A radiological investigation of the ossification and maturation of the carpal bones in 1,360 East African children of known ages has been described. The work has revealed that there is no difference in the order of appearance of the carpal ossification centres from that : commonly accepted for other races. The fact that skeletal maturation is more rapid in girls than in boys has been confirmed. The rate of skeletal maturation has been compared with findings of other writers on American children, and the African children investigated have been found to be from 11/2 to 2 years behind present American standards.
