This was also the opinion ofKamsbotham, from whose work the following plates are taken. Hehad never seen a true hour-glass constriction, such as the right handdrawing. Miller claims to have met with the condition on several oc-casions.—Ed.] Encystment of the placenta, however, although morerarely, unquestionably takes place in a portion only of the body ofthe uterus (Fig. 138).
