Gentlemen:
On April 24th, 1928, at 4.pm. I visited the
Orthopedic Hospital in Orenge with Dr. Reotor and examined the
xray films of the following individuals supposed to be suffering
from radium poisoning as a result of pointing brushes on the tongue,
said brushes being used in applying radioactive substances on
watch dials. Previous to examining these films I had had ex-
perience with one case (Miss Eckert who later worked for L. Bam-
berger Co. ) but who it wes found worked in the same way pointing
the brushes on her tongue. I was therefore prepared for the de-
tection of the bone changes shown to have existed in these five
gases. In as much as these are among the earliest discovered who
have suffered from this affliction and no great number of cases are
at hand for comparative study, it is not easy without the history
of radium poisoning, to state definitely what the bone changes are
due to excepting that the bone changes do not conform exactly to
those found in any other known disease.
In these lesions we find irregular increase
in bone density going hand in hand with erosion in other portions
of the same or other bones and a collapse of some of the bones
subjected to pressure viz: the vertebrae. The hips which are
subjected to pressure by weight bearing show more or less erosion
of the articular surfaces of the femurs while at the same time
we find irregular white lines in the adjacent portions of the
femur and ischium (a part of the large pelvie bone). It is reason-
able to think that radiumwhichhas become permanently fixed in the
endothelial structures of the bone first produced a mila (but
constant) stimulation which resulted in striations of new bone of
greater density than the normal, and that es time goes on and the
radiation is forever acting the bone undergoes atrophy with ultimate
collapse most notable in those locations on which pressure is born.

partial destruction of the articular surface of the remur in the
right hip joint, the cartilage space being normal. Below the
articular surface above mentioned the bone showed inoreased den-
sity. There were a few soattered shadows of increased density
in the left ischial tuberosity and the left femur, the latter
occurring in upper shaft and neck. The left ankle films showed
