It is probable that no more remark-able series of eggs ever gathered to-gether than these eggs, all that areknown, of these Eagles. The size ofan average egg is about by In 1904, when preparing myCondor paper, I obtained all the in-formation possible as to large eggs,both in this country and abroad, fromall oologists whom I knew to havelarge series of eggs of the species.
