difficult — yet suggested. (vipers tooth also a difficult), the whole mind is constituted that a difficulty makes greater impression, than the grouping of many facts with laws & their explanation will probably reject this theory — (I must answer it by rooting out curious cases of intermediate structure, & supposing much extinction. give a parallel case)

Waterhouse remarked, that any argument for transmut, from one organ graduating into other is lost, be (as vertebræ into skull, two bones of tibia into one. —) because if the animals were taken from which these series were drawn they would not be intermediate, but this is not required. —

Waterhouse says perhaps animals of Fernando Noronha are found on unknown coast in front of it. —

Cuvier has grand sentence about the Animaux fossiles — being a mere fragment of the discoveries to come — Owen in his description of my fossils makes same such remark & before the conclusion of his work — Lund makes his wonderful discoveries = negative facts are valueless = monkeys =

Owen has described a greatt Struthonidous Bird from New Zealand — so not an Apteryx, yet it shows the Apteryx is not quite isolated in its present locality — there have been at least other birds, with small wings, & surely the Apteryx is more closely allied to the Struthonidae than any other forms —

In S. America. it appears from Lund more Mammals, than at present

in Europe we know there has been several successions of Mammals. —

yet only two monkeys, there are now have been found fossil in S. America, there are now — — species in S. America. — so see what a mere vestige, is preserved in this country — same argument to India & Europe — & Africa!, — any negative argument against — monkey-man, valueless. —

May not several generations have been confounded in the caves?

It is highly important, to bear in mind that enormous periods may elapse, even in situations apparently favourable for the preservation of shells; where land broken, rivers entering. — & yet no shells — now look

at Scotland — coasts of Chile, excepting Concepcion — Patagonia — Beds of La Plata. (except close to B. Ayres). — If we may take this as guide, the shells preserved must be as much a casualty as, bones of Mammalia in caves: — argue first case of bones (New Red Sandstone) & then go on to shells —
