    from having had to carry the lymph of the right leg as well as that normally passing through them, give way; there is then a lymph-scrotum producedj and in the fluid periodically escaping the young of the parasite or its ova may be found. Not having passed through any glands the lymph will be clear and straw-coloured as it is at the radicles. Perhaps the scrotal lymphatics, being strong and well sup- ported by a powerful dartos and thick skin, may not give way; the lymph will then accumulate there, or gravitation may determine it to a leg, or both legs; or all of these parts, as not unfrequently happens, may enlarge. In such a case, there being little or no circulation of lymph, probably the parent will die. If the worm is located in the scrotum much the same effects will ensue. But if she is in a lymphatic trunk of the pelvis or lumbar region, then, should the stasis caused by the ova involve the lymphatics of the kidneys, ureters, or bladder, chyluria may follow. As the parasite in this case is probably betwixt two glands, and as the anastomosis of the vessel in which she lies is guarded in all directions by glands, it may be impossible, if all of these are plugged, for embryos to get into the circulation. Generally, owing to the richness of the anastomosis, the plugging is not complete, and the parent sur- vives ; on the degree of obstruction, therefore, will depend the presence or absence of embryos in the blood. In addition to producing more or less com- plete stasis in a particular region, such an accident among the lumbar or pelvic lymphatics must diminish the number of vessels available for the transmission
