inhibit the hydrolysis of amygdahn by emulsin. Since serum is a strong 

 buffering medium the inhibitory effect due to a possible decrease in 

 H+ concentration appears to have been eliminated in these compara- 

 tive studies.

Bayliss (1912) immunized four rabbits intraperitoneally Vi^ith emul- 

 sin in toluene water injecting 5 ml. of a 5 per cent emulsin solution 

 at intervals of six days for seven or eight weeks. Eight days after the 

 last injection the rabbits were bled and the sera were collected. The
