The mechanism of labor in the left trans-verse, and in the right anterior, and right transversesacro-iliac positions, is absolutely the same as that just described for the leftanterior one; and again, the mechanism of the left posterior is an exact coun-terpart of that of the right posterior sacro-iliac § 4. Prognosis* Breech presentations are not, usually, much more dangerous than those ofthe head; still, in order to arrive at an intelligent prognosis, the labor shouldbe studied in reference to its effect upon the mother and upon the child respect-ively. Though, from the manner of its expulsion alone, the life of the child isseriously endangered, the parturition is certainly less exhausting and less painfulfor the Delivery of the head in thesacro-posterior positions. MECHANISM OF LABOR. 457 1. As regards the Mother.—As a whole, the labor is somewhat longer in breechpresentations; though, fortunately, the delay is experienced almost exclusivelyduring the first stage, and is the cause of but little additional suffering to themother. The slowness of the process of dilatation is readily explained by theconditions which have been already pointed out. Before the membranes areruptured, the presenting part, having neither the form, roundness, nor regularityof the top of the head, cannot adapt itself to the regular concavity of the inferiorsegment of the uterus, and being separated from the neck by a considerableamount of amniotic fluid, is therefore incapable of hastening its the* membranes happen to ru
