this point of view	26
to show that the	26
referred to in the	26

in the same manner	26
a paper on the	26
the distribution of the	26

as soon as i	26
thank you sincerely for	26

to hear what you	24
i should not have	24
quite new to me	24
does not seem to	24
be so kind as	24
in the midst of	24

the conclusion that the	24

i am sure it	17
am delighted to hear	17

so far as i	16

the greater number of	16

wallace to charles darwin	16

origin of species is	16
of the life of	16
to suppose that the	16
he goes on to	16
in the journal of	16
in the development of	16

in the sense of	16
i have been particularly	16
it is evident that	16
one and the same	16

am delighted that you	12
introductory essay to the	12
that i could not	12

which you have taken	12
seems to me rather	12
a subject on which	12
a monograph of the	12

only two or three	12
i am astonished at	12
in the third edition	12
in speaking of the	12
the number of the	12
the remainder of the	12

it is not to	12

i owe to your	12

the fact that he	12

not believe that any	12

i am able to	12
charles darwin to miss	12
