The lecturer first spoke OF the mistakes OF the earlier
naturalists in their classification OF animals grouping
them according their external structure. Then pass
ing to the cassfcaons OF Cuvier, he described the
creatures called artcuates. There an immense
number of animals whose bodies distinguished by
being divided into rings segmens, OF which the COM

group crusacea Of which the lobster crab and
shrimp were examples. These differed from the lowest
forms in having legs, and it would be found that all
their appendages the claws and the protruding
eyes, only modified legs. Among these and the
insects of the typical segments were united; IN

OF the forward rings the insects this union formed
the head thorsx and abdomen. These differ from the
worms in having jonted appendages
