The progress of knowledge is very irregular, somewhat resembling the movements of an army, of which some battalions are in vigorous health, while oth… - Robert Chambers

In most instances, affectionate relatives and kind friends would wish to prolong the existence of the individual who has reached that age; but if we look at the happiness of mankind in general, we shall find reason to believe that, like all the other general principles of nature, this one carries the impress of an all-wise and beneficent Creator; and that if man had it in his power to alter the arrangement, it may be questioned if he could improve it. At this age the great desires of life are generally accomplished, and the tired laborer in the hardest fields of exertion, which are those of the intellect, has had some years of quiet meditation on the long battle of life to which his days of energy and hope were devoted. The world has, in general, little more use for him; and should he—however meritorious his services, however honored his gray hairs—too long remain an actual living man, seeming to fill a part of the arena in which younger and abler combatants are looking for places, the consciousness of being honored and beloved may give way before the suspicion that he has become an encumbrance to the circle he once adorned.

The working-classes require leaders and wise heads from their own body—patriarchs, in the old acceptation of the term—to keep them right in moments of excitement. The causes of early death prevent the existence of such a class of men, sobered and wise from experience, in sufficient numbers to discipline the youthful and fiery spirits who, confident in their ignorance, plunge themselves and those depending on their exertions into ruin.

Geometry is that of mathematical science which is devoted to consideration of form and size, and may be said to be the best and surest guide to study of all sciences in which ideas of dimension or space are involved. Almost all the knowledge required by navigators, architects, surveyors, engineers, and opticians, in their respective occupations, is deduced from geometry and branches of mathematics. All works of art constructed according to the rules which geometry involves; and we find the same laws observed in the works of nature. The study of mathematics, generally, is also of great importance in cultivating habits of exact reasoning; and in this respect it forms a useful auxiliary to logic.
