THE ELIMINATION OF POTASSIUM IODID IN THE URINE

This work was entirely confined to the study of the urinary elimination of potassium iodid after oral or rectal administration. The patients of the general ward type were given 1 gram of potassium iodid and the urine was subsequently examined to determine the total amount of potassium iodid excreted day after day, until the last traces had disappeared. For comparison, whenever possible, the same patient was given a similar quantity of potassium iodid per rectum (by proctoclysis) and the urine was treated in the same manner as before. It is not the intention of this paper to discuss the action, uses and polytherapy of iodids in medicine. The technic employed for the quantitative analysis was the following: 1.
