Leipzig, May 6, 1885
Dear Sir [John Shaw Billings],
I am much obliged to you for the sending of the photographics (sic) of crania. The methods of photographing several heads upon the same plate with scale of measure added appears indeed to be of great interest. I have shown these plates to Dr. Emile Schmidt (formerly in Essen), whose collection, embracing 1300 nos. is to be placed in our institution.
I have myself, I am sorry to say, little time for craniological studies, as all my free time is devoted to embryology, but whenever I can help to promote craniology, I do so with pleasure. With regard to the specimens Prof. Braun (spelling?) has already written to you, I presume, that he had made for you a series of sections, ready to be forwarded, simply waiting for your directions. The sudden death of our dear president Panum has undoubtedly grieved you. He was in the position which he filled with so much conscientiousness, as if made for it and would have assisted you in the organization of the Congress in 1887, with his advice.
