My dear Barker:
Our graduate student who is working on
radium poisoning in rats has just been in to tell me
that he has again exhausted his supply of radium bro-
mide; and that the rats are still in good, healthy
condition, notwithstanding the heat. I think that he
has given them very careful diet and attention, but
he has now reached the stage where he thinks that it
is advisable to actually kill off one or two of them
to get confirmation of the radium content of the rats,
which has up to this time been determined only roughly
by the gamma ray method. We simply put the rat in a
paper holder and strap it to the electroscope, but this
method gives us only relative results for the instru-
ment has not been calibrated; but by analyzing the
skeletons of a few of these rats we should be able to
get a fairly good calibration constant of the instru-
ment.
This week-end my daughter, Esther, ex-
pects to come home and then we shall be able to make
our plans for the summer. I have thus far been unable
to make any definite plans for vacation because Mrs.
Schlundt has not decided whether or not she should go
up to Mayo Brothers for a thorough examination. She is
still in the resting treatment for heart trouble and
she thinks she is not making very much progress.
I am still hoping that I shall be able to
get about two weeks in Colorado.
Sincerely yours,
Herman Schlundt
Herman Schlundt.
