Sir Everard Home on corpora lutea. 6g 
Fig. 3. An external view of the ovarium of a sow, 14 days 
after impregnation. 
Fig. 4. The internal view, in which there are five corpora 
lutea, their appearance becoming very indistinct. 
Fig. 5. The ovarium of a sow five years old, that had in all 
six litters of pigs, and had left off breeding for a year. 
Fig. 6. An internal view of the same, to show that all ves- 
tiges of corpora lutea were nearly removed. 
Since the first part of this Paper was printed, a foetus of 
the size usually met with at the end of the fourth month, 
has been found compleatly inclosed in the ovarium. It is 
evident that the ovum, after impregnation, was retained in 
the cavity of the corpus luteum in the manner explained 
above, since vestiges of the corpus luteum are still visible 
between the chorion and the substance of the ovarium. The 
mother died in consequence of haemorrhage, produced by 
the bursting of a branch of the spermatic artery. An ac- 
count of the case, with drawings of the parts made by Mr. 
Bauer, will be laid before the Society, after the long vaca- 
tion, by Dr. Granville.
