nuary 6, 1669, by Benoit Vassal, surgeon, on opening the body of a woman 

 of 32 years of age, of a sanguine constitution, and a masculine port. These 

 two matrixes were so well disposed by an extraordinary contrivance of nature, 

 that the true one had conceived eleven several times, viz. 7 males and 4 fe- 

 males, all born at the full time, and all perfectly well formed ; but they were 

 at last followed by a brother, yet a foetus, that was conceived in an adjunct 

 uterus, in a place so little capable of distension, that seeking enlargement after 

 it had caused to the mother for two months and a half grievous symptoms, 

 did at last, being of the age of about three or four months, break prison, and 

 found its grave in that of its mother, by a very great effusion of blood in the 

 whole capacity of her abdomen ; which cast the mother into such violent con- 

 vulsive motions for three days together, that she died of them. Whereupon 

 the above mentioned author, after (having embalmed the parts) he had made 

 for a whole month together the particular dissection thereof at his house,, before 

 all the most curious and knowing physicians, surgeons, apothecaries, mid- 

 wives, and other searchers of nature, that are in Paris, thought good to pre- 

 serve the history thereof, by committing it and the figure of the parts spoken 

 of, to the press, together with a table for better explanation ; which we think 

 fit here to annex in Latin :
