In assuring you of my admiration, both intellectual and moral, I am, in friend- ship, Jean Perrin Professor of Physical Chemistry, Sorbonne, Paris I am sending you these two publications. Please excuse the scribblings found on the second I did not have any others left. 97. To Hedwig Born [Berlin,] Sunday.
