The Creator doubtless gave man a brain with the intention that it should be used. No one, therefore, need fear injuring it by using it to its utmost capacity, for it gains in power by use. The blacksmith's arm does not palsy, and examples are numerous to show that the most intense brain work, when accompanied with temperate habits, is conducive to health and longevity, rather than otherwise. The following from the Scientific American we commend to the thoughtful perusal of all, especially the young:— "Another fact which tells against the theory that 'high pressure' living tends to unhinge the mind may be found in the source of the larger portion of the inmates of insane asylums. The records of asylums show that most of the insane come, not from the busy professional, mercantile, and manufacturing classes, but from those whose lives are a monotonous round of petty drudgery, or, what is equally killing, petty inaction, unfruitful idleness, and dissipation. Frivolity probably leads more men and women to the insane asylum than the hardest and intensest pursuit of mental or material wealth."
