CAZENETJVE AND LEPINE. 



Cazeneuve and Lupine (Bull, de I'acad. de medicine, April 27, 1886, 

 p. 648) says: 



We have arrived at the following conclusions: 



1. The nitro derivatives are especially poisonous (dinitronaphthol being comparable 

 with picric acid), but the sulphonated product is harmless. 



2. Safranin and Methylene Blue are harmful, producing gastric intestinal dis- 

 turbances, being violent poisons. 



3. The following coloring matters are tolerated by man, whether well or affected 

 with Bright 's disease; similarly, too, animals (dogs, guinea pigs) without any noticeable 

 disturbances and at rather high doses: 



1. Fa 



2. Roccellin 



3. Bordeaux 



4. Purple . . 



Among the nontoxic sulphonated colors we have been able to make out the following 

 list or classification, based upon their power of producing disturbances, proceeding 

 from the least inert to the most inert:
