 feeding-times. Bronchitis and bronchial catarrh — ■ 

 iodol and senega. To foul wounds, ulcers, sores, etc.

 introduced into fistulee, the rectum, and genito-urin- 

 ary organs as antiseptics. To open joints, one of the 

 best applications is equal parts of iodoform and pow- 

 dered alum . Diabetes insipidus has been successfully 

 treated with both iodoform and iodol— preferably the 

 latter.
