Persons on vegetable diet have been remarkable for longevity. The first Christians practised abstinence from animal flesh, on a principle of self mortification. Other instances are, Old Parr 152; Mary Patten 136; A Shepherd in Hungary 126; Patrick O'Neale 113; Joseph Elkins 103; Elizabeth de Val 101; Aurungzebe 100; St. Anthony 105; James, the Hermit 104; Arsenius 120; St. Epiphanius 115; Simeon 112; and Rombald 120.

Mr. Newton's mode of reasoning on longevity is ingenious and conclusive. "Old Parr, healthy as the wild animals, attained to the age of 152 years. All men might be as healthy as the wild animals. Therefore all men might attain to the age of 152 years." The conclusion is sufficiently modest. Old Parr cannot be supposed to have escaped the inheritance of disease, amassed by the unnatural habits of his ancestors. The term of human life may be expected to be infinitely greater, taking into the consideration all the circumstances that must have contributed to abridge even that of Parr.

It may be here remarked, that the author and his wife have lived on vegetables for eight months. The improvements of health and temper here stated, is the result of his own experience.
