5. Examination of a solid substance found in a singular tu- 
mor on the fundus of the uterus. 
For this substance, and an opportunity to examine the 
‘‘ subject,” 1 am indebted to Dr. Cyrus Perkins, of New- 
York, late Professor of Anatomy, &c. in this College. The 
history of the subject is unknown; the abdomen was as 
large as in the fourth or fifth month of pregnancy ; on open- 
ing it the apparently enlarged uterus was resting above the 
brim of the pelvis ; on cutting into the tumor, it was found 
to be fleshy and filled with spicule of a hard bony sub- 
stance ; the tumor was covered with the peritoneum; the 
uterus on examination was found of its usual size, and the 
tumor adhering to its fundus. The hard bony matter was 
found, by the usual methods, to consist of 
Animal matter - - - 33.75 
Phosphate of Lime - - 66.25 
100.00 
Did this singular tumor and osseous matter arise from an 
extra-uterine conception?
