Abstract
IT is often desirable to deliver pregnant sheep by Caesarean section under epidural or spinal anæsthesia so that the respiratory and cardiovascular functions of the new-born lamb will not be depressed by a general anæsthetic. A single injection of the local anæsthetics at present available is sometimes not enough to provide anæsthesia of sufficient duration for experimental purposes. A new local anæsthetic, 2(2,6 dichlorophenoxy) ethyl dimethylamine hydrobromide (SK and F 90,054)1 has proved to have a substantially longer duration of action.
