1. LEWIN (Lehrbuch der Toxikologie, 1897, p. 281}: Rosolic Acid is positively non- 

 poisonous. Small animals can take 1 gram and more of it. In Austria it is 

 prohibited for use in coloring foods. Corallins, or red (Paeonin) or yellow 

 colors, consisting of Aurin and Rosolic Acid were regarded as poisonous 

 because in experiments on man and animals illness occurred, but are said to 

 be poisonous only in the presence of arsenic, phenol, or anilin. These sub 

 stances are prohibited in the coloring of food.

SANTORI (Moleschott's Untersuchungen, 1895, v. 15, p. 47}: A dog weighing 5,250 

 grams received 10.5 grams dye in 22 days, which amounts to 45 milligrams 

 per kilo per day or 32 grains per 100 pounds per day. After receiving 1.5 

 grams the animal suffered copious continuous salivation, anemia, and emacia- 

 tion and occasional vomiting. The urine's color did not change; the feces 

 became blue; temperature slightly above and below normal; although highly 

 emaciated (loss in weight was 1,750 grams or 33 per cent) the animal retained 

 its appetite; animal died on the morning of the 23d day. The autopsy showed 

 oesophagus, stomach, and intestines colored deep blue and filled with a green- 

 ish scum, extended and strong catarrh of the stomach and intestines; kidneys 

 and liver contained very little blood. Conclusion: Poisonous. 

 (NOTE: It is uncertain which of these two dyes Santori used.)
