The realdifficulty in embryotomy is the contraction of the uterus. Where thenthe blunt hook cannot pass, the same will hold true of other simplest method is that of Braiin, but it requires an amount of forcewhich may be dangerous to the mother. The same does not hold trueof Duboiss scissors. We should then prefer them, resorting to Pa jots. Fig. 181.—Pierre Thomas Embryotome.—.4, Posterior blade.

In every case where we have been called upon todetruncate or eviscerate, Duboiss scissors have answered us well. Wehave had six successes in seven cases. After decapitation the body of the foetus readily follows on traction onthe arm. The head may give us trouble. In case it resists our gentleefforts with the hand, or cephalotribe, we may try a blunt hookinserted into the mouth. 284 A TREATISE OX OBSTETRICS. Embryotomy is always a grave operation. The mortality rate is, there-fore, high, even where practised with the greatest possible care and ex-pertness. Such are the operations which may be practised on the foetus. Maythey be compared one wi
