BIOGRAPHICAL NOTES. 
Tuer following notes seem worth bringing together in print, as 
they are from sources not likely to be consulted by botanists in 
search of biographical information. 
Joun Arkin (1747-1822). 
In R. -: Salisbury’s MS. on Campanulacea, preserved in the 
Department of Botany, is the following note under Aikinia :—‘‘ Our 
beautiful little wild plant, Campanula lianas L., is the pes 
Delile. discovered a 2" species in Egypt; an ave a 8" fro 
Burchell, under which he says, ‘Caules humifusi. Fiore steidti: 
post occasum solis dormiunt corollis clausis.’ I therefore call these 
8 species after my earliest botanical preceptor, the late John Aikin, 
.D., whose accurate knowledge of our indigenous Vegetables renders 
a British Genus peculiarly applicable to him. Formerly in very ex- 
tensive practice, when kept up during the night, he made it a rule 
to go to bed, though for tee so short a time, like this Genus, & 
latterly in a green old age, enjoyed the otium cum dignitate which he 
so well merited, beloved by all who knew him 
JOHAN aie ARESCHOUG eas -1887), 
‘‘ Areschoug . charming Swede, Professor at Lund, came 
ver hen for a saa or so, years back. His ardour was such, that 
ofa seeing a new and promising bramble bush, he would plunge into 
it for specimens, like the Guards charging at Waterloo, and emerge 
eventually streaming with gore from face and hands. He had under- 
taken the light job of investigatilig Rubus in Europe, and was after
