Treatment.—Treatment consists in making incisions into the swellings and syringing them out with 2 per cent compound cresol solution. The cavities may then be packed with cotton, soaked in 5 per cent zinc-chlorid solution. The swollen lymphatics may also be bathed or covered with cloths wrung out in this solution.
