Raises a question about a statement in Orchids; his observations differ.

Is confirmed about the bending of the fly orchid pollinia. [See "Fertilisation of orchids", Collected papers 2: 141.]

Describes work with pollinia of another Orchis species.

Sends a paper he has written [on scarlet runner].

Encouraged by CD’s reply. Sends another paper, on blue Lobelia.

Asks advice on books.

Sends an addition to Lobelia paper; admires adaptations for fertilisation.

Wonderful how every flower one looks at is explained by, and throws light on, the fertilising process.

Delighted with mechanisms of Salvia and Viola. How can anyone who compares structure of Viola cornuta and common violet still suppose them to be separate creations?

The conversion of Asa Gray must be a pleasure.

CD’s doctrine accounts for and gives a vera causa of structures.

Discusses F. Hildebrand’s book.

Thinks CD’s views of insect agency and crossing might explain structure and variations of papilionaceous flowers. Lists five points. Asks CD’s opinion.

Thanks CD for advice to watch the action and not only the structure [of plants].
