The local anaesthetics best adapted for this class of cases are weak solutionsof cocainC; of stovaine, or of beta eucaine lactate, with the preference decidedlyin favor of a solution of cocaine in the strength of from one-quarter to one-halfof one per cent. Sterile water injections for purposes of local anaesthesia havealso been highly recommended by Dr. Gant, in whose hands they seem to have.

We prefer the cocainefreshly made, because it is always reliable. The needle is introduced in themedian line about half an inch back of the posterior commissure of the anusand a drop or two of the solution is injected into the subcutaneous tissues,after which the right index finger is introduced into the rectum and hookedaround the internal sphincter, thus dragging it down into ai)position wit
