PHYSIOLOGICAL ACTION OF COAL-TAR DYES. 

 SUMMARY OF SYMPTOMS. 



A rough summary of the symptoms noted or positively deter- 

 mined to be absent, the number of the deaths produced, and the 

 number of cases in which nothing abnormal was noticed may serve 

 as a convenient guide in considering the detailed statements herein- 

 after given relative to all the symptoms, clinical data, legislative and 

 other publications, or permissions. 



In the following tables are brought together most, if not all, of the 

 recorded observations with respect to the humans and other animals 

 upon which the physiological action of coal-tar dyes has been studied 

 as well as the results of autopsies when recorded. The columns 

 headed " Unfavorable," "Favorable," and " Contradictory " have the 

 same significance as in the preceding table; italicized numbers 

 are those of the permitted colors of Food Inspection Decision No. 76. 

 Asterisked numbers indicate that the dye was administered 

 hypodermically.
