In the test of 2059 the expaiision on the cross is verysmall indeed; the expansion did not change by more then the v/hole test. Clearly, this result can not be true aridvie may conclude from the tests of 2051, 2052, 2053 and 2054that the expansion on the cross is greater than on the as to the relative amounts of the tYio expansions cannot be drawn from such meager data. 16.
