Thus fairly accurate results willbe obtained and sufficient amount will be allowed for the moulding.* 4. Manual Engagement of the Head.—Miillers Method (Fig. 226).—Therelations which exist between the head and pelvis may often be determinedby various manual procedures. The so-called method of Miiller has beenbrought into regular and systematic use by prominent obstetricians of Paris, •?-mHI^.

According toBudin, it is sufficient to make an attempt to engage the head in the pelvis, bypressure exerted through the abdominal wall, as in Hofmeiers method forsecuring the engagement of the head during labor. (See Labor.) After thebladder and rectum have been emptied, the accoucheur places a hand oneach side of the hypogastrium (Fig. 227), the head being in relation with theinlet. Pressure is then made in the axis of the superior strait, so that the headis forced into the pelvic cavity. If this engagement can be brought about, *W. S. Stone, Antepartum Measurement of the Fetal Head, N. Y. MedicalRecord, November 4, 1905, p. 725. 184 PHYSIOLOGICAL PREGNANCY. it is evident that labor should be normal.
