is shown at a. In the same fluid (Fig. 9, a) we have 
a great number of minute oval cells, resembling the 
Torula of the Yeast-plant , which are probably the 
spores or sporangia of the Sarcina . The Gonium 
pectorale is represented in Fig. 9, c d, for comparison 
with the Sarcina. The colour of the Gonium is 
always a bright green, and in the fresh state indivi- 
duals may be seen moving rapidly across the field of 
the microscope. As they form the nearest approach 
to the Sarcina , a representation has been given. In 
the vomited matters many other substances are detected 
under the microscope, such as fat, starch, muscular 
fibre, &c. ; but with these we have nothing to do at 
present. 
The probability of the development of the Sarcina
