"Mens sana in corpore sano"--or, as the translators will have it. "A sound mind in a sound body"--is a much-slighted adage during the mid-year period. It is disagreeable weather; and fourteen hours of tinkering the mind to a state of pseudo-soundness, seems to please us better than thirteen hours on the mind and one on the body, which more closely follows the wisdom of the adage. To fulfill the sound body there is an excellent and informal exercising class, open to all, previous experience unnecessary, in the Gymnasium daily at 5 o'clock. It requires from street clothes to street clothes just an hour, and renders the remaining thirteen far more effective mind-rejuvenators, than fourteen or even fifteen when the physical is disregarded.
