429 grammes. Four days after the injection the animal was killed and 

 estimation made of the antitryptic values of the serum. The estimations 

 were made in duplicate. Temperature, 18° C. throughout. Quantities as

These results may be expressed in the form of a curve (p. 542), from which 

 it will be seen that in this case the effect of multiple injections of water was 

 to give rise to a high antitryptic value in the serum of the injected animal, 

 represented at the maximum point of divergence by approximately six seconds.
