V1 11 DESMIbS OF THE UNITED STATES. 



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

 searches in American water-. !". \\'. Harvey, Orono, Maim-, has 

 been active in researches among the Aff/a-. Many other?- might he 

 named who liave 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 prevailed, judging by the nu- 

 merous papers which made their appearance the past few year-. 

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

 added to his previous achievements his contribution to the A/f/n of 

 Hra/il ; his discoveries in the Arctic regions, in Greenland and Spitx- 

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

 by Dr. 8. Berggren in New /ealand and Australia. Dr. Wille, of 

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

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

 care of the Desmids of Hungary. YV. M. Maskell presented three 

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

 heim tells of Bengal plants; Roy & Bisset of Japan gatherings ; YV. 

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

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

 collections in Spain; W. West, gatherings in Yorkshire; J. P. Bis-ct
