5. (W. Cooley.) A piece of spread adhesive plaster is placed upon a table,

and a piece of card paper having a round hole cut in it the size of the

central portion of the corn is laid upon it; the exposed part is then

softened by holding a piece of heated iron for a second or two near it;

the card paper is then instantly removed, and nitrate of silver, in fine

whole is cold, the loose powder is shaken off, and the plaster is ready

for use. Very cleanly and convenient. Two or three applications seldom
