and one more reliable, is that of touching every pustule, or poc, on the face or bosom with a camel-hair pencil dipped in a weak solution of lunar caustic (_nitrate of silver_), made in the proportion of two grains of nitrate of silver to one ounce of distilled water. The time for application is about the seventh day, while each pustule is filled with a limpid fluid, or before suppuration takes place, the lotion arresting that action, and by preventing the formation of matter, saving the skin from being pitted; a result that follows from the conversion of the adipose tissue into pus.
