that those who are feeding on "polished rice" can be prevented from acquiring the disease "Berri-berri" by mixing rice "outsides" with the polished rice. The study of the subject has gone further. A crystallizable substance allied to proteids has been separated by the chemist in quite minute quantity (one part by weight in 10,000 parts of rice) from the outer coat of rice grain, and is called "vitamine." It is this substance which prevents the "whole" rice grain from causing "Berri-berri" in men and birds who feed on it, and it has been shown experimentally that it prevents the development of "Berri-berri" when taken with "polished rice," and cures it when administered to man or bird suffering from that disease. This case calls to mind the popular notion that the indigestion caused by eating a "peeled" raw cucumber can be prevented by eating some of the dark-green "rind" or outside of the cucumber. I do not know that anyone has ever shown that this is a true doctrine, but it serves as an illustration of what has been demonstrated in the case of rice grains and "Berri-berri." Here, then, again we have, in the case of rice, a minute quantity of a substance naturally present in an article of food when taken in its natural normal condition, which is destroyed and removed by the ignorant manipulation of man, although necessary and essential if that article of food is to serve as healthy diet. In this case (as so many others) it is the attempt of greedy traders to make money by giving to a worthless spoilt article the appearance of the regular and valuable article, which has led to disease and disaster. It becomes more and more obvious that the selection of articles of food and the whole question of what is a healthy diet, are not such simple things as is often supposed. Here, as in everything we do, we must either keep to the long-established habits sanctioned by Nature, or we must have full and detailed knowledge to guide us in new ways, so that we shall not recklessly blunder by ignorance into disaster and death. The "feeding" of man and of his herds requires new and continued investigation. Old convictions and traditions in these matters must not be lightly thrust aside by the possessor of that little knowledge which is a dangerous thing. Meanwhile, for the civilized man the advice of Pasteur's pupil and successor, the late Professor Duclaux, is noteworthy: "Do not eat much, but eat many things; there is safety in variety, danger in uniformity."
