PARIS. FRA. CB Société Scientifique d*Hygiene Alimentaire. Although my visit to Paris in 1907 had not "been especially productive in the acquisition of new material or new ideas for the la¬ boratory, I thought it. desirable to inleude it in this trip, as I felt, that more than six years ras too long a pe riod to elapse before making another visit and getting into touch v;it.h the physiologists vho were working there. This desire was strengthened by a visit of Professor Babriel Bertrand to the Nutrition Laboratory in the fall of 1912, when he told me that the Société" Scientifique d'Hygiène Alimentaire contem¬ plated the construction of a laboratory for studying the problem of nut¬ rition. This society had commissioned Professor Bertrand to visit the Nutrition Laboratory with a view to inspecting our respiration calori¬ meter and Judging of its practicability for their new laboratory. Prof¬ essor Bertrand spent a day here, making many inqxiiries in regard to the cost of building such a calorimeter aid the scientific staff necessary for the proper conduct of calorimeter investigations. He took away with him many sketches and subsequently pxirchased a number of photographs of dif¬ ferent parts of the apparatus. According to Professor Bertrand, the leading spirits in the society were Professor Armand Pautier, LT. Roux of the Pasteur Institute, ü. Alquier, the secretary, ar.d several others whose names I do not now- recall. Before going to Paris, I had received letters from several of these gentlemen, stating that they would like to see me to discuss the problems and plans which had been suggested for the society. The first formal meeting with these gentlemen was at a luncheon given by Dr. Roux
