Natural secretions are aqueous; water consists of hydrogen and oxygen; hydrogen is. therefore, a natural element and component of the liquids of the body, the solvent of sub stances absorbed and eliminated. Hydrogen is, therefore, a natural base, and superior above all others for combination with substances designed for assimilation.

Iodine in substance, is caustic and irritant; Iodide of Potassium is a combination of two, irritant substances, Iodine and Potassium. This fact is appreciated by all physicians

Iodide of hydrogen (Hydriodic Acid), is non-irritant, has an acid reaction, and conse quently does not interfere with digestion, is more prompt than Iodide Potassium in action is as palatable as lemon syrup, may be given freely to delicate females and young children and may be continuously used, without intermission, (except in cases where iodism is pro duced) until the morbid state is corrected; it produces no depression, indigestion, e

irritation.

It is indicated whenever Iodine is required for internal use.

By the use of Gardner's Syrup of Hydriodic Acid (first introduced by him, fifteen years ago, to the medical profession), the remarkable efficacy of Iodine in this form has beer fully demonstrated, and it is now largely prescribed in place of Iodide Potassium.

As many unscrupulous druggists are in the habit of substituting other preparations wher¦ Gardner's are ordered in prescriptions, the physician who desires to prescribe this Syrup should specify "Gardner's, no other," and instruct his druggist that he will not tolerate substitution. Write for literature, sent without charge to physicians.
