like to know whether the mentioned parallelism between molecular volume (as is
measured, for example, by Van der Waals’s b constant) and combustion heat is at
all a postulate of our modern views on molecular theory, or whether it is also pos-
sible to conceive of cases in which relations are reversed. Is there any literature in
theoretical physics on this question yet?
In giving my most obliging thanks in advance for the kindness of eventual con-
sideration of my problem, I am, in great respect, yours very truly,

The whole business is a matter of indifference to me, along with the clamor and

strongest means available outside of the courts, threatening in particular with a
break of relations. By the way, M. really is preferable to me than Lenard & Wien.

Such an admirable person!

I’ve been living all week with Kamerlingh Onnes’s brother, an
excellent painter who lives in a fabulously furnished home, has a son, who is also
a heaven-blessed painter, two very nice daughters and, it goes without saying, a
