BENT TO DELIVER CHEMISTRY LECTURE AT MALLINCKRODT

H. E. Bent, assistant professor of Chemistry, will deliver the second in a series of five lectures on the progress of the sciences in the last hundred years. The talk which will be illustrated with experiments will be given in Mallinckrodt B-1, Thursday afternoon, July 20, at 4 o'clock.

An attempt will be made to cover the amazing discoveries which have given chemistry such an important industrial function to perform in the last hundred years. Non-technical terms will be used so that a knowledge of the subject is not indispensable for enjoying the lecture.

Chemistry was practically at a stand-still until the time of Priestly, the discoverer of oxygen. Since then isolation of elements and a true understanding of the structure of matter have enabled scientists to make chemistry one of the most powerful benefactors of man. The molecular theory, the periodic laws, and the more recent physical contributions will probably be explained at length.
