Open Night Lecture

The second in the series of Open Nights at the Harvard College Observatory which are being held under the auspices of the Bond Astronomical Club will be held this evening at 7.30 o'clock. The speaker will be Professor E. S. King, who will speak on the subject "Measuring Starlight."

The Open Nights consist of a short non-technical talk, followed, weather permitting, by telescopic observations of the heavens. Members of the club will also explain exhibits showing the work of the observatory.
