His second case failed, but in a third he was
successful by the same medication with a woman who had before
borne a dead child. In a fourth case of unsuccessful pregnancy
for three consecutive births he was successful. His fifth case
was extraordinary: It was that of a woman in her tenth pregnancy,
who, with one exception, had always borne a dead child at the
seventh or eighth month. The one exception lived a few hours
only. Under this treatment he was successful in carrying the
woman safely past her time for miscarriage, and had every
indication for a normal birth at the time of report. Thornburn
believes that the administration of a tonic like strychnin is of
benefit to a fetus which, by its feeble heart-beats and
movements, is thought to be unhealthy. Porak has recently
investigated the passage of substances foreign to the organism
through the placenta, and offers an excellent paper on this
subject, which is quoted in brief in a contemporary number of
Teratologia.
In this important paper, Porak, after giving some historical
notes, describes a long series of experiments performed on the
guinea-pig in order to investigate the passage of arsenic,
copper, lead, mercury, phosphorus, alizarin, atropin, and eserin
through the placenta.
