In the following observations, the action of normal cells and patient’s cells, 
from a case of acute general peritonitis, was tested in the serum of another 
patient suffering from chronic pulmonary tuberculosis. 
1 vol. of normal washed cells, 
1 ,, tuberculous serum, 
1 ,,. melanin. 
1 vol. of patient’s washed cells (acute peritonitis), 
1 ,, tuberculous serum, 
1 ,, ~=+melanin. 
This observation, like the three that precede it, shows that the washed 
cells, from a case of acute infection, are more active that normal cells, in 
the serum of a patient suffering from another disease, the index being 1°4. 
In the two following observations, the action of normal washed cells is 
compared with the action of the patient’s washed cells, in the presence 
of melanin, in the patient’s serum, heated at 58° C. for 15 minutes.

In the two following observations, the action of normal washed cells 
is compared with the action of standard-pneumonia cells, in the heated 
serum of two other patients.
