Transactions . ntal contused wound 3 cm. long abovethe outer half of the eyebrow, and partially absorbed extravasa-tion of blood beneath the skin of the brow, temple, and lids,and also beneath the conjunctiva, chieily on the temporal was no blood in the anterior chamber. The pupil wasirregularly dilated and immovable. Its long axis at an inclina-tion of about 165 degrees, measured 7 mm. and the short axis4^ mm. There was a notch in its temporal border, a littleabove the horizontal meridian, which extended to within 3 the periphery of the iris. When examined by focal illumina-tion the apex of this notch was seen to be a ragged anglecrossed by a network of fine thread-like fibres which seemed tobe a part of the iris stroma which had resisted the force thatruptured the muscle and vessels. There were also numerousminute serrations in the margin of the pupil, noticeable only bythe use of a lens. By means of transmitted light with themirror and a strong convex eye piece a number of narrow. r .-) Harlan : Rupture of the Iris. 641 radiating streaks of red fundus reflex could be seen on the sur-face of the iris, those on the inner and nasal portion beingsituated about midway between the free and the attachedmargins of the iris and those above being near the edge of thenotch. Thirteen of these minute ruptures could be counted,but they could not all be seen at the same time as they couldbe detiscted only when brought into proper relation with thesource of light and the eye of the observer. This picture(Fig. i) shows the notched and serrated pupil and the smallradial slits in the iris as they appeared when examined with themirror and a 4 D. lens. Careful inspection with focal illumina-tion showed a slight peripheral trembling of the iris. As therewas no other indication of disturbance of the lens, it seemspossible that this may have been due to the shattered andrelaxed condition of the membrane rather than to loss of sup-port. The fundus was normal, and vision,
