82 BACTERIAL POISONS. 



a portion of the vomited matter, and the mucous membrane 

 very white and soft. There was not the slightest redness 

 anywhere. The liver and other abdomioal organs seemed 

 normal. 



A bit of the solid portion of this cream was added to 

 some normal milk, which, by the addition of eggs and 

 sugar, was made into a custard. The custard was allowed 

 to stand for three hours in a warm room, after which it 

 was kept in an ice-box until submitted to chemical analysis. 

 In this tyrotoxicon was also found. 



Tyrotoxicon has since been found in some chocolate 

 cream which poisoned persons at Geneva, N. Y., and in 

 lemon cream from Amboy, Ohio. 



ScHEAEER reports the finding of tyrotoxicon in both 

 vanilla and lemon ice-cream which made many sick at 

 Nugent, Iowa.

 frozen Tuesday afternoon, having stood in the freezers

No analysis of this cream was made, but the symptoms

Wblfoed observed several cases of poisoning from 

 custard flavored with lemon. These custards were tested 

 for mineral poisons, with negative results. 



Morrow has put forth the claim that ice-cream poison- 

 ing is solely due to artificially prepared vanillin, which is, 

 according to his statement, used instead of vanilla extract, 

 but the facts stated above concerning poisoning with creams 

 in which other flavors had been used contradict this claim. 

 Moreover, Gibson has shown the utter absurdity of the
