Few, I think, will attempt to deny that it is desirable that all medical students should attend a course of lectures on the important subject of Mental Disease. And further, that these lectures should be compulsory, no matter what the university or medical school may be at which the students matriculate, or where they may intend to take their degrees or diplomas. Some there are who may object to these lectures being compulsory, for the reason that this course of lectures would be the addition of another subject to the already lengthened curriculum of medical studies. I think we are all agreed that the medical student of the present day has enough, and more than enough, of subjects to occupy the short term of four years that is usually allotted to his studies.
