Dr. Brett then exhibited a peach, which was coloured 

 throughout with chromate of lead. The bloom was given 

 with vermilion, the apple-green was a mixture of chromate 

 of lead and ultramarine blue. In a figure of Paul Pi;y, the 

 collar of the coat was coloured Avith red lead, the coat itself 

 with Prussian blue ; the waistcoat with arsenite of copper ; 

 and the hat with chromate of lead. Dr. Brett thought that 

 much injury was done to the health of children by these 

 poisonous substances, particularly as the coloured confec- 

 tionary was more attractive to the eye ; and it was suggested 

 by other gentlemen that he would himself confer a favour 

 on the makers of these articles by showing how the required 

 effects could be produced by innocuous substances.
