Effect of the ingestion of citric or acetic acid on the amount of calcium in the urine was examined by the writer himself. As a result, these acids were found to effect increase of calcium in the urine while the calcium decreased on the concurrent ingestion of dlsodium phosphate than in the case of citric or acetic acid. The changes in the amount of calcium in the urine was assumed to be due to the effect of citric or lactic acid ingestion on metabolism in the human body. The decrease in the amount of calcium in the urine with concurrent ingestion of a phosphate seemd to be of special significance.
