from the hishn sain (4x) recordings.
Because of the increase
in resolving power some lines which were unanalyzable or
undetectable on the standard gain records became analyzable
on tne nich sain records.
The data have been left in tabular form to make the
information more readily accessible to those who wish to use
it.

In actual practice tne analysis is more difficult than
Might be assumed from tne description in the Analysis of
Data section for tne following reasons:

For tnis reason a straight line is use3 for the
