Text Appearing Before Image:
tive-tissue corpuscles ofnormal size and shape were found. There was enormous thickening ofall vessels, the small veins being five times the normal size. The thicken-ing of the wall was mainly in the external coat, the endothelium not par-ticipating. Leucocytes were present in the perivascular spaces, mth isl-ands of young granulation tissue. There was no enlargement of thelymph spaces or of the lymphatics, but, according to the observer, someof the islands occupied by embryonal cells were lymph-vessels or spacesin a state of plastic inflammation—a view which seems very probable.There may be increase in the fatty as well as in the areolar tissue, andendoarteritis as well as periarteritis and pldebitis may be present. Etiology.—The primary cause of elephantiasis in most cases hasbeen shown by Manson, Lewis, Bancroft, and others to be the presence ofthe filaria sanguinis hominis, and this view is shared by Maitland in hisrecent work on Elephantiasis and Allied Disorders.

Elephantiasis of the Scrotum (Morrow.) ELEPHANTIASIS OP THE SCROTUM. 88T Manson believed that all the phenomena of the disease could he ex-plained on this theory. Lewis (Lancet, September 20, 187^) found anadult iilaria worm in a lymphatic vessel of a scrotal elephantiasis. Thefilaria Bancrofti, as it is sometimes called, is a thin, white worm threeto four inches in length and of the thickness of a hair. It is capable oflaying thousands of eggs. It is thought probable that inflammation maybe caused by the chemical products of the excretions of these worms,and in non-epidemic regions that any irritative inflammation, such as thatproduced by erysipelas or syphilis, may have the same result. The secondary cause is obstruction of the lymphatic channels eitherthrough the production of embolism, by the filaria itself or its ova, orby the occurrence of inflammatory obstruction. Mapother (PhiladelphiaMedical Times, I^ovember 15, 1887) explains the frequency of scrotalimplication on the theory
