During the years 1930-32 there appeared three new deflection values of elm, and one new spectroscopic value. All four determinations were mutually consistent and apparently of high accuracy. From them I deduced2 1.75940.001 as the best value of e/m. In other words, the 1929 discrepancy had disappeared, and the error had been shown to lie in the 1929 deflection value. In the succeeding two years three new values of e/m were obtained, all by chance being just 1.757, and in 1936 I gave3 1.7576240.00026 as the most probable value. It appears now that most of these new "low" values repre- sented preliminary results only, and the final values now available are appreciably higher. In fact Dunnington,4 in connection with his own beautiful work on elm, gave 1.7584±0.0003 as the most probable value. He found, however, that a discrepancy of 0.0016 still existed between the weighted averages of the'spectroscopic and the deflec- tion measurements, and this, although only one-fifth of the 1929 discrepancy, was still, as a result of the greatly increased accuracy of recent work, almost three times the sum of the assigned probable errors. At the present time there are available ten precision values of e/m, six
