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

NOTE.--The method of "self-control" is not referred to here, because one
marital relationship per annum might lead to an annual child. In the
matter of limitation of offspring, therefore, "self-control" has no value.

MEDICAL SUPPLIES.

_Rubber Pessaries._--Medical practitioners can obtain sets of occlusive
rubber pessaries from Messrs. E. Lambert & Son, of 60, Queen's Road,
Dalston, E.8. This firm has been manufacturing such articles in England
since 1888, and now makes them in a wide range of sizes, and of special
shape where required.

_Bidets and Syringes._--Syringes are easily procurable, but bidets in
England at present are sometimes difficult to obtain. Good strong enamel
bidets can be obtained from Messrs. E. Lambert & Son, of 60, Queen's Road,
E.8., and they also keep the contraceptive suppositories made by Mr.
Harman Freese in accordance with medical directions mentioned in Foreword.

_Soluble Suppositories (for women)._--These are now being manufactured by
Mr. Harman Freese, of Freese & Moon, 59, Bermondsey Street, S.E.1, from
whom they can be obtained. These suppositories are disinfective as well as
contraceptive, but they are at present sold for the ordinary purposes of
birth-control.

_Sanitary Tubes (for men)._--These tubes are also manufactured by Mr.
Harman Freese, of Freese & Moon, 59, Bermondsey Street, S.E.1, in
accordance with medical directions mentioned in Foreword. It is quite
possible to manufacture an ointment which, if properly used, would be a
preventive of all forms of venereal disease. The sale of such an ointment
is authorised by the State Health Department of Pennsylvania.

_Information_ as to the medical prevention of venereal disease may be
obtained from the Hon. Sec., Society for the Prevention of Venereal
Diseases, 143, Harley Street, W.1. Information regarding birth-control
has been made available to adults in England for the last half-century by
Dr. Drysdale, Sen., and his family and supporters, through the Malthusian
League, whose present address is 124, Victoria Street, London, S.W.1.,
and these pioneers have made a most self-sacrificing effort for the
benefit of poor women by establishing a welfare centre at 153a, East
Street, Walworth, London, S.E.17, where free advice is given in
birth-control
