The deep interest felt by the undergraduates here in the lecture which M. Coquelin will give in Sanders Theatre tomorrow, was shown by the immediate disposal of all the best seats, and in a short time nothing but admission tickets could be procured. The position in which M. Coquefin will be placed of lecturing before such a large body of American students will be a novel one, the more so because this opportunity will probably be the only one he can find time to accept during his tour in this country. That he may never regret his experience in talking to us, the welcome accorded him should be warm and sympathetic. That M Coquelin has won the sincerest thanks of all the members of the university, goes without saying, and he may always look back to his reception in Cambridge as one of the pleasantest features of his Boston engagement.
