Probably the most interesting passage in her book for the modern time is that with regard to a torn perineum and its repair, even when prolapse of the uterus is a complication. The passage, which may be found readily in De Renzi or in Gurlt, runs: "Certain patients, from the severity of the labour, run into a rupture of the genitalia. In some even the vulva and anus become one foramen, having the same course. As a consequence, prolapse of the uterus occurs, and it becomes indurated. In order to relieve this condition, we apply to the uterus warm wine in which butter has been boiled, and these fomentations are continued until the uterus becomes soft, and then it is gently replaced. After this we sew the tear between the anus and vulva in three or four places with silk thread. The woman should then be placed in bed, with the feet elevated, and must retain that position, even for eating and drinking, and all the necessities of life, for eight or nine days. During this time, also, there must be no bathing, and care must be taken to avoid everything that might cause coughing, and all indigestible materials." There is a passage almost more interesting with regard to prophylaxis of rupture of the perineum. Trotula says: "In order to avoid the aforesaid danger, careful provision should be made, and precautions should be taken during labour after the following fashion: A cloth folded in somewhat oblong shape should be placed on the anus, and during every effort for the expulsion of the child, that should be pressed firmly, in order that there may not be any solution of the continuity of tissue." There are records of other women professors of Salerno, though none of them as famous as Trotula. A lady of the name of Mercuriade is said to have written "On Crises in Pestilent Fever," and as she occupied herself with surgery as well as medicine, there is also a work on "The Cure of Wounds." Rebecca Guarna, who belonged to the old Salernitan family of that name, a member of which in the twelfth century was Romuald, priest, physician, and historian, wrote "On Fevers," "On the Urine," and "On the Embryo." Abella acquired a great reputation with her work "On Black Bile," and curiously enough on "The Nature of Seminal Fluid." From these books it is clear that, while as professors they had charge of the department of women's diseases, they studied all branches of medicine. There are a number of licences preserved in the Archives of Naples in which women are accorded the privilege of practising medicine, and apparently these licences were without limitation as to the scope of practice. The preamble of the licence, however, suggests the eminent suitability of women treating women's diseases. It ran as follows:
