Abstract
1. SOLUBILITY OF WHITE LEADS IN HUMAN GASTRIC JUICE.
2. TOXICITY OF WHITE LEADS WHEN FED TO DOGS AND CATS.
The lead carbonate is much more toxic than the lead sulphate. But both salts produce acute lead poisoning when given in quantities of 0.1 gr. per kilo body weight daily.
3. THE INFLUENCE OF MILK.
Toxicity of White Leads When Fed to Dogs and Cats.
The lead carbonate is much more toxic than the lead sulphate. But both salts produce acute lead poisoning when given in quantities of 0.1 gr. per kilo body weight daily.
When milk and gastric juice is mixed in the proportion of 1-1, the hydrochloric acid of the gastric juice is so completely fixed by the milk proteins or neutralized by the carbonates in the milk that the mixture has virtually no solvent action on the lead salts, but when gastric juice is present in excess the lead salts g. into solution in proportion to the excess of the gastric juice When milk is taken into the stomach there occurs, of course, a similar fixation of the hydrochloric acid, and, in addition, the total quantity of gastric juice is diminished owing to the inhibitory action of the fats in the milk on the processes of secretion.
