Dear Stan:
In checking our list of fish samles which you sent
us in early Harch, I find that we have serple numbers
1598 (snails), 1998b (star fish), and 163) (probably
snails) whieh are mot mentioned ci the list. Also,
sample number 737 (helmut) was not reosived.
number 1523 (angel fish) wes not received.
ples were marked 1623.
Sample
Two san-
Will you review your original list and send me the
correct numbers or the identification for tho above.
&s near as I can judge our calculations, our values
for the four snail semples are not more than a factor
of two (2) less than yours.
When you correct for ab-
sorption, the values will probably be considerably
close. At the moment we seem to be in the same ball
park, which is good.
Sincerely yours,
