The toxicity of cadmium chloride is shown in Table X._ It is 
most toxic in saccharose and least toxic in peptone. In glucose it 
is more toxic than in starch, but less toxic than in lactose. It is 
more than three times as toxic in saccharose as in glucose. Its 
average limit concentration in the different media is .oo1 molar. 
In saccharose, starch and peptone, cadmium chloride is more 
toxic than cobaltous chloride. In glucose and lactose, on the 
other hand, cobaltous chloride is more toxic than cadmium 
chloride.
