One of our well-known professors in philosophy has been in the habit for some time past, of having the men of his courses come to his house separately, after an examination, and read their blue-books to him. Although this is done to save the professor's eyes, at the same time the practice combines many very material advantages. For although almost every one is dissatisfied with the result accomplished on an examination paper, or with the mark returned, there is usually no method of finding out in what one was right or wrong. This is especially true of those more indefinite subjects in which mental reasoning, and not the mere effort of memory, enters largely into the consideration of work done. But when a man reads his book over to his professor, he seizes that opportunity of personal intercourse by which he may gain a definite idea of how well or how badly he has done in the examination. Many a man does not clearly know what he has right, especially when original reasoning is required of him. But probably no man who responds to this professor's request will leave his presence without having realized thoroughly what his work was worth in all its particulars. This knowledge may not be consoling alike to all, but it is an advantage that we wish could be more extended.
