Since hypodermic and submucous injections of paraffin were firstintroduced by Gersuny in 1900, the method has been applied to a variety of conditions with most gratifying results. Solid and liquid paraffins are mixed in such proportions that the mixture has a melting point of from 96.8 to 104 F. This is sterilized by boiling, drawn into a sterilized syringe while liquid and injected after cooling partially, the material passing from the needle as a semi-solid thread. If paraffins of a lower melting point are used they do not become firm enough, and if those which require a higher temperature to melt are employed, the heat needed to keep the paraffin soft enough to allow it to be injected may do harm. Sterile paraffin is devoid of any toxic properties and when injected hypodermically produces no reaction. In places where the paraffin is not subjected to pressure, it remains where injected,
