SECTION II. 



SECOND CLASS. MYRIAPODA, (Gr. fiv^log, murios, innumerable ; 

 novg, pous, a foot.) 



The Articulates of this class occupy a position between in- 

 sects and worms. They agree with the Annelidans in the 

 lengthened extension of their trunk, in the similarity of the seg 

 ments from one end of the body to the other, and in their cylin 

 drical form. They, however, have more complete eyes than 

 any of the Worms ; and in their breathing apparatus and other 

 parts of their organization, are more like the Insects. From the 

 latter they differ in the absence of wings, and in having the body 

 divided into a series of segments, each of which is provided with 

 a pair of legs.
