latter part of its subsequent transformations, the 

 absorbed oxygen permitting then of a production of 

 heat, and causing also considerable diminution in 

 weight. Having thus put in order the cell con- 

 taining it, the larva remains for some little time in a 

 condition of quiescence, and now, under the new 

 name of chrysalis, pupa, or nymph (N, Fig. 4), enters 

 upon the sequence of transformations, all slowly and 

 quietly effected, which end in converting it into a 

 new creature. Constrictions occur, and rings or 

 segments vanish, until the body becomes head, thorax, 

 and abdomen. As it lies upon its back, prominences 

 begin to show themselves, which become more and 

 more pronounced, until, at last, they sufficiently assume 

 the form of legs to be recognised ; these are six in 

 number and are much more than organs of loco- 

 motion, as they bear, curiously disposed upon their 

 many joints, a whole set of tools singularly varied in 

 modelling and application; a tongue, too (t, Fig, 4), 

 replete with wonders, and lying stretched along above 

 the body, begins to be seen ; and then, drawn round 

 from the back of the thorax, like a girl's cloak which 

 she has allowed to slip from her shoulders, are gauzy 

 but many-folded extensions, which hereafter become the 

 beautiful instruments of flight {w, Fig. 4). But these 

 external changes, marked though they be, are trans- 

 cended by the wonder of the progressing interior modi- 

 fications and developments. The nerve system is recast 

 and enlarged, the digestive apparatus changed, an 

 entirely new set of muscles and tendons brought into 

 existence ; glandular structures make their appearance, 

 breathing tubes or trachea in untold number come into
