This little book should be of great value to any one interested in the maintenance of a small rat colony. The author describes in considerable detail the problems encountered in regard to size, ventilation, temperature and humidity of the rat quarters. The chapter on equipment gives in many instances the source of purchase and the price. Rearing, mating, growth and feeding of rats are thoroughly discussed. The author's method for the assay of vitamin D in milk is also included.
