[179]

Though with Cuvier (& Huxley) this enunciation of general proposition may be main end of Classification, & the distinction between a natural & artificial system be that all characters are included in former, yet I think by very many systematists it has been silently felt that something more is meant.

— Show this — Anyhow if more can be included in a classification which will group [illeg] resemblance it will be felt as advantage; & this is case if we include make genealogy the basis,

[179v]

it will necessarily include resemblance, from generation curious that — it is useless to say Bear dog might descend from Cow & wolf from marsupial— we imply an absurdity.— 11

Put it this way — But on our doctrine on what does resemblance depend on community of descent — unlikeness or resemblances of descent — so that in our view [illeg] genealogy is included. —as cause & effect & it throws light on some of above difficulties in those who look at classification as something more than mere collection of resemblances who include causation in their classification.
