^'"1 DESMIDS OF THE UMT£I> STATES. 



W. "West and W. B. Turner, of England, in like manner, made re- 

 searehes in American waters. F. W. Harvey, Orono, Maine, ha^ 

 been active in researches among tlie Algce. Many others might be 

 named who have made a beginning. Personally have done very 

 little collecting. The explorations so delightful in the past have 

 become impossible by the advance of years, failing health and con- 

 sequent loss of vigor of body. 



In foreign countries much interest prevaileil, judging by the nu- 

 merous papers which made their appearance the past few years. 

 Dr. Otto Xordstedt, of Lund, Sweden, a veteran in the field, has 

 added to his previous achievements his contribution to the Algae of 

 Brazil ; his discoveries in the Arctic regions, in Greenland and Spitz- 

 bergen and in Bornholm ; he worked up also the collections made 

 by Dr. S. Berggren in New Zealand and Australia. Dr. Wille, of 

 Stockholm, made three contributions to the Desmids of Xorway, of 

 South America and of Nova Zembla. Dr. Schaarschmidt has taken 

 care of the Desmids of Hungary. W. 31. Maskell presented three 

 valuable papers on the Alga (Desmids) of New Zealand. Dr. Lager- 

 heim tells of Bengal plants ; Roy i Bisset of Japan gatherings ; W. 

 Joshua, of Burmah ; Eug. Warming of Central Brazil ; A. W. Ben- 

 nett of North Cornwall and English Lake Districts ; Maria Lewin of 

 collec-tions in Spain; W. West, gatherings in Yorkshire ; J. P. Bisset 

 in Lake Windermere ; John Roy in Scotland, and probably many 

 others not represented in my library.
