In connection with the celebration of last Monday night, there was one instance of puerility which we cannot pass over in silence. We allude to the insult offered one of the most respected officials of the college by a crowd of men who collected underneath his window and amused themselves by throwing firecrackers and torpedoes against the panes. Such childishness is not to be tolerated at Harvard; and childishness is a mild term for such ungentlemanly conduct. We are glad to say that student opinion condemns all nonsense of this kind, and we trust that in future celebrations, no amount of excitement will make Harvard students forget the respect due to instructors and their own positions as gentlemen.
