Members of the Harvard Observatory staff are to give a series of talks, stressing the chemical aspects of the universe, to be broadcast over the Yankee Network, represented by the Boston station of WAAB, every week, the first on next Thursday, and the following on Fridays for the succeeding ten weeks at 7.30 o'clock in the evening.

Sponsored by Chemical Society

These short lectures are given under the auspices of the North-Eastern Division of the American Chemical Society, and the members of the University who are to take part in this series were informed definitely concerning the talks only recently. Last night Dr. D. H. Menzel gave an introductory explanation of the talks follow, explaining in general terms, the methods to be used by the scientists in approaching the different phases of the subject, and defining the type of objects to be dealt with.

First Talk on Atoms

The first talk, on Thursday evening, will deal with Atoms, and is to be given by Dr. C. H. Payne. The following week, on Friday, January 20, a discussion entitled "Exploring the Sun" will be delivered by Dr. Menzel. Continuing on Friday nights, the subjects and talkers are as follows: "Touring the Planets," Leon Campbell, instructor in Astronomy; "The What and Why of Schooling Stars," Dr. P. M. Millman: "In Quest of Comets," Dr. F. L. Whipple: "Unravelling Stellar Secrets". Dr. A. J. Cannon: "The Insides of Stars". Dr. Payne: "The Worlds of Gas," Dr. R. J. Hok. Wilson Teaching Fellow: "The Chemistry of Interstellar Space." V. B. Andrews '2b instructor in Astronomy: and "The Chemistry of Evolution." Harlew Shapley. Patne Professor of Practical Astronomy and Director of the College Observatory. The last time that such a series of talks was given over the air was in 1927 when the College took open itself the responsibility to carry out a program without the sponsorship of an outside society. The lectures were of a considerably were general nature, having no specific relation forwards chemical aspects.
