provided that whilst inserting and removing the pessary she has placed her body in a suitable posture--say, lying on the back with knees drawn up, sitting on bidet, or standing with one foot on a chair, or whatever other position she finds suitable. A doctor's help is needed only when first selecting the right size of pessary. The pessaries are made in ten different sizes, each size being numbered, and the right size can always be obtained on order. No harm may come from wearing the pessary for a day or two, but it is highly desirable as a matter of cleanliness and otherwise to remove the pessary in the morning when performing the sexual toilet. The pessary should, of course, never be worn during the menstrual period. A good rubber pessary should last from three to four months, and it should be tested occasionally by filling it with water to see that there is no hole in it. If it has been fitted shortly after a miscarriage or confinement, refitting is desirable at the end of a few months. But in normal circumstances refitting is not necessary.

These melt rapidly after introduction and provide a pool of antiseptic fluid around mouth of womb.] [Illustration: DIAGRAM 7. COVERED SPIRAL SPRING RUBBER PESSARY. SEEN IN PROFILE. It is understood that this is circular. The thickened rim retains this circular shape by means of enclosed spiral spring when the pessary is in position. To insert conveniently, the thumb and forefinger are placed on opposite sides of rim, and the spring pressed into a long oval shape.]
