This counteraction is represented in two graphs. The data of the 
first are taken from the literature, in which are recorded a great 
number of widely different and efficient combinations of salts as 
generally accepted circulating fluids. The second illustrates the results 
of experiments purposely performed. In both graphical representations 
‘a well nigh straight curve indicates the ratios in which either the 
potassium-salt or the uranium-salt must be combined wilh the cal- 
cium-salt. Potassium-chloride and uranyl-nitrate also admit of an
