_Gutta Percha made soluble_ (Vol. ix., p. 350.).--E. B. can procure at any
chemist's establishment a solution of gutta percha in chloroform, which may
answer the purpose required by him. It is used by medical men as a dressing
for abrasion in the skin of bed-ridden persons, and is applied with a
camel's-hair brush. It hardens on being applied, and produces an artificial
skin, which saves the patient from farther suffering in the place to which
it has been applied.
