So much has been said at more or less regular intervals concerning the ventilation of some of the older college lecture-rooms, that we are reluctant to rake up the subject. But occasionally, after one's brain has been dulled by the suffocating air of a close room or racked with fears of pneumonia and bronchitis, it is impossible to keep down a feeling of mingled indignation and despair. We know that it is no easy matter for the University authorities to remedy the evil; that improvements cost money; that the University is cramped for funds which may be applied to such purposes; and finally, that the best of ventilating appliances is apt to prove unsatisfactory. Nevertheless, on the principle that the one who never murmers when he is dissatisfied is not likely to have his condition bettered, we make this protest.
