Half a pound of plain, white soap, dissolved in a small quantity of
alcohol, as little as can be used; add a tablespoonful of pulverized
borax. Shave the soap and put it in a small tin basin or cup; place it
on the fire in a dish of boiling water; when melted, add the alcohol,
and remove from the fire; stir in oil of bergamot sufficient to
perfume it.
