spirit in the founding of the Natural History Society 
of Stromness, in the management of which he took an 
exceedingly active part ; he was president from 1837 
to 1885. It was during his presidency that the 
museum was commenced, and to it he devoted much 
time and energy. To the archeological and geological 
sections of the museum he presented many specimens. 
To-day the collection as a whole is a credit to 
Stromness—being kept clean and bright, and the 
arrangement of the exhibits being systematic and 
easily intelligible. We hope it will some day have a 
full herbarium of Orkney plants, as the museum of 
Thurso has of Caithness plants. Dr. Clouston’s addi- 
tions to the published lists of Low and Neill were 
recorded in his able and interesting account of the 
Orkney Isles in “ Anderson’s Guide to the Highlands 
and Islands of Scotland,’ which, to this day, is inter- 
esting and accurate. In his plant list there are two 
or three of special interest :—Senecio viscosus was 
reported by him to have grown in Harray and Firth. 
This species has not been found recently. He was the 
first, | understand, to add Chara aspera to the list of 
British plants. In his list are also Draba hirta and 
Primula elator, which have not been found for some 
time as far as I know. His special study, however, 
was marine alg. During his day the study of the 
marine algze round Orkney was actively pursued also 
by Dr. Pollexfen, Mr James Cursiter, F.S.A.Scot., Mrs 
Moffat, and her sister, Miss Watt, Skail. Dr Clouston’s 
name will long be held in reverence in Orkney, and 
especially in Sandwick and Stromness, for his self- 
sacrificing devotion to his parochial duties as well
