Abstract
1. A quantitative method is described for comparing the value of different calcium preparations by the estimation of their relative absorbability.
2. Application of this method showed that the most readily absorbed calcium salt is the chloride. The chlorate has about nine-tenths of the value of the chloride, and the lactate about seven-tenths. The gluconate shows very poor absorbability and a mixture of olete and levulinate was little better.
3. Addition of sodium lactate to calcium lactate, in equimolecular proportions, increased its absorbability to nearly that of the chlorate.
4. Addition of saponin to calcium chlorate did not increase its absorbability.
