Rostock, Germany. University of Rostock (Medizinische Universitäts-Poliklinik). Profeasor Dr. B, Grafe. Since ray la3t visit Dr. Grafe had received a call to go to Rostock from Heidelberg and had established a special laboratory in the Poliklinik, so that I was glad to visit this. It is perfectly astonishing the energy this young man has and what he has accomplished. He has fitted up the laboratory with a Jaquet-Grafe respiration chamber, with a special device for aliquoting with a gas meter, with a small chamber for dogs, and a very small chamber for the white rat. He has a very complicated gear case for getting different rates of ventilation with the aliquoting chamber, from .2 liters to 45 liters per minute. Bo also had a very good gas analysis apparatus and in general the whole place was fitted up very well. I was much impressed with the intense loyalty and enthusiasm of the three or four assistants he had with him. Grafe was quite inclined to discuss political matters rather exten¬ sively, but we were able to discuss certain scientific matters. He was apparently very much affected by the criticism that was raised against his work and Graham’s in our Publication 280, although he expressed nothing but appreciation of the friendly way in which we had written. Still, he felt as if our criticisms were entirely unsound. He has been writing a cxrtXj^c^jL. large for Ellenberger's Handbuch (a copy of which has subsequently been A sent to us), discussing this point at some length.
