THISis a thoroughly revised edition of a text that has been well received since 1942. "This book is designed for introductory college courses in general chemistry where there is a restrictive limitation in the time assigned to the work." Anyone who is teaching such a course should seriously consider this text. The 0 NUTRITION AND CHEMlCAL GROWTH IN textual material is neither highly elementary nor so extensive CHILDHOOD.
