    3rd.—Encysted tumours in the orbit. When those tumours, which may originate in any part if the orbit, present themselves externally, they form etween the eyeball and margins of the orbit, a rounded, qual, elastic swelling, more or less distinctly iluctu- fctmg, and yielding to pressure, so as to retire within the rbit. The cyst of the tumour is in somo cases thin and BTOUS, in others thick and fibrous, with cartilaginiform nd even ossiform depositions. The contents may bo ratery [hygroma), like suet [steatoma), like pap {atheroma), v like honey (mcliceris). Hairs, and in one case a tooth, ave been found among the contents of orbital tumours, imilar to what is of more frequent occurrence in ovarian amours. Treatment.—Total extirpation when, from the situation nd connexions of the tumour, it can be eifectedj if not, artial extirpation, in the hope that, by exciting iniiain- lation on tilling tho cavity with chaipic, the remains of le cyst may bo eventually destroyed, or separated and orown off by tho suppuration. In some cases sinrple unctiu'e of the encysted tumour and evacuation of its ontents have been performed with success. 4th.—Hydatidgenous cysts in the orbit. ' Ysts containing hydatids have been met with in tho rbit. They presented the characters of enc}'sted orbital amours. On making an opening into the prominent art of tho tumoiu', fluid was evacuated, followed immo- iately in one case by a large hydatid, in another case, fter two or three days, by half a tea-cupful. The following case of echinococcus-cyst in the orbit, which itely occurred to mo, appoars to lie identical with those uoted by Dr. Mackenzie from Schmidt (Ueber die, Krank- citcn des Thranen-organs, p. 73; Wien, LS03), who ori- dnally described the disease, and called it Glandula icrymal is hyt lato idea. A man, about 30 years of age, was brought from St. 'ancras workhouse to University College Eye Infirmary, nth. the left eye in a state of exophthalmia. Tho dis- rganisation hang great, I decided on first excising the rotruding eyeball from the ocular capsule. Tins bein<«'
