The lecture in Sanders Theatre, this evening, has certainly the merit of oddity. While being strictly neither a lecture nor a concert, it combines the two elements in a way that should make it not only instructive, but very entertaining. The concert part of the program, moreover, is of a type which has probably never before been heard in Sanders Theatre. The old instruments which Mr. Steinert has, with a great deal of care brought together, form in themselves, a collection of no little interest, while an explanation of their use with actual examples added will give to the performance this evening, the character of an exceptional opportunity.
