the mercury. Apparently Professor Rietschel was also interested in the 
insensible perspiration of children, for he had one of the typical Sauter 
balances for the child’s insensible perspiration, finished with very 
great elegance and refinement but equipped with the inevitable horsehair 
mattress. This seems to have clung to the whole insensible perspiration 
Grafe related innumerable incidents with regard to Rubner and the 
older physiologists. He pointed out that Pflüger always combatted Voit 
and that Rubner told him that Voit had held up the publication of Rubner's 
paper on the isodynamic law. Rubner was only 25 years of age at the 
time and the paper lay in the drawer for two years. Rubner also told 
Grafe that there was not one idea in Voit’s head. The whole story of 
Pflüger's ego and the dedication of Zuntz' books on high altitudes to Pflüger 
was repeated. Pflüger objected to the simple dedication "E. von Pflüger". 
Zuntz replied that on the Bismark "Denkmal" there was only "Otto von Bismark". 
Grafe also told me that Pflüger was always in controversy with Ludwig and 
that Pflüger was invariably right but Pflüger had no "school" and Ludwig 
had the great school, so his ideas and personality went much further than 
did Pflüger’s. It was interesting to see the relationship between the 
different schools but Grafe, who had been so long at Heidelberg, said he 
thought that Krehl was a very much bigger man than F. v. Müller of Munich 
and he thought that the latter would be wholly forgotten in 100 years, 
but not Krehl. 
Someone, not in Würzburg, commenting on Grafe's dog upon which he 
published his long discussion of the adjustment of the animal to the 
environment and to the different fasting levels, a criticism that I raised 
very strongly in the fasting man book, said that Grafe's dog had an 
enlarged thyroid and that dogs were especially liable to upset' thyroid 
and he felt that this was the case with Grafe's dog. Of course there is 
no means of knowing now, but it is an interesting point in the argument 
against doing too much work with dogs. 
Bohnenkamp. The newest things in Würzburg were the work of Bohnenkamp. 
I had not met him before or at least did not recall having met him. He 
is a most serious-minded, charming chap, a very good man to talk things 
over with, critical but perfectly willing to give and take, a most helpful 
and encouraging man for discussion. One felt perfectly free to talk over 
every point with him and criticize as sharply as one wished and nothing 
would be taken amiss. I was interested in his problem of studying the 
surface area of the body and getting the average temperature of the body 
and all the various steps in his series of papers. For the average 
temperature of the body he used the resistance thermometer. He had a 
"fish line affair" made up of 50 meters of fine copper wire on a reel. 
The subject first removed the clothing and he then wound the wire around 
and around the body from head to foot, in about 1 centimeter intervals. 
In about 50 minutes the temperature is constant with a room temperature 
of 25°. It is important now to emphasize that Bohnenkamp is strong for 
24° to 25° C. One recalls that Rubner did everything at 16° C.
