Twelve days after copulation are required before the ovum is as large as Peters 's and thirteen days before it is as large as Merttens's. When it is recg^lled that Merttens's ovum was scraped out of the uterus twenty-one days after the beginning of the last period we are inclined to believe that sixteen to twenty-one days represents its true age. Peters 's ovum, on the other hand, must be over ^Hhree or four days old"; fifteen is much more nearly its correct age. | Twelve days after copulation are required before the ovum is as large as Peters 's and thirteen days before it is as large as Merttens's.

When it is recg^lled that Merttens's ovum was scraped out of the uterus twenty-one days after the beginning of the last period we are inclined to believe that sixteen to twenty-one days represents its true age.
