Dr Anderson—It is a peculiar pleasure to me to be the organ of the Society this evening for presenting to you this token of the approbation of this Society and its Council.

As there must be many now present who are unacquainted with the origin, conditions, and mode of adjudication of the Keith Prize, I hope that others will bear with me for a moment till I state these very briefly. The prize was founded by the late Sir Alexander Keith of Dunottar and Ravelston, to be given to the author of the best paper read in this Society during each successive biennial period. The Council were appointed to administer the fund, and to adjudicate the prize. The adjudication is determined by advice of a committee of the Council specially nominated for the purpose.
