Seeing that glucose cannot enter the blood-corpuscles, no ions can 
leave them. A solution leaving intact the osmotic equilibrium does 
not modify the capacity of resistance. Hence the removal of the 
serum by washing the blood-corpuscles need not alter the capacity 
of resistance. 
The serum contains, therefore, no substances which impede haemolysis.

TABLE D. When the blood has been washed with 0.9 pCt. NaCl-solution, the same 
NaCl-concentration effects more haemolysis than it does in blood which 
has not been washed. 
Blood, washed with a 4 pCt. glucose-solution has mo decreased capacity 
of resistance.
