Has heard WS is publishing an English translation of François Arago's astronomical writings. Urges against including Arago's lectures if the Italian translation is indicative of their level of accuracy. Lists numerous errors in that edition. [Marked 'not sent.'

Pleased that WS included François Arago's lectures in his compilation. Believes the Italian edition could have been better edited. Remarks on the Leviathan problem.

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?"

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?"
