The individual carpals and epiphyses in the numbered hand opposite are numbered approxi-mately in the order in which their ossification begins: 1, capitate; 2, hamate; 3, distal epiphysis of the radius; 4,* epiphysis of proximal phalanx of the third digit; 5,* epiphysis of proximal phalanx of the second digit; 6,* epiphysis of proximal phalanx of the fourth digit; 7, epiphysis of the second metacarpal; 8, epiphysis of distal phalanx of the first digit; 9, epiphysis of the third meta-carpal; 10, epiphysis of the fourth metacarpal; 11, epiphysis of proximal phalanx of the fifth digit; 12, epiphysis of middle phalanx of the third digit; 13, epiphysis of middle phalanx of the fourth digit; 14, epiphysis of the fifth metacarpal; 15, epiphysis of middle phalanx of the second digit; 16, triquetral; 17, epiphysis of distal phalanx of the third digit; 18, epiphysis of distal phalanx of the fourth digit; 19, epiphysis of the first metacarpal; 20,* epiphysis of proximal phalanx of the first digit; 21, epiphysis of distal phalanx of the fifth digit; 22, epiphysis of distal phalanx of the second digit; 23,* epiphysis of middle phalanx of the fifth digit; 24,* lunate; 25,* trapezium; 26,* trapezoid; 27,* scaphoid; 28, distal epiphysis of the ulna; 29, pisiform; 30, sesamoid of adductor pollicis (the sesamoid of flexor pollicis brevis is visible through the head of the first metacarpal, just below the numeral 2 on the epiphysis of the proximal phalanx of the thumb). * Irregularities in the order of appearance are most apt to occur in those centers indicated by as-terisks.
