When about eleven years of age she suddenly changed her habits of eating, and steadfastly refused, at the table, all kinds of food which partook of flesh and fish. The family were alarmed, and afraid she was ill. When they made inquiry concerning it, she hesitated to assign the reasons for her conduct; but, on being pressed closely, she confessed that she abstained for conscience' sake; that she had become fully convinced, from reading and reflection, that she ought not to eat animal food. It was in vain that the family and neighbors remonstrated with her, and endeavored, in various ways, to induce her to vary from her purpose. She continued to use no fowl, flesh, or fish; and in this habit she continues, as I believe, to this day, a period of some twelve or fifteen years. JOHN WHITCOMB. John Whitcomb, of Swansey, N. H., at the age of one hundred and four was in possession of sound mind and memory, and had a fresh countenance; and so good was his health, that he rose and bathed himself in cold water even in mid-winter. His wounds, moreover, would heal like those of a child. And yet this man, for eighty years, refused to drink any thing but water; and for thirty years, at the close of life, confined himself chiefly to bread and milk as his diet. CAPT. ROSS, OF THE BRITISH NAVY. It is sometimes said that animal food is indispensably necessary in the polar regions. We have seen, however, in the testimony of Professor Sweetser, that this view of the case is hardly correct. But we have positive testimony on this subject from Capt. Ross himself. This navigator, with his company, spent the winter of 1830-31 above 70° of north latitude, without beds, clothing (that is, extra clothing), or animal food, and with no evidence of any suffering from the mere disuse of flesh and fish. HENRY FRANCISCO. This individual, who died at Whitehall, N. Y., in the year 1820, at the age of one hundred and twenty-five years, was, during the latter part of his life, quite a Grahamite, as the moderns would call him. His favorite articles of food were tea, bread and butter, and baked apples; and he was even abstemious in the use of these. PROFESSOR FERGUSON. Professor Adam Ferguson, an individual not unknown in the literary world, was, till he was fifty years of age, regarded as quite healthy. Brought up in fashionable society, he was very often invited to fashionable dinners and parties, at which he ate heartily and drank wine--sometimes several bottles. Indeed, he habitually ate and drank freely; and, as he had by nature a very strong constitution, he thought nothing which he ate or drank injured him.
