It was particularly gratifying to see the large audience which assembled last evening to listen to Mr. John C. Ropes' lecture on the Virginia Campaign. Mr. Ropes it will be remembered, lectured two years ago before the Historical Society, on the First Napoleon, and has at other times and in other ways very materially aided the society in the endeavors to make itself useful. We understand, also, that Mr. Ropes was influential in getting up the present course of lectures which has proved so successful and which has given the society a firmer foothold as a college society than it ever before enjoyed. To Mr. Hart, the president of the society, much praise is also due for his successful efforts in establishing such an interesting course of lectures and in arousing such a healthy interest in the history of our own country.
