Asks writer of an article on weeds why he supposes "there is too much reason to believe that foreign seed of an indigenous species is often more prolific than that grown at home?" The point is of interest to CD "in regard to the great battle of life which is perpetually going on all around us". Cites analogous observations by Asa Gray and J. D. Hooker. Does writer know "of any other analogous cases of a weed introduced from another land beating out … a weed previously common in any particular field or farm?"
Glad THH has taken up aphid question versus Owen ["On the agamic reproduction and morphology of Aphis", Trans. Linn. Soc. Lond. 22 (1858): 193–236].

Includes envelope.
