[165]
Each genus, each family, radiates from a centre & if it were required to draw the characteristic parts— instead of describing them by languages, it would I think be necessary to give type (as in family order) of Hawks & then give the extreme variations in different lines — in the f. beetles-hawk — carrion-vultures – [illeg] &c &c.— —
shows if we had to describe by drawing a race of men— we should take type: & deviations.—
— This puts the non-linearity of nature strongly.—
