My Dear Haeckel
What is the prospect of getting the Radiolaria out this year? You must now be near the end of the introduction, and I suppose you will soon forward the index.
I would like also to know what || about the Report on the Siphonopora. I could give you till the beginning of April or May for this report but this on the condition that all the plates and manuscript shall be ready for certain by that time say 1st of May. Let || me know what the size of this siphonophora report will be in plates and M.S. and if you can undertake to finish it by May.
I must send in a final report and estimate the end of this month so I wish as full information as you can give.
With the best || wishes to your family
Yours sincerely
John Murray
