    A CASE OF EPIBULBAR ECHINOCOCCUS, WITH A REVIEW OF THE LITERATURE ON ECHINOCOCCUS CYSTS OF THE ORBIT. By Dr. J. E. WEEKS, New York. ASES of echinococcus1 cysts in the orbit are of such) rare occurrence (none having been reported in this country), that their clinical histories are of value as an assistance in the diagnosis of cystic tumors of the orbit, and in the prognosis and treatment of echinococcus cysts that occur in this region. For these reasons I have thought it best to report somewhat in full the following case of epi- bulbar echinococcus, and also to append a short review of all the authentic cases that I have been able to find reported in English and other literature, together with a few remarks. To the report of cases compiled by M. Dieu, Paris (Rec. d.'Ophthal., 1883 and 1884), I have added six others, five of which were reported subsequent to the appearance of his article. When possible the original articles have been consulted. M. G., age twenty-two years. Austrian Jew. Tailor. Has been in the United States five years. Observes the precepts of the orthodox Jews in regard to his diet. Has no pet dog, nor is there 1 Echinococcus hominis. A small cestoid helminth, about J inch long, which inhabits the intestinal canal of the dog, wolf, and cat. The mature terminal link (proglottis) contains about 5,000 ova ; each ovum contains an embryo (proscolix). On entering the stomach of the host the embryo is liber- ated from the ovum by the action of the gastric juice, and bores its way through the stomachic or intestinal walls, and by the blood-vessels or lymph-channels finds its way into some solid organ, where it develops into a cyst (scolex). From the internal germinal wall of the scolex, or mother cyst, daughter cysts are formed.—(Cobbold on Entozoa.) Reprinted from the Archives of Ophthalmology, Yol. xviii., No. 1, 1889.
