Harvard Natural History Society.

This evening at 8 o'clock in Sanders Theatre Paul Du Chaillu will lecture on "The Gorilla and other Apes of the Great Equatorial Forest." Mr. Du Chaillu accepted the invitation to speak to members of the University, although he does not usually deliver public lectures on invitation.

The Natural History Society has made it possible for all members of the University to hear the lecture. Admission will be by ticket only, but any student may obtain two tickets by applying at Thurston's.
