    than those generally met with in lymph-scrotum, and softer than those usually associated with elephantiasis. One gland in the left groin — the uppermost and outermost — felt slightly softer than the others, and a hypodermic syringe drew off from it a small quantity of perfectly clear lymph. In this lymph I found eleven ova, presumably of filar in sanguinis hominis, and one languid free embryo. The ova were all advanced to the last stage of development; each contained a perfect embryo, which moved about inside the delicate wall in a rotatory fashion, just as I had seen the embryos of filaria immitis of the dog, when they had descended close to the vaginal end of the uterus. The ova were oval, the extremities of the long diameter having a tendency to “point.1’ Their dimensions were ^—in. x T]-y-in. I saw no trace of lash in the embryo. In one slide of blood from the finger, taken at the time the lymph was abstracted from the gland (early in the morning), four filarise were found. Two days afterwards I pierced the same gland and abstracted a small quantity of bloody lymph. In this I found neither ova nor embryos; but following the needle, as it was withdrawn, there escaped a drop or two of bloody lymph, and in this I found thirty-five active and free embryos, but no ova. At the time of this last examination blood from the finger contained twelve embryos to the drop. A similar examination, made two days later, yielded one embryo in the lymph, but no ova. Case XXV. Lymph-scrotum; filar ice in lymph from scrotum, also ova containing coiled-up and active embryos; small number of parasites in the blood : operation.—Tui, male, aged fifty; Tehangtchiu, Khiotau; a farmer. There are some 200 to 300 inhabitants in his village, including several cases of elephantiasis. One, called Bexga, I operated on some years ago, removing a 12-lb. scrotum. When young was careless about the water he drank, taking it indiscriminately from pool, well, or river. When a little over ten years of age had frequent attacks of ague, both quotidian and tertian. His scrotal trouble began at eighteen. He had hydrocele then, and at times inflammation of the K 2
