Lettering attached to the print is on a separate sheet and reads: "The same parturient with narrow pelvis. Radiograph taken one hour later during labour pains. The position of the head has now considerably altered; the head is between the middle and exit of pelvis. the little fontanel has gone deeper and towards the front. That the head has thus turned on its vertical axis can be recognized from the fact that the nape of the neck is no longer visable, as the latter had already moved somewhat from the side to the front (compare table IV). The little fontanel is visable on the lower edge of the descending branch of the pubis, the large fontanel in the foramen ovale to the left. In the plain of the entrance of the pelvis is the tuber frontale to the left. The apex of the head extends deeper into the pelvis exit than in the foregoing picture. (Half an hour after this photograph was taken the child was born.)
