The best investment a parent can make of his wealth is in the proper education of his children. Life is not merely to be born, to grow, to eat, to drink, and breathe. Noise is not music. Life is such as we take it and make it, or rather as it is taken hold of and made for us by those to whom the care of our youthful days is intrusted. Let us endeavor to picture to ourselves the being likely to be produced by a system of teaching and training, continued for successive generations, such as we have indicated above. Let us imagine the full development of the most complex of nature's organisms--a part of the one living organism of the Universe, the latest product of her laboratory; considered, as a part of the great Cosmos, the most perfect, yet but an integer in the whole; the ultimate development of nature's chemistry, yet forming an atom of her living unity; combining and possessing the widest relationships, even embracing therein the entire volume of that nature whose true relationships comprise all knowledge, truly "the noblest study of mankind." Let us try and draw the picture of the developed man! Robust and supple of limb, symmetrical of shape, his muscles swelling beneath their healthy development; with head erect, conscious of his strength and skill, which he puts forth for the protection of the weak, and for the purpose of drawing from nature her bounteous stores; free from sickness or disease, in harmony with nature, at peace with his fellow-men, possessing a competent knowledge of nature's laws, and guiding his conduct to be in accord therewith, "sitting beneath his own vine and fig-tree," "blessed in all the works of his hands," and diffusing blessings and happiness around. Such is the picture of THE HEALTHY MIND IN A HEALTHY FRAME, which it is in man's power to procreate and rear! _APPENDIX._ DEPARTMENT OF PUBLIC INSTRUCTION,} CORNER OF GRAND AND ELM STREETS, } NEW YORK, June 5th, 1869. } TO MAGNUS GROSS, Esq., _Chairman of the "Executive Committee for the Care, Government and Management of the College of the City of New York:"_ DEAR SIR,--I have observed with surprise, and with a sense of deep regret, that the proposition is entertained by a large number of the Trustees of filling the chair of Latin and Greek, now vacant, and even of establishing separate chairs for each, at the College of the City of New York; involving, with the necessary tutors, an outlay of not less than $20,000 per annum. The subject in all its bearings is one of too vast importance to be treated in the ordinary method of discussion by the Committee, and I therefore beg leave to place my views in writing, to insure their receiving more matured consideration than oral observations could secure.
