In speaking of the radium emanation experiments made formerly by
Staehelin and his associates in the His clinic Professor Hunts said he
felt that they were useless. In commenting upon the article presented
by Fleischmann at the Berlin Physiological Society, in which Friedmann
spoke about fever and pituitrin, Hunts remarked that he was astonished,
as was I, to have him refuse to report how the solution was made
albumin-free.
Zuntz considered Haldane very clever and made many interesting
comments as to his absent-mindedness and his devotion to his pipe.
He said that Haldane always lighted his pipe as soon as he left his
room to come downstairs.
Zuntz saw Douglas on Teneriffe and got a very good impression of
him. He was by no means satisfied with the Haldane carmine titra¬
tion, although he saw Douglas make the titration a hundred times on
Teneriffe and not get a red color. In discussing the Haldane titra¬
tion method he said he disliked the way in which Haldane pricked his
finger and then shook it. He asked Haldane if he had ever seen a
needle and as he said he had not, Zuntz sent him one. In his method
of titration Haldane uses but 6 to 7 drops of blood and yet finds
carbon monoxide and oxygen in the blood to 20.73 per cent, i.e., four
figures, but really can determine only one part in six or seven.
We spoke of the question of the secretion of oxygen and Zuntz
thought it was not true that there is such a secretion. He believed
that during work carbon monoxide is not in equilibrium, for some of the
blood must be almost oxygen-free during severe work and only in work
does Haldane find that a secretion of oxygen takes place. Zuntz
also believed that carbon monoxide may actually be absorbed by the
lung tissue.
In discussing the Douglas bag method Zuntz said that it was simply
