6. Notes on the Cultivation of Algae for Class Use, F. L, 
Stevens, of the North Carolina College of Agriculture 
and Mechanic Arts. 
Suggestions were given for the isolation and cultivation of 
algae upon solid medium, consisting of 75 per cent, ager made 
up with Knopf’s solution. This medium solidifying at lower 
than 34 degrees, can be safely used in plating out algae. 
Cultures of several forms were exhibited. 
7. Fusion of Sponge Larvae with formation of composite 
sponges, H. V. Wilson, of the University of North 
Carolina. 
The ciliated larvae of silicious sponges (Stylotella) may 
be made to fuse, thus giving rise to composite sponges. To 
accomplish this result it is only necessary to bring the larvae 
in close contact at the time when the ciliary action is no lon- 
ger locomotary and fixation is about to occur. The compos- 
ite masses representing (in the actual experiments) from two* 
to six larvae complete the metamorphosis.
