ZOOLOGY AND BOTANY, MICROSCOPY, ETC. 205 



')84 algas, making a total of 5092 plants. Many of the species are merely 

 enumerated, being already known, but descriptions are also included of 

 360 new species of Cryptogams Taigas and fungi). The original drawings 

 for this work, executed in lead pencil and coloured, on bits of Bristol 

 board, are preserved in the Laboratoire de Cryptogamie d'Ecole de Phar- 

 macie, and their general herbarium is said to be preserved at the Biblio- 

 theque at Quimper. The list of their joint publications, mostly on algae, 

 amount to a total of twenty-six. 



M. H. Foslie.* — CI. B. De Toni writes a short obituary notice of 

 Michael H. Foslie, curator of the Botanical section of the Museum at 

 Trondhjem. He was born at Borge (Lofoten) on October 21, 1855, 

 and in 1885 he was elected Conservator of the Museum at Tromso. In 

 1892 he was appointed curator at Trondhjem, a position which he held 

 at the time of his death. His first contributions to algology were on the 

 subject of Arctic marine algae and of Laminaria, published in 1881 and 

 1883 respectively. The marine algas of Norway then occupied his atten- 

 tion, and he wrote a paper on the Norwegian forms of Ceramium as well 

 as other contributions to the marine flora of his native land. But the 

 greatest work of his life was his study of the Corallinaceae, on which 

 subject he knew more than any living botanist. He wrote a large 

 number of papers oil the subject, and but for his untimely death would 

 have written a great work on the system of the group. De Toni had 

 hoped that Foslie would elaborate that part of the Sylloge Algarum, but 

 Foslie refused, saying that he had yet more to examine and study before 

 he would be ready to lay down finally his views. He was ever ready to 

 help other botanists, and his loss will be sadly felt throughout the 

 botanical world. A list is given of his published writings, which 

 number sixty-eight.
