NEW YORK, 20 December, 1905.
My dear Professor Haeckel:
I have just received your very kind letter of November 29th, also letter from Wilhelm Bölsche of December 4th in regard to the reproduction of our illustrations of the extinct mammals and other vertebrates of North America. I wish it were possible to comply with his request, but I am reserving them for a popular publication of my own on the extinct vertebrata of North America. As soon as this work appears they will be liberated, and perfectly free for all scientific men to use or reproduce in any way they like.
As you can imagine many of these illustrations have cost me a great amount of study and reflection, and I naturally desire to publish them myself.
In the meantime, however, I have considered them of so much interest to scientific men generelly, and especially to zoologists, that we issue them in large promide form to various museums, the right of reproduction being reserved. I send you a catalogue of these restorations with addition in typewritten form of some which we have just completed. They are reproduced in more perfect form than those in the Munich Museum, and I should be very proud indeed to havesome of them represented in your Zoological Muesum at Jena. ||
We are beginning to prepare for the meeting of the Zoological Congress in 1907, which will open in Boston and conclude its session in New York, and you are one of whom we most earnestly desire to have with us, so I trust you will certainly reserve August and September of 1907 for a visit to America. You will be astonished and delighted with the progress which we have made here in the last few years.
Believe me, with warm regards,
Very sincerely yours
Henry F. Osborn
Professor Ernst Haeckel.
