I have found an iodized spray or inhalation often useful in these maladies. Dr. W. Curran gives a good formula, containing 4 gr. each of iodine and iodide of potassium in 1/2 oz. alcohol and 4 oz. water. Of this one to four teaspoonfuls may be added to a pint of boiling vinegar or water, and the vapor inhaled every two hours for five to ten minutes.

Menzel has injected a few drops of tinct. iodi into the soft palate and tonsils in diphtheria, and apparently with success (Medical Times, ii., 1873).
