 obtained from putrefying horseflesh, but is verv 

 different in its properties, being strongly alkaline, 



I while the latter base possesses a slightly acid reaction, 

 and the physiologic effects of each are also different. 

 Typhotoxin induces lethargy, paralysis, and death 

 without convulsions, while the unnamed base produces 

 strongly marked convulsive symptoms. After death 

 from typhotoxin the heart is found to be contracted in 

 systole. See Ftomains, Table of.
