This evening at 7.30 p.m. in Sanders Theatre, Rev. Dr. Henry Lunn is to address the religious societies on "Christian Reunion." He is a young man of only forty years but a great worker. In London every Sunday about 1250 poor boys gather to listen to him as chaplain of the Polytechnic School. Apart from other work, however, he is president of the "Grindewald Conferences," which last summer numbered 2500 of the most prominent religious leaders of all denominations from Europe and America. He will show in his address the need of this union and the essential points on which all Christians agree. It can not but be of interest to Harvard men, especially as it comes from one who has a very complete knowledge of the subject.
