1. Small cocci which, near the surface of the gelatine, form 
grayish-white sharply defined spherical colonies, the periphery 
being of a pale yellow color. Under a high power they appear to 
possess a proper movement, and occur in knots of two and four. 
These are probably the carriers of the contagion. 
2. Large cocci which form pale green spherical colonies with 
rough and indefinite surfaces, and under a high power show only 
slight Brownian movement. These were not always present. 
3. Small cocci in gray, yellow, dark, sharply defined colonies 
with a delicate cloud in the neighborhood, presenting, under a high 
power, groups of two to four, but possessing no separate movement. 
In stained preparations they are not distinguishable from (1), but 
are ineffective for vaccination. Three out of fourteen calves were 
successfully vaccinated with (1). 
PHENOMENA OF THE Division oF THE CELL-NucLEus.—M. L. 
Guignard directs attention to some of the phenomena which ac- 
company the division of the nucleus of the cell, with especial refer- 
ence to the theories of M. Degagny. That botanist teaches that the 
nuclei disappear }rogressively as the equatorial zone becomes col- 
orable. This is denied by M. Guignard, who points out that the 
coloration of the equatorial zone is due not to nuclei, but rather to 
the cystoplasmic granulations, which play an important part-in 
the formation of the cellular plate, and of which M. Degagny 
makes no mention. The figured element must not be confounded 
with the amorphous nuciear fluid; methyl-blue is not a suitable 
substance for differentiating the elements which enter into the con- 
stitution of the nucleus or of the cell.— Royal Mic. Jour.
