Borellus cites an instance, and there are many others, of pregnant women eating excrement with apparent relish.

Tulpius, Sennert, Langius, van Swieten, a Castro, and several others report depraved appetites.

Several writers have seen avidity for human flesh in such females.

Fournier knew a woman with an appetite for the blood of her husband.

She gently cut him while he lay asleep by her side and sucked blood from the wounds--a modern "Succubus." Pare mentions the perverted appetites of pregnant women, and says that they have been known to eat plaster, ashes, dirt, charcoal, flour, salt, spices, to drink pure vinegar, and to indulge in all forms of debauchery.
