2. Cornelius Judge, æt. 28, comes for slight ophthalmia, and is observed to have a minute opaque dot on the anterior part of the capsule of the right lens just below the centre, and a corresponding, but much fainter speck on the cornea exactly opposite. All else quite healthy. He knows nothing of the specks, as his sight is unaffected by them, and they have not been seen before. They have probably existed from infancy, and been due to the same cause as in the last case.

CASE T.-Examination of an eye after the operation of solution.

The following is an account of the examination of an eye taken from an elderly man, who died in the Middlesex Hospital, in 1846, after a contused and lacerated wound of the scalp, which had caused so much swelling of the lids, that the globe had been invisible during life, but it was understood to have been long a "bad one." The eye was obligingly sent me by my friend Mr. Alexander Shaw.

Globe of natural shape and texture externally. No mark of cicatrix on the external tunics. Iris natural. In the lower part of the pupil was seen an opacity apparently of the capsule, irregular, and somewhat moveable; also a more deepseated, more flocculent, and more moveable opacity, which did not appear through the pupil, except in certain lights. On opening the eye, I found the lens nearly gone. In its place was a cavity continuous with the posterior chamber, the margin of the cavity being formed by the anterior part of the capsule, which had been largely opened, and had rolled up on all sides, retaining in some situations its transparency and other usual characters; while in other parts, especially below, it was obscured by a dense white earthy deposit. This deposit had in connexion with it a remnant of the fibrous tissue of the lens, and even traces of the superficial cells of the lens. Some of the fibres were nearly natural; others were more or less granular and broken. The posterior portion of the capsule remained, forming the bottom of the cavity, and when torn by the knife seemed perfectly natural in transparency and texture. It was also interesting to notice that the suspensory ligament of the lens was still there, and in a healthy state, holding the circumference of the capsule as usual. The ciliary muscle, also, was quite as large as usual. The vitreous humor was somewhat less firm in front than usual, and it contained in the midst of its clear, transparent substance, a number of minute chalky-looking streaks or dots, the streaks being mostly directed from behind forwards, towards the back, and particularly the border, of the capsule of the lens. On examination, these consisted of minute granular particles, of an earthy nature, varying in size from mere points to 1-1500th of an inch.

CASE U.-Dropsy of posterior aqueous chamber, with synechia posterior-bulging of the sclerotica over the ciliary processes.

(For a part of the notes of this case, I am indebted to my friend and former pupil, Mr. GEO. SHEPPARD.)

12th Oct. 1848.-Hannah Jones, æt. 28, a single woman, always enjoyed good health till two years ago, when her eyes became severely inflamed from a cold, caught, as she believes, in moving into a cold and damp house. Leeches and other remedies were employed, but did not relieve the pain (which was very acute), or palliate the symptoms. The sight from the beginning of the attack was very imperfect, and in three months was gone from the right eye, and much impaired in the left. Her mouth was made sore, probably by mercury. At present she feels well, and her appetite is good.

Condition of the eyes.-Jerking oscillations of both towards the left side. Left. Posterior synechia. Capsule and cornea cloudy. Can just distinguish the window bars. Right. The same condition, but also distension of the anterior part of the sclerotica, which, for one-eighth of an inch from the cornea, is slatecoloured, full of dull red vessels, and presents both above and below three or four small dark spots, where staphylomatous bulging of the sclerotica appears to be commencing. The dark points are about as large as pins' heads, and seem to be caused by a distension of the posterior chamber with fluid, bulging between the ciliary processes.

The remedies employed had reference to some external inflammation for which she had applied to the hospital, and which was speedily subdued. The condition of the eyes remained. She suffered from frequent dull pain, and there seemed a disposition for the distension of the right eye to increase. There were some blotches of doubtful character on the face and forehead.-Ung. Ant. P. Tart. temp.; Pil. Hyd. Chl. C. gr. v. o. n.

Nov. 9th.-Right eye. I found by atropine that the border of the pupil was in all probability adherent everywhere to the capsule of the lens, for it showed no inclination to recede. As there was a persistence of the pain, and some tendency to further distension, I made a careful puncture with a grooved needle through one of the small projecting points of the sclerotica above, and drew off several drops of very nearly clear, watery fluid, which became very slightly turbid by heat (it was nearly natural aqueous humor.) The operation gave no pain, and though it occasioned an immediate diminution of tension and fulness of the globe, yet it produced no change whatever in the anterior chamber, showing that there was no communication between the chambers through the pupil. No bad symptom followed this puncture, and she felt rather relieved, the pain being lessened, and even vision improved in a trifling degree on January 4th.

Feb. 1st. Still rather improved; no pain; appearances similar. I repeated he puncture, with the same results. There occurs now, on the entrance of the

needle (what occurred before, but it was not mentioned), an instantaneous injection of the vessels of the sclerotica and conjunctiva with blood, so that they look much congested, or actively inflamed, and two or three large vessels (before invisible) disclose themselves in the cornea.

This woman is still in attendance, and continues to improve a little.

CASE V.-Clot of blood in serum occupying the aqueous chambers, undergoing very slow absorption during twelve months.

23rd Dec. 1847.-Wm. Byron, æt. 48, lost his left eye nineteen years ago, by a wound, for which he was treated at this hospital by the late Mr. Scott. The eye has been left with a transparent cornea, serum in the aqueous chambers, ossific, or earthy matter on the capsule of the lens, and enlargement of the choroidal vessels. There is also an inward squint. A fortnight ago, an effusion of blood took place into the aqueous chambers, with pain, followed by injection of the conjunctiva, and a faint zonular redness of the sclerotica. The blood has trickled from the upper part, and forms a red clot, occupying nearly one half the anterior chamber.-Emp. Lyttæ; Magn. Sulph. 3ss. mane; Lot. Saturn. 6th Jan.-Rather more blood; pain in the eye and orbit, as well as in the head; bowels open.-Rep. Emp. Lyttæ; Soda c. Cinch. gr. x. t. d.

17th.-Better; sharp pain gone except at night.-Rep.

31st.-Better; very little pain. The blood remains unaltered. The coagulum presents a film descending from above, showing the point from which it has trickled, precisely as five weeks ago.

24th Feb.-Free from all bad symptoms. The blood remains precisely as before.

23rd March.-Clot slightly less. Some pain on pressure of the globe, with slight zone.-Emp. Lyttæ.

27th April.-Clot a little smaller, and paler, though still red; eye quiet. 22nd May.-Clot reddish, and semi-transparent in the upper part; pale in the lower part.

26th June.-Clot still faintly coloured at the upper part.

4th Dec. 1848.-There is still a semi-transparent mesh of fibrine at the lower part. The globe has been collapsing, and is now four-grooved by the traction of the recti muscles. The cornea is reduced in size, but still clear. The lens and iris unchanged. No pain or inconvenience.
