Instructs JDH on how to pollinate Leschenaultia.

Evidence of Leschenaultia and the dioecious condition of cowslips and Auricula is making necessity of insect pollination "clear and clearer".

Thanks JSH for his defence [see 2794].

He is not hurt for long by what his attackers say. His conclusions were arrived at after long study. He has certainly erred, but not so much as "Sedgwick and Co." think.

Asks JSH to send names of plants that vary greatly in length of pistil.

[Form letter] Wishes to nominate JH as member of commission to prepare for International Statistical Conference meeting in London in July.

Glad to hear JH feeling better. Enclosing a 'shorter and simpler' explanation of some experiment by Léon Foucault, asking for comments.
