riclied when he undertook its superintendence, — whence, 

 indeed, Brongniart derived most of his materials for his 

 " Vegetaux Fossiles." 



As his friend Lesquereux remarks: " The above enumera- 

 tion cannot give an idea of tlie amount of work performed by 

 this celebrated naturalist during a career harassed by the 

 most distressing circumstances. It says nothing of the 

 noble character of the man who, always genial, kind, and 

 obliging to every one who needed his assistance, has left as 

 shicere friends to deplore his loss all those who had inter- 

 course with him." * 



Dr Nils Johann Andersson, Professor of Botany at 

 Stockholm, was elected one of our Foreign Members on 

 December 8, 1870, he having previously enriched the 

 European department of the University Herbarium with 

 many valuable specimens, notably of the Scdices, which were 

 a special study with him, having written the monograph 

 on this family in De Candolle's " Prodromus." Andersson 

 was a botanist by vocation, as well as through love of the 

 science. He prepared himself for his professional career, 

 by university graduation at Lund in 1845 as Doctor of 

 Philosophy, by holding the positions of assistant professor 

 and demonstrator, by travel, whether round the world in 

 the frigate " Eugene " in 1851 to 1853, or afterwards in an 

 extensive European botanical tour, embracing Lapland, 

 Norway, and England. He died on March 27, 1880, at 

 Stockholm, after long suffering, in his sixtieth year.

 Hanstein was also Professor of Botany ; and was enrolled 

 amongst our Foreign and Corresponding Members on 

 January 9, 1873. Vegetable physiologists set a high value 

 on the work of our deceased coadjutor. One capital dis- 

 covery of the three distinct layers in the developing 

 embryo of Capsella bursa pastoris, as well as other Cruci- 

 ferse, quite identical in their further development with the 

 formation of the embryonic membrane in animals, has been
