l. These elements are not found equally distributed in the parts of plants and animals. In seeds they are found chiefly in the outer layers or envelope which is commonly rejected as bran. A certain vitamine especially concerned with growth and development, the fat soluble B, is found in the green leaf along with lime and iron, all of which are deficient in seeds. Roots especially supply an abundance of alkaline salts which are highly necessary to balance up an excess of mineral acids found in seeds. Ignorance respecting these highly important facts has been responsible for a great number of failures in attempts to adopt a non-flesh dietary. A diet consisting of cereals and fruits, as for example a bread and fruit diet, while apparently satisfactory for a brief period, must inevitably result in failure because of lack of lime, iron and special vitamines found in the green leaf. The same deficiency exists in flesh foods. The soft parts of an animal, fat and lean meat, are almost wholly lacking in lime and vitamines. They contain a great excess of mineral acids. Even a carnivorous animal fed on such a diet soon shows evidence of failure. The lime in the animal body is found almost wholly in the bones, and the vitamines are concentrated in the liver and other glands, so that in the case of flesh foods, as well as vegetable foods, for complete nutrition it is necessary that the whole animal or its essential parts should be eaten. Wild carnivorous animals do this as do also wild men who live largely upon flesh foods. The cave men crushed and ate the bones of the animals upon which they fed, and the Indian tribes of Texas and the Northwest have long practiced the grinding up of the bones of fishes to eat with their food. Dr. Treves, one of London's most eminent surgeons was called upon by the head keeper of the animals of the London Zoological garden for advice respecting the condition of the lions. It was noted that the cubs bred in captivity were club-footed and variously deformed, and in many cases were either born dead or survived but a few weeks. His investigation showed that the fault was wholly in the diet. The lions received only the soft parts, lean and fat, of animals. When given bones and bone meal the difficulty speedily disappeared. Stefansson reports that, when living upon an Eskimo diet it is necessary to take the whole bill of fare, including the raw frozen liver of the seal, otherwise serious illness interv
