fuging the substance and thus driving out all material other than the 
purely colloidal, he found that much better results were obtained. 
With this centrifuge, also, he was able to secure albumen-free milk. 
He likewise found that if he took vegetable material and centrifuged 
it, both the water and soluble material could be thrown out, the 
residue being perfectly dry. Dr. Friedenthal has centrifuged 
finely powdered vegetable material for use in making a vegetable milk 
or vegetable solution, which he substitutes for animal milk in feeding 
infants in an infant asylum in which he is interested. 
In discussing with him the question of the active mass of proto¬ 
plasmic tissue, I found that he believes the body is in part a machine 
and in part living protoplasm. He thinks that all contractile sub¬ 
stances form a part of the machine and that if he could only determine 
the metabolism of the living matter he would find the same metabolism 
per kilogram regardless of whether the measurements were made on an 
elephant, a man, or a rabbit. If curare is used it would prevent 
muscular activity. It occurred to me at the time that it might be 
interesting to see what the metabolism per kilogram is of the eggs of 
the snake, the turtle, and the ostrich. 
Dr. Friedenthal is one of the most interesting men I ever met. 
He is peculiar in his ways and contentious. In fact, he is con¬ 
sidered as altogether too argumentative and contentious in the meet¬ 
ings of the Physiological Society. He has had several clashes, I 
understand, with Hubner. On the other hand, he certainly is a most 
original thinker and well worth visiting.
