The President delivered the anniversary address, taking as his subject the molecular theory of matter.

During the course of his address he showed how by the aid of this theory certain properties of matter, some of them widely known, others not so widely, may be explained, and how certain facts which seem at first sight to be opposed to the theory appear on closer study to support it. He explained the reason why the molecular theory has obtained such a strong hold on the imagination of scientific workers, and in what sense and subject to what reservations it may be regarded as substantially true.

The address was fully illustrated with experiments.
