Dear Sir

As a very humble worker in Zoology & as one of your greatest admirers for your immense services to science in general & to mankind, permit me to offer you my best wishes for the coming year.

You are to Europe what Professor Huxley was to us in England & I hope you may long be spared to continue your work.

Yours most sincerely

Macleod Yearsley

Professor Ernst Haeckel.
