"Pliny, says that the Essenes of Judea fed on the fruit of the palm-tree. But, however this may have been, it is agreed, on all hands, that, like the ancient Pythagoreans, they lived exclusively on vegetable food, and that they were abstinent in regard to the quantity even of this. They would not kill a living creature, even for sacrifices. It is also understood that they treated diseases of every kind--though it does not appear that they were subject to many--with roots and herbs. Josephus says they were long-lived, and that many of them lived over a hundred years. This he attributes to their 'regular course of life,' and especially to 'the simplicity of their diet.'" THE BRAMINS. The Bramins, or Brahmins, are, as is probably well known, the first of the four _castes_ among the Hindoos. They are the priests of the people, and are remarkable, in their way, for their sanctity. Of their number I am not at present apprised, but it must be very great. But, however great it may be, they are vegetable eaters of the strictest sect. They are not even allowed to eat eggs; and I believe milk and its products are also forbidden them; but of this I am not quite certain. Besides adhering to the strictest rules of temperance, they are also required to observe frequent fasts of the most severe kind, and to practice regular and daily, and sometimes thrice daily ablutions. They subsist much on green herbs, roots, and fruits; and at some periods of their ministry, they live much in the open air. And yet those of them who are true Bramins--who live up to the dignity of their profession--are among the most healthy, vigorous, and long-lived of their race. The accounts of their longevity may, in some instances, be exaggerated; but it is certain that, other things being equal, they do not in this respect fall behind any other caste of their countrymen. SOCIETY OF BIBLE CHRISTIANS. This society has existed in Great Britain nearly half a century. They abstain from flesh, fish, and fowl--in short, from every thing that has animal life--and from all alcoholic liquors. Of their number in the kingdom I am not well informed. In Manchester they have three churches that have regular preachers; and frequent meetings have been held for discussing the diet question within a few years, some of which have been well attended, and all of which have been interesting. Among those who have adopted "the pledge" at their meetings, are some of the most distinguished men in the kingdom, and a few of the members of parliament. Through these and other instrumentalities, the question is fairly up in England, and will not cease to be discussed till fairly settled.
