Dr. Rock’s lectures

Dr. John S. Rock’s lecture last Monday evening, on ‘The Lights and Shadows of Ancient and Modern Tribes of Africa,’ proved so highly interesting, he will soon comply with a general request for its repetition. It is well adapted for a popular Lyceum lecture, and we hope he will receive many invitations during the season.
