A treatise on the science and practice of midwifery . t out of over 105,000 deliveries it was metwith--once in 240 cases, and Scanzoni once in 251. Its frequencyvaries much under different circumstances, and in different find from Churchills figures a remarkable difference in the pro-portional number of cases observed in France, England, and Germany,viz., 1 in 116J, 1 in 207J, and 1 in 156, respectively. Great as isthe proportion referred to Germany in these figures, it has beenfound to be exceeded in special districts. Thus Engelman records 1case out of 91 labors in the Lying-in Hospital at Berlin, and Michaelis1 in 90 in that of Kiel. These remarkable differences are at firstsight not easy to account for. Dr. Simpson suggests, with consider-able show of probability, that the difference in frequency in England, 320 LABOR. France, and Germany, may depend on the varying positions in whichlying-in women are placed during labor in each country. In France,where, although the patient is laid on her back, the pelvis is kept Fig. Prolapse of the Umbilical Cord. elevated, the complication occurs least frequently; in England, whereshe lies on her side, more often ; and in Germany, where she isplaced on her back with her shoulders raised, most often. Thespecial frequency of prolapsed funis in certain districts, as in Kiel, issupposed by Engelman1 to depend on the prevalence of rickets, andconsequently of deformed pelvis, which we shall presently see isprobably one of the most frequent and important causes of theaccident. Prognosis.—With regard to the danger attending prolapsed funis,as far as the mother is concerned, it may be said to be altogetherunimportant; but the universal experience of obstetricians points tothe great risk to which the child is subjected. Scanzoni calculatesthat 45 per cent, only of the children were saved ; Churchill estimatedthe number at 47 per cent.; thus, under the most favorable circum-stances, this complication leads to the deat
