 composite — the fingers to the bicomposite — spine 

 (§ 84). The bones of the arms and legs would 

 then be the consolidated masses of these sets of 

 five ribs. 



To avoid confusion, where speaking of man and 

 animals under the same head, we shall call both 

 fingers and toes " Digits,'' and number them begin- 

 ning with the thumb or great toe, frst, second, third, 

 fourth Sind Jifth digits. 



If the third digit (" middle " finger or toe) repre- 

 sent the centre of this S, the fourth and fifth digits 

 will receive their impressions from the rear C, the 

 first and second from the front C, and the central 

 one from both. Indeed we may go further and say 

 that the fifth digit represents the posterior part of 

 the rear C, the fourth the anterior part, the second 

 and first the same for the front C. Then (§§ 25, 92, 

 96) the fifth digit receives its impressions fi'om the 

 formation of the secondary section of the anterior 

 winding hne, the second from the estabHshment of 

 the primary section of this line,. the /owr^A digit 

 from the establishment of the primary section of 

 the posterior winding line, and the frst from 

 the formation of the secondar}^ section of that 

 line. They will, also, in these connections be re-
