— Total number of species in the orders which are unfavourable when divided equally & these are 6444/15,645 of whole ie between 1/2 & 1/3 of whole

Moreover in the other orders the excess of ~~small~~ gigantic genera is but small, so that we see that the varying diminishes at two poles. —

Of the largest genera pick out in each order ~~about~~ ~~1/3~~ 1/2 of the total number of the to half, (omit Solanaceæ) & then compare that, when added up, for whole volume with the 2595 specs belongs to genera with 10 & under; to see if biggest genera vary less —
