The one society which is, perhaps, unique with Harvard, is the Photographical Society. The society is one of the most successful which the college contains, and has shown itself to be thoroughly active and progressive, But, notwithstanding the excellent work which the members of the society have produced, the nature of the organization is such that in the past but little opportunity has been afforded it to interest the public in its work. With the purpose of overcoming this disadvantage it was proposed that the society should give a public exhibition of the most praiseworthy work of its members, and extend to its many friends this opportunity of an examination into the work of Harvard photographers. After some agitation of the matter the society determined to undertake the exhibition, and secured Professor White's recitation room in Sever as an exhibition room. The society is to be congratulated upon the opportunity which is thus afforded it for a successful presentation. There is, perhaps, no room in the Harvard buildings which is so well fitted to heighten the effect of the exhibit. The great taste which has been displayed in the finish of the room will here serve a double purpose. While the exhibit might appear stiff and unartistic without some accessaries as a relief, Professor White's room in its classic statuary and richly colored walls, will prove a most fitting means of a thoroughly artistic display. It is intended that this exhibit shall be thrown open to the public next Wednesday, and we need hardly prophesy, from the enterprise of the management, that the success of the exhibition is assured.
