Notwithstanding the high authority of the Count de

 fame time to vindicate the teftimony of fo celebrated an anato- 

 mift as Mr. Littre, by wiping off the afperfion thrown on his 

 veracity, from an injudicious zeal to fupport a particular theory. 

 Inftances of foetufes growing in different parts of the cavity of 

 the abdomen are almoft innumerable, but it is by no means fo

 ftriking example of this kind, and affords feveral particulars equal- 

 ly curious and interefting ; but previous to any hiftory of this 

 cafe, which has come under my own infpedion, I fhall take the 

 liberty of ftating, in as few words as poffible, the moft remarkable 

 inftances of the fame fort which have been related by fuch authors 

 as I have had an opportunity of examining. 



The firft which I have found on record is one related in the 

 Hiftory of the ancient Academy of Sciences, (Tom. ii. page 91)
