On Friday, November I2, the second lecture of the Course was given by Mr. Paul F. Bauder, of Cleveland, Ohio. Mr. Bauder is identified with the National Electric Lamp Association and well qualified to speak on the subject matter of his lecture, " T h e Quality of Light." The lecture was profusely illustrated by colored lantern slides and other pictures descriptive of his subject.

Mr. Jennings has taken part in the Popular Science Courses for many years and is known to all the members of the Institute. It is the earnest desire of the Committee on Instruction that the members and friends of the Franklin Institute will use their endeavors to give these lectures a large attendance. The subjects are all attracting much attention lust at present throughout the entire country and the qualifications and standing of the speakers should insure well-filled houses. Members of the Franklin Institute should avail themselves of the privilege of their membership-cards and attend these lectures. They will all be illustrated with lantern slides, and Witherspoon Hall, in which they will be given, is most attractive and comfortable. Tickets can be had by applying at the Institute.
