    4. Anaesthesia for bag introduction is usually unnecessary, as shown by the fact that in only 14 per cent. Of private cases was an anesthetic used, or in 16.6 per cent, of all cases including many hospital cases in which the anesthetic was deemed advis- able for clinical purposes. 5. In 37 per cent, of all cases, labor begins at the time of the introduction of the first bag, in 70 per cent, of all cases, labor commences within twelve hours after the insertion of the first bag, while in 88 per cent, of all cases, labor begins within thirty hours after the insertion of the first bag. 6. The average length of time intervening between the inser- tion of the bag and the onset of labor is in primiparse eight hours and twenty-two minutes, in multiparae ten hours and twenty- two minutes, and in all cases, nine hours and forty-one minutes. 7. In all primiparse, the average duration of labor induced by the bag, was twenty-two hours nine minutes. In all multiparae, the average was fifteen hours fifty-two minutes and the average in all cases was eighteen hours two minutes. 8. Forty-nine per cent, of labors induced by the bag terminated normally and 70 per cent, terminated normally or with the low- forceps operation. 9. In 5 per cent, of all cases, the presentation was changed, but in only one case was the outcome affected because of the accident. 10. In 139 cases, the cord presented or prolapsed in six, or 4.3 per cent., but it must be remembered that in sixty-three cases, labor was induced for contracted pelvis, relative dispro- portion or hydramnion, and that therefore the accident under any circumstances was much more likely to occur. 11. The morbidity in private work is practically nil, and in hospital work very slight. 12. The foetal mortality in private work was about 5 per cent., in hospital work 11 per cent. This can be explained partly by the fact that private patients receive naturally more individual attention, and the results necessarily are correspondingly better. 13. The maternal mortality from the use of the bag is nil. 144 West Fifty-eighth Street.
