308 BOTANICAL GAZETTE [OCTOBER 
The second collection is the Sphagnum collection. Through his syste- 
matic and anatomical work on the Baltic Sphagnacez Russow was known as 
one of the foremost students of the group. He had intended to extend his 
monographic work when interrupted by death. The collection consists of 314 
fascicles, and about ane ae microscopical preparations, with outline 
sketches of the same, especially of the species which have been already worked 
up. In addition there are ss photographic lantern slides of localities of the 
different sphagnums. It is much to be desired that this collection also be 
made generally accessible in some institution. It would be especially valuable 
for America, as it contains the European species, varieties, and forms com- 
pletely and critically determined and worked over; and the exact relation of
