 here. The admiration felt for the magnitude and the continuity 

 of his labours is heightened by the fact that his health was 

 always weak and his constitution somewhat frail. His death, 

 which was quite unexpected, took place on July 17th, 191 2, at 

 an age when the world had still great things to expect from him 

 The Denueres Pe/'sees, a posthumous collection of essays on his 

 favourite topics, gives a pathetic indication that the evolution of 

 his own thoughts was still in progress. H. L. 



Professor Eduard Stkasburgek, who died at Bonn on 

 May 19th, 1912, was born at Warsaw in 1844. By his death 

 Botan)- lost one who had played a large part in the construction 

 of the science in its modern form. The dates of his numerous 

 publications range from 1S67 to 191 1. He thus came into the 

 science after the significance of the theory of evolution had been 

 realised, and after the main comparisons of the various groups 

 of the vegetable kingdom had been correctly established by 

 earlier workers. The details of cell-structure were, however, 

 only beginning to be known, and cytology, as we now under- 

 stand it, was not even sketched out. Although Strasburger's 

 work was by no means limited to this field, the cytological 

 interest runs through most of it, and the pioneer part he took in 

 the investigation of cell-structure and nuclear division would 

 alone establish his great distinction as a botanist. 



Strasburger's early work on the details of fertilisation in 

 Bryophytes, Ferns, and Conifers led to his comprehensive inves- 

 tigations into the morphology of Gymnosperms, with special 

 reference to the details of reproduction. To this period we owe 

 " Die Coniferen und Gnetaceen" (1872) and '• Die Angiosperraen 

 und die Gymnospermen " (1S79). In 1875 his classic work 

 " tJber Zellbildung und Zelltheilung,'' which was subsequently 

 published in enlarged second and third editions, appeared. From 

 this period onwards his work was mainly cytological, and most
