harmful, and cells so treated do not haemolyse more rapidly 

 than normal cells when suspended in • 16 M-NaCl. The loss of 

 components is, however, accompanied by a loss of volume.

Fig. 5. The haemolysis of red cells in the presence of 

 alumina at temperatures between 40° and —5°. Cells 

 suspended in 16 M-NaCl were exposed to 2 g. of 

 alumina per ml. of cells for 15 min. For temperatures 

 below 0°, 2 m glycerol was included in the suspending 

 medium to prevent freezing. Where glycerol was used 

 the experiment is indicated ( X ), otherwise (£). The 

 results are expressed as the log. rate of haemolysis and 

 the reciprocal of the absolute temperature. 



This could result, for example, from changes in the internal 

 composition of the cell due to alterations of its permeability.
