ALTERATIONS IN STATE OF THE 



The 1-18 per cent, serum albumin used by Schorr shows a 

 minimum in the quantity precipitated by alcohol (Table 45), 

 together with a maximum of viscosity and of conductivity in 

 an alkali concentration of approximately o -05 N. The following 

 tables show this property.

This maximum of albumin ions corresponds with the fact 

 that the increase in viscosity with time also reaches a maximum 

 in this concentration of alkali. The same holds good of the 

 decrease in conductivity of alkali albumin mixtures with lapse 

 of time. Compare, for example, the following table with the 

 preceding one.
