This book relates the experiments of Dr. Metheny on breathing capacity and grip strength. The study is divided into four sections, namely, (1) Problem and Data, (2) Breathing Capacity, (3) Grip Strength and (4) Health Relationships. Each of these sections is fully discussed, with excellent charts and illustrations. At the close of each section is a complete summary. Dr. Metheny describes some new designs for the spirometer and the dynamometer which permit high reliability in measurements.
Grip strength and breathing capacity determinations were done on some 169 children from 2½ to 6 years of age. The results of these tests were analyzed in relation to anthropometric measurements. The grip strength was found superior in girls. No difference was noted when children were compared from the social and the mental standpoint.
Dr. Metheny's work does suggest that prior to the onset of a cold there is a decrease in strength and
