Dear Professor Haeckel,

Dear Sir,

As it is now nearly a year since we issued the 1st Part of your „Evolution of Man” in Cheap Reprint form, and we agreed pay you 1,000 marks within a year of publication, I have pleasure in enclosing a cheque for £50. The total outlay on the work was necessarily heavy, and has not yet been recouped. We have sold nearly 50,000 copies of the 1st Part; but not so many of the Second. The book continues to sell steadily. A formal acknowledgement of the cheque in due course will oblige.

Yours truly,

Charles E. Hooper, Sec.
