, “To authorize the Department of Commerce, by the National Bureau of Standards, to examine and test manufactured articles or products for the owner or manufacturer thereof, t o issue a certificate as to the nature and quality of such manufactured articles or products, and t o prevent the ilIegal use of such certificate,” introduced by Senator Fletcher and referred to the Committee on Commerce, has just been called to our attention. We have read this bill carefully and discussed it a t our semiweekly conference. We cannot see t h a t the provisions of the proposed law will serve any useful governmental purpose, nor do we believe t h a t the services to be provided are a proper governmental function. It is not designed to assist in conserving the health of the nation or to protect its coinage and precious metals. It looks to be rather an attempt to increase greatly the force of the Bureau of Standards with no corresponding benefit to the public a t large. Furthermore it seems t o trespass greatly upon the field of activity of the many thousand chemists who are employed by the better type of manufacturer or who are maintaining commercial laboratories throughout the country. I t is our belief t h a t it is time to call a halt in t h e aggressive and almost universal tendency toward unnecessary and irksome paternalism on the part of many of our legislators. We hope that our fellow chemists will see the merits of our position and that they will be cognizant of what is impending and take such action as they properly may to prevent Senate Rill 845 from becoming a law.
