The above facts would seem sufficiently wonderful. There are others, however, of the same nature still more so. In some instances, the product of the second conception, instead of developing independently of the first, has become attached to it, and the phenomenon has been presented of the growth of a child within a child--a fœtus within a fœtus. Such a singular occurrence has been lately recorded in a German journal. A correspondent of the _Dantzic Gazette_ states that on Sunday, February 1, 1869, at Schliewen, near Dirschau, 'a young and blooming shepherd's wife was delivered of a girl, otherwise sound, but having on the lower part of her back, between the hips, a swelling as big as two good-sized fists, through the walls of which a well-developed fœtus may be felt. Its limbs indicate a growth of from five to six months, and its movements are very lively. The father called in the health commissioner, Dr. Preuss, from Dirschau, and begged him to remove the swelling together with the fœtus. The doctor, however, after a careful examination, declared that there was a possibility in this extraordinary case of the child within the swelling coming to fruition. Its existence and active motions were palpable to all present. No physician could be justified in destroying this marvelous being. It ought rather to be protected and cherished. The new-born girl, notwithstanding her strange burden, is of unusual strength and beauty, and takes the breast very cheerfully.' We find something further in regard to this singular birth in the _Weser Zeitung_ of February 20, 1869. It quotes from the _Dantzic Gazette_ some remarks by the health commissioner, Dr. Preuss of Dirschau, in which the doctor declares the facts contained in the report given above to be correct. He was summoned on the 1st of February to the child, and saw the vigorous movements, and felt the members of a fœtus within the swelling, as described. It was evidently a double creation. The case thus far, though rare, is not unique. 'But what is novel, and hitherto perfectly unnoticed in medical literature, is the fact that not only the girl, which has been carried its full term, is alive to-day, but the fœtus within the swelling has also, in the eleven days after birth, further developed, and palpably increased in size. The swelling is now four and a half inches long, three and a half inches wide, and high and pear-shaped; the head lies underneath on the left, the body towards the right.' Further particulars and the latest intelligence we have concerning the progress of this case are to the effect that the child was brought by special request before the Natural History Society of Dantzic, and thence the mother went to Berlin for medical advice.
