Reports of Visits to Foreign Laboratories, vol. 4 (1923) [Illustrated Typoscript in 7 volumes] Reproduced with the kind permission of Dr. Cecil E. Leith
Benedict, Francis Gano
I found the group of physicians keen and unusually interested in the 
metabolism work of the Laboratory. There was* however* absolutely nothing 
in the nature of metabolism experiments going on in Geneva. 
Opportunity was taken while there to look into the reouest made by 
the library of the League of Nations for books and reprints. I found the 
request had formerly come fron a clerk who was not at this time connected 
with the League of Nations, and no one seemed to know anything about it or 
to have any particular interest in having our publications, so 1 decided 
it was unwise to send them until further demands were made. 
Berne* Switzerland. 
University of Berne (Physiological Institute). 
Professor Asher and Professor Abelin. 
In Berne naturally the first place that I went to was the laboratory 
of Professor Asher, who was at that time in America and, indeed, almost at 
that same date was visiting the Nutrition Laboratory lie re. In his absence 
Professor Abelin showed me every courtesy, and Mrs. Asher, who has helped 
her husband a great deal, came to the laboratory and showed us courtesies 
in every direction. The matter of chief moment and interest to me in Berne 
was the technique of experimenting on the white rat, which has been brought 
to a high degree of perfection by Professor Asher and his associates. The 
method employed is the Haldane principle of weighing the animals in the 
chamber and determining the oxygen consumption by weight. Inasmuch as I 
first thought that this method might have many advantages over the closed- 
circuit method employed by the Laboratory in the research at Columbia 
University, I gave special attention to studying the technical details of 
this method and inquiring as regards its control and accuracy. The weighing 
chambers are of glass, with ground glass joints. The absorbing vessels 
usually are glass tubes containing soda-lime and sulphuric acid with pumice 
stone or beads. No provision was made for recording graphically
