The mode of deliverydescribed by Meigs is generally supposed to be the only possible wayin which such a child can be born without perforation or decapitation ;but the case above given, which is extremely rare, if not unique, showsthat if the other be the rule, it has at least, like many other rules,exceptions. In that class of cases in which there is one head and a double condi-tion of the lower parts of the body (Janiceps), the difficulty is not likelyto be so great, as it is much more conceivable that two pelves could besufficiently pressed together during their descent as to admit of their Fig. 195.
