In the second term below "g" is added in pencil. [125] In cgs units P = (76)(13.596)g. In the following calculations, Einstein attempted (unsuccessfully) to move the decimal point, as may be seen in Illustration 38. [126] Should be "Einheit." Einstein trans- posed the "6" and "9" in the sequence "13596."
