the substance. 
The cells were at first so nearly the size of Bacterium 
incarnatum as to suggest that species, though the color 
as certainly suggested Bacillus ruber. Later slides 
show somewhat larger cells,—some short and thick, 
others long and slender. Spore-bearing filaments are 
also seen. The walls of the little oval cells took the 
staining fluid well, but the interior remained colorless. 
The cells measured about .5-.7 by 1-3. in the earlier 
cultures. 
Bacillus ruber (?). Among my earliest cultures, I ob- 
tained a pink zoogloea with cells corresponding in size 
with those of the species mentioned, but the color was 
so far removed from that described by Frank, that I 
very doubtifully mention it here, particularly as I was 
unable to keep the zoogla@a more than four or five days. 
Dr. Stevenson, in behalf of the Section, gave cordial

cussed by Messrs. Dwight, Cooley and Stevenson.

NEW STARS IN ANDROMEDA AND ORION. 
BY MISS MARY W. WHITNEY. 
I propose this evening to give a few facts about the 
new stars which have appeared in the heavens within 
the last two years, the Vova Andromede and the Nova 
Orionis. As the interest in a new star turns quite as 
muck upon the light it may cast upon the nature and 
classification of earlier phenomena of like character as
