According to Manson,i^* vulval tumors 396 TROPICAL DISEASES. may weigh from 8 to 10 pounds ( to Kg.), or evenmore. The treatment consists in the surgical removal of thetumor. Elephantiasis oi the Breast, Arm, Scalp and Other Re-gions. Elephantiasis of the breast is very rare. That of thearm is even rarer, and that of the scalp is seldom seen. Otherregions of the body may be affected, but only in the veryrarest instances. The treatment is the same as that indicated for elephan-tiasis of other Fig. 18.—Filaria nocturna. {Da Costa.) Filarial Organisms. As a rule, the filarise can be foundin the blood only during the night hours. However, thereare exceptions to this rule. Bahr,i48 for instance, working inthe Fiji Islands, found the microfilarize as readily during thedaytime as at night. In a fresh-blood specimen the Micro-filaria bancrofti appears as rfiinute, transparent, colorless,snake-like micro-organisms, which do not change their position onthe slide, although they wriggle about in great activity, con-stantly agitating and displacing the cellular elements of theblood (see illustration). In the course of a few hours the move-ment ceases. The microfilariae are long, slender and extremity is abruptly rounded, and the other graduallytapers to a fine point. The filaria is about millimeters(001 in.) in length, and to ( to in.)in diameter; in other words^ approximately the diameter of ELEPHANTIASIS.
