Dear John:
Thanks for your letter of November 27, 1956, with the
attached tables of data on the post Redwing surveys.
In studying the tables we notice ths omission of the
wet weight data and calculations for Sr?”
and calelum for
samples 4047-4054,
Since we do not have the wet weight of the samples sent
you, as I mentioned in the telephone conversation, we have
calculated the wet weights from the data we have avallable.
The calculation was made by taking the difference in welght
of the samples we have from our original dry weight samples
to get the dry weight of the samples sent to you and then
multiplying this dry weight by the conversion factore to
obtain the wet weight of the samples sent to you.
is a table showing "Weights of Samples Sent to NYOO
Enclosed
August 10, 1956."
We notice a difference for aample #3815 on the two sheets
of x 100 and wonder if a decimal point is out of place.
