irrigation can be so arranged as to let the lotion flow into the vagina
faster than it can flow out--hence distension of walls of vagina and
thorough cleansing. But the arrangement of a runaway for outflowing lotion
is inconvenient in most households.

5. _Quinine Pessaries, etc._--By themselves these are unreliable, no
matter what the makers claim on the label. There is usually not enough
quinine in them; or if there is enough, it proves irritating.

6. _Solid-Ring Check Pessary._--These are reliable only when carefully
adjusted over the mouth of the womb, and many women find it very difficult
to adjust this kind of pessary correctly; hence numbers of failures.

7. _Vaseline and Soap-and-Water._--Using vaseline beforehand, and
urinating and using soap-and-water _immediately_ after _each_ connection,
is a fairly safe way of avoiding conception and infection. But the
vaseline needs to be inserted fairly high up--if possible over the mouth
of the womb, and the subsequent washing needs to be very thoroughly done
(internally and externally). This method is commonly used by Continental
women, but it is not entirely reliable by itself.

8. _Gold Spring Check Pessary._--This is an instrument, the arms of which
spread out inside the womb, and the gold spring keeps the mouth of the
womb open, thus facilitating infection and conception. It is claimed as a
"preventive"; it is really an abortifacient, and cannot be too strongly
condemned, as causing septic miscarriage (authentic records of this are
available). A woman can neither insert nor remove this instrument herself.

9. _Safe Period._--It is often supposed that sexual intercourse midway
between the menses is unlikely to result in pregnancy. There is no such
