Thus it can be established for every concentration, which percentage 
of the bloodcorpuscles lose their haemoglobin in one particular solution, 
whilst they could withstand a solution which was 0.02 °/, stronger. 
If, therefore, we analyse in this manner the values obtained with 
the anaemic animal every day, then we shall find for which percentage 
of the erythrocytes every salt-solution represents the minimum con- 
centration. (See Table C). The 3 series of values obtained, may be 
expressed again in curves (Fig. 3). There are always one or two 
salt-concentrations representing for the greater number of erythrocytes 
the minimum concentration they can bear. On the first day these 
maxima are found at 0.58 °/, and 0.51°/, NaCl, on the second day 
at 0.49°/, NaCl, and on the third day at 0.45°/, and 0.43 °/, NaCl. 
These maxima too move in the direction of the less concentrated 
solutions.

Hence the number of strong blood-corpuscles increases as the 
number of weak ones decreases. This increase on the one hand and
