One is astonished at animals, although adapted to very diff. habits; although bearing much great general resemblance, being formed on same type — Bats wing & paddle & man's hand — (NB animals not having great general resemblance, are not built on same structure, mole & m. cricket swallow & dragon fly) on my theory, if such

[14v]

allied animals, having descended from one parent, & having varied like varieties, without some actual cause, it would be marvellous if they were not built on same type — one may shorten, lengthen &c bones of hand, but far greater step

[15]

to alter whole relations of bones although that is possible — as we see in Icthyosaurus— (This had better begun, if my theory be true, & animals possessing many general resemblances, be descended from &c, then & now)

Consider how many other ways of catching insects on wing — Bats swallow, swift— [illeg] fly-catchers Hawk & Woodpecker. Dragon-Fly

[16]

If then then then in each animal, traces of the changes each organ has undergone — anchylosed bones vertebræ crania leg bone = plants —

─If laws of change be as I show, then peculiarities descend not useful— abortive organs—

[16v]

insects mouths — crustacea do although it may have required the examination of many insects to discover that proboscis of Bee Butterfly essentially consists of — — pincers representative of Beetles jaw — yet we here see looking only at the bee, that the organ could not have been made for part
