Summary

Thanks CD for the copy of Orchids and papers on Linum and Lythrum [Collected papers 2: 93–105; 106–31].

Lengthy criticism of Agassiz’s views on species as stated in his Essay on classification [1857].

Interested by CD’s trimorphism in Lythrum. Thinks some great mystery may lie in the fact that in some genera, some species are tri-, some di-, and some monomorphic, and in other genera, Apis, Vespa, Bombus, all the known species are dimorphic.

His observations come from following CD’s generalisation in Origin [p. 79] on necessity of out-crossing.

Suggests that CL have Murray print a two-volume edition [of the Elements].

Summary
