It is thought by many that “stamina” can only be maintained upon a diet derived largely from flesh, but this is not at all the case. In the chapter on the experience of nations and individuals, I shall adduce a considerable quantity of evidence tending to show that a _greater_ amount of endurance can be secured upon a vegetarian than upon a mixed diet! But many persons do not mean by the word “stamina,” endurance alone. It is often difficult to get a definition of this word, as it varies with individual conceptions. If, however, by “stamina,” is meant stoutness of person, and fullness of blood, such “stamina” constitutes the very food of disease, and the person in such a state is not only more liable to febrile and epidemic attacks, but is also in much greater danger while labouring under them, than one whose development is such as to allow all the secretary functions to be performed with ease, and whose blood is not so charged with either natural or extraneous elements. How frequently do we hear of those who are said to be looking well and healthy being suddenly cut off by apoplexy, or some malignant disorder! The fact is, we are deceived by appearances, by what we erroneously consider the indications of health; for those whom we are taught to regard as healthy and robust are generally the farthest from safety, and only need a slight exciting cause to bring on a fatal disease. It is not the apparent disease which is the real cause of death, but men die because the body is worn out; the tone of the fibres is destroyed, and the principle of motion fails. The obvious disease is the mask under which the condition is concealed. I have referred before to the protection against epidemics afforded by a strictly hygienic life, and particularly by the vegetarian diet. There is an abundance of testimony on this point to which it is impossible to more than refer. Bush, in his “Works,” vol. iv., p. 55, observed that the negroes of the West India Islands, were at that time almost wholly exempt from yellow fever, which cut off the resident upper classes in large numbers. Mr Hardy, a noted Scotch philanthropist, escaped the yellow fever in New York, he asserts, by his course of living; while Mr Whitlaw, of New Orleans, Dr Rush, of Philadelphia, and Dr Copeland, also assert that they escaped yellow fever by abstinence. The poet Shelley, in his “Vindication of Natural Diet,” p. 18, says:
