AN EGG WITHIN AN EGG.

A few years since, M. Seguin submitted to the Academy of Sciences at Paris, a hen's egg of extraordinary size, in which was a second egg. Its dimensions were eighty-eight millimetres by fifty-nine, or nearly three inches and a half by two and a quarter. More recently, in 1855, there appeared in an English scientific journal, an account of a similar oological curiosity, produced in Scotland, in the case of a turkey's egg.
