Study of Rats Valuable.

After 11 years of experimenting with rats, Dr. E. V. McCollum, head of the chemistry department of the school of hygiene and public health of Johns Hopkins university, has reached the conclusion that the food requirements of all animals, including man, are the same. He declares that the extensive consumption of dairy products is necessary to produce a vigorous race and prolong life. During the years that Doctor McCollum has been studying this question, especially interesting now, when food is playing such an important part in the affairs of the world, he has been housing about 1,500 white and hybrid rats in his laboratory.
