made such an impression on me as did Dr. Liljestrand.
Liljestrand had just finished some work with a Dr. Mary Collett on the
question of menstrual cycle, and found two points, maximum and minimum
metabolism. Dr. Collett did not record the subjective impressions and did
not get the pulse e :cept at the beginning and end. I told him of Miss
’Thitalaw, and said that I felt that pain and disL„comfort might have a lot

In discussing the question of the temperature of expired air, Liljesti&nd
thought the average was 32° and not 34° C. He used a mercury thermometer
wrapped in cotton. I suggested he try the string galvanometer also, and
get curves from the whole respiration. I think the temperature of the inspirëd
air is also very important indeed. Subsequently at Edinburgh I was able to
see even more of Dr. Liljestrand, and I can truthfully record that I have
seldom met a young man who lias impressed me more favorably than this very
t
active young Swede. He has a very good mind, has worked in many laboratories
and hence is almost international in his ideas and interests. It is rather
surprising to me that he has not already attracted students, for he is very
capable.

Professor Svante Arrhenius and Dr. Olaf Arrhenius.
I had merely social relations with Professor Svante Arrhenius. He was
much interested in the political and economic situation, and discussed the
war very freely indeed, but did not discuss scientific matters in any sense.
His son, Dr. Olaf Arrhenius, was connected with the Agricultural Experiment
Station in the botany department in the near neighborhood. I had quite a
good deal of discussion with him with regard to hydrogen-ion, and he pointed
