TRANSFORMA TIONS OF INSECTS. 
in their movements. They evidently were greatly affected by it, 
and seemed to shun it instinctively. This was the first marked 
exhibition of instinct, and then locomotion was performed with 
the same instinctive care. The end or anal segment was expanded 
like the same part in a caterpillar ; and, being first attached, like 
a true pro-leg, and its steps, as it were, measured, its body was 
carried forward by an effort that extended, as in insects, from 
segment to segment. 
At twenty-four hours after escaping from the membrane the 
young animals were lying together in a heap, but when disturbed 
seemed to have acquired more power of moving ; they remained 
quiet except when roused, and had not yet taken food. The 
only marked difference in their appearance, excepting that they 
had still further increased in size, was in the nipple-shaped 
protuberances on the sixth and seventh segments, the rudiments 
of future legs. These were now more distinct and more uniform. 
Ten hours later in the day they assumed still more the appearance 
of nipples projecting from the under surface of the segments. 
When examined in specimens that had been placed in spirits of 
wine it became evident that these projections were occasioned by 
the development under the deciduous (cast skin) integument of 
four new but exceedingly minute legs, complete in all their parts, 
each covered by its proper skin. The claws to the legs were 
also more strongly marked. The new segments were more grown. 
Mr. Newport found that the Myriapods had assumed a darker 
colour on the nineteenth day, but they had not as yet taken 
food. The double pair of legs to the sixth and seventh segments 
were distinct through the external tegument, which had begun to 
be separated from the surface of the old segments, to which up 
to this period it had closely adhered (Fig. 6). The patch on 
the side of the seventh segment had become darker, and the 
new segments were further advanced. On the twenty-first day 
the young Julidoo still remained coiled up and perfectly quiescent, 
with their legs placed side by side along the under surface of 
the body, like the pupae of lepidopterous insects. The new legs 
had increased in size as well as the whole animal, although it 
had not taken food. The animal was still partly coiled up, but 
the skin that covered its body was greatly distended, more
