Warts consist of collections of hypertrophied cutaneous papillae, on loops of veins, arteries and nerves. These loops, frequently, without any apparent cause, take on a disposition to grow, and by extending themselves upward, they carry the scarf-skin along with them, which thickens, and the whole forms the wart.
Corns consist in excrescences confined mostly to the toes and soles of the feet, resulting from wearing tight shoes. They occasionally form on the elbows and knees, or on the extremities of the fingers. When occurring between the toes, they are called soft corns.
Bunions consist of an enlargement, thickening, and inflammation of the mucous bursa at the side of the ball of the great toe. Occasionally the bursa suppurates, and a fistulous opening left after the pus has evacuated.
TREATMENT. -- Corns may be cured by shaving them slowly and applying nitro-muriatic acid or chromic acid ointment. For soft corns acetic acid is better. Warts should be clipped off with the scissors, and chromic acid applied, or any other cauterizing agent will answer. The tincture of thuja is also excellent. Bunions are cured by bathing them frequently in the oil of erigeron.
