Laboratory of Animal Physiology, Sorbonne. Professor Lapicque. A visit was made to the laboratory of Professor Lapicque, who is the successor of Professor Dastre at the Sorbonne. Professor Lapicque is one of the most stimulating men that I met. Ho has all the Frenchman’s brilliance and facility of speech, with many ideas. He is just at present occupied in developing the use of sea weed as a food for chickens. The sea weed had been thoroughly washed to free it from salt. In talking with him, I found he was quite sceptical with regard to the term "basal metabolism". He claims that with ruminants such a thing does not exist, as ruminants are always in the process of digestion. He has prepared a curve showing the normal metabolism or food demands of animals of various sizes and shapes when in full digestion. I was much interested to find that he is working upon bran. Everybody in France seems to be working on feeding experiments with bran. In discussing the question of specific dynamic act ion,he claimed that the expression i3 exac tly what Rubner meant. Just what he did mean I could not find out. Madame Lapicque assists him very much in the laboratory. We had the pleasure of meeting her and Professor Lapicque again at their house, along with Professor Sherrington. There was much discussion with regard to the fact that the (lermans had been invited to the Congress in ’Edinburgh, an invitation which the French and Belgians resented very much indeed. The injustice shown in these international arguments can best be brought out by the following illustration. It was argued that Professor Schafer was a derman, bora in dormany, and sympathized with the dermans, and hence had extended an invitation to the dermans. As a matter of fact, he was not a derman, was born in London, during the war did not sympathize with the dermans, and lost two sons in the war.
