In ' Nature ' for July 1879 an inte- resting paper ...appeared, giving an account of the researches of Messrs. Strasburger and Elfving at Jena. They treated pollen grains with osmic acid so as to render the contents more visible, and then they grew them arti flcially in sugar solutions. In a number of the cases observed there seemed to be a breaking up into two or three cells previous to the emission of K -Pollen of Tulip, A, Flowering Rush, c.
