to the idea of isomeric compounds and the use of chemical equations were points of unusual interest. Pictures of Dalton's original apparatus were shown. The closing paper was a valuable demonstration of the use of motion pictures, especially with the compact kodoscope, in visual chemical instruction. The taking of such pictures requires little time and the cost is moderate. The possibilities for showing both correct and incorrect manipulation and for illustrating manufacturing processes are unlimited. A brief business meeting was held in which reports from the following committees were presented: Nomenclature, A. P. Sy, Chairman; Research on Problems of HighSchool Chemistry Instruction, Earl R. Glenn,
Chairman. Because of lack of time these reports were referred to the Committee on Chemical Education for consideration and action. Plans for the Philadelphia Meeting were discussed. It was voted to recommend that three groups of papers be called for, based upon the following central thoughts: (1) History of Chemical Education during the past 50 years, with a prophecy concerning the future. This may be a joint offering with the Section of Chemical History. (2) The Status of Chemical Engineering Education, in conjunction with the Division of Industrial and Engineering Chemistry and the Committee of Chemical Engineering Education. (3) Types of Chemical Education employed in other lands, if visiting chemical educators can be secured to speak. Two additional committees were added to our list:
Research on Problems of College Chemistry Instruction. Aids lo Visual Chemical Instruction. B. S. HOPKINS,Secretary
Motor Fuel Made from Water and Coal. How synthetic fuels for internal combustion engines may he made from coal and water was described a t the Tulsa Meeting of the American Chemical Society by C. R. Hoover of Connecticut Wesleyan University, and associate investigators. The material employed in the process is the familiar water gas, made by passing a current of steam over a bed of red hot coal. When this watergas is conducted a t high temperature and pressure over a catalyzer, such as finely divided nickel, copper, iron, or other metal, the carbon in part combines with the hydrogen, giving a gaseous mixture that contains from twenty-five t o thirty per cent of compounds of higher heating value. By increasing the pressure of the process i t is possible to abtain compounds containing oxygen as well as hydrogen and carbon, such as alcohols and aldehydes of various kinds, some of which may prove on further investigation to have commercial possibilities.-Science Senice
