NOTES ON VAUCHERIA. 
The structure and development of Vaucheria has been so often 
and so well studied and illustrated that the observation of any 
new features is quite unexpected, and will probably encounter some 
opposition, or at least excite some doi\bt. One of the generally 
accepted conclusions is, that the threads of Vaucheria are con- 
tinuous throughout their length, only presenting septa at the time 
of reproduction when the short branchlets are isolated for that 
purpose. At all events, successive septation of the main filament 
does not appear to have been recognised by any one who has 
■written upon this family. Of its development it is stated that 
“ the lower part of the germ cell grows out into a branched, pale- 
coloured root, and the upper part is elongated in a still more con- 
siderable degree into a stem-like filament, which grows on and on 
by apical development until its growth is finally arrested by fruc-
