THE success of the lectures given under the auspices of the Natural History Society leads us to hope not only that the course may be continued next year, but that lectures may be delivered on other subjects as well. The attendance at Professor Hedge's lectures on German literature is so large, even at the inconvenient hour of four in the afternoon, that the lecture-room is insufficient for the audience. If the evening readings could now and then be varied by lectures of a literary character, the authors read would be listened to with doubled interest. Most undergraduates are as profoundly ignorant of all that concerns the French, Italian, and Spanish literature as they are of German literature, and, having no acquaintance with the languages, are obliged to remain in ignorance of a great deal that is indispensable for every fairly well-informed man. That a large number of the ladies of Cambridge would lend their presence to swell the number of listeners no one can doubt who takes the trouble to cast his eye over the audience at any one of the lectures now in course of delivery.
