When the Professor landed at Liverpool, he would, on no account, suffer the carpet-bag, containing his calculations, to be taken out of his sight. Several inquisitive persons, however, made the best use of their own eyes, to ascertain the name of the extraordinary observer, and found it to be legibly inscribed with the well-known name of Scoresby. That his investigations may be the more readily impressed on the reader's mind, we conclude with a summary of them. It would seem from Dr. Scoresby's intrepid investigations, that the highest waves of the Atlantic average in Altitude 43 feet Mean Distance between each Wave 559 " Width from Crest to Crest 600 " Interval of Time between each wave 16 seconds Velocity of each Wave per hour 32-1/2 miles. HOW TO KILL CLEVER CHILDREN.[24] At any time in life, excessive and continued mental exertion is hurtful; but in infancy and early youth, when the structure of the brain is still immature and delicate, permanent injury is more easily produced by injudicious treatment than at any subsequent period. In this respect, the analogy is complete between the brain and the other parts of the body, as is exemplified in the injurious effects of premature exercise of the bones and muscles. Scrofulous and rickety children are the most usual sufferers in this way. They are generally remarkable for large heads, great precocity of understanding, and small, delicate bodies. But in such instances, the great size of the brain, and the acuteness of the mind, are the results of morbid growth, and even with the best management, the child passes the first years of its life constantly on the brink of active disease. Instead, however, of trying to repress its mental activity, as they should, the fond parents, misled by the promise of genius, too often excite it still further by unceasing cultivation and the never-failing stimulus of praise; and finding its progress, for a time, equal to their warmest wishes, they look forward with ecstasy to the day when its talents will break forth and shed a lustre on their name. But in exact proportion as the picture becomes brighter to their fancy, the probability of its becoming realized becomes less; for the brain, worn out by premature exertion, either becomes diseased or loses its tone, leaving the mental powers feeble and depressed for the remainder of life. The expected prodigy is thus, in the end, easily outstripped in the social race by many whose dull outset promised him an easy victory.
