Since its recognition many therapeutic agents have been used in the treatment of the disease, and iodides have held a prominent place among these agents. Little attention has been given to the use of intravenous injections of compound solution of iodine U. S. P., as suggested by Ravaut,4 in the treatment of this and other mycotic
