that Br. Comar's results showld be given the strongest weight,
nanely that in the exchangeable caleiua and strentiua,
The
ratio of that exchangeable material would be wery sintler to
what you get in the bones, the reason being that the par-
tdoular sites on these olay particles are ideal for the ionte
radius of calcium and, therefore, as far ap bese exchange is
concerned, you would expect an enrichaent in faver ef exiciua
on the surface of the elay particle, whieh would reduce it
to the erder of 1 to 3 toward the point 3. Since we have
direct experimental ecufirmation that it is taken into the
pone as it is in this source, {t seems to me that's the
maber wa should underline.

Cf course the soil 1s total strontiun againet tctal caloiua,
and your figeres are exchangeable.
KULP:
Yes, I*m saying that if we hed exchangeable, which is net a
hard experiment, that any of ws could do it ih a reasonable
tinue, but the experimental results I would predict would be
eloser to point 3 than it would to three,

Jen't it alse true that you have to use a considerably larger
figare for the strontina than the eamcunt that ectually falls
on an arable ares on a cultivated farm, because you have
to replace all the things that ty fertilized ayeten cr water
you have to replace the things that would pass through, #0
you're really drawing on the rest of the world for the
