One Sunday in March, between the early and the latter rains, Miss Northrop and Will Strong walked out together several miles over the plain. The gravel had long disappeared under green burclover and filaria, thickly dotted with the little yellow clover blossoms, the lilac ones of the filaria, and with small blue gilias.
If we imagine the parent filaria located in a distal lymphatic vessel to abort and give birth to ova instead of embryos, it may be understood that the ova might be unable to pass such narrow passages as the embryo could, and this is really the hypothesis which Manson has put forward on the strength of observations made on two cases.
There was evidently a good stiff epidemic of the yaws about; lots of cases of dum with the various symptoms; ulcers of course galore; a man with a bit of a broken spear head in an abscess in the thigh; one which I believe a professional enthusiast would call a "lovely case" of filaria, the entire white of one eye being full of the active little worms and a ridge of surplus population migrating across the bridge of the nose into the other eye, under the skin, looking like the bridge of a pair of spectacles.
Manson deals with the phenomenon known as "filarial periodicity," and with the fate of embryo parasites not removed from the blood. The intimate pathology of the disease, and the subject of abscess caused by the death of the parent filaria, also receive further attention.
It passed us, burying one of my camels. As soon as we rose from the earth, with uplifted hands for its preservation, we awoke to fresh horrors. Its parching tongue had lapped the water from our water-skins, and having escaped the fiery hour, we had to fear the still more awful death of thirst." This disease is the Filaria Medinensis, or Guinea Worm.
She ran upon the bluffs, and looked northward, but there was neither horse nor wagon visible. The mother, and children had evidently resumed their journey very early, and the turns of the country roads had hidden the travelers. They had vanished forever. "God guide them to the River!" whispered Addie. A boy was walking through the filaria.
Of these entozoa, the Filaria medinensis, or Guinea-worm, which burrows in the cellular tissue under the skin, is well known in the north of the island, but rarely found in the damper districts of the south and west.
An interesting type of lymphangiectasis is that which results from the presence of the filaria Bancrofti in the vessels, and is observed chiefly in the groin, spermatic cord, and scrotum of persons who have lived in the tropics.
But to return to those preventive measures, and having done what we can with the air, we will turn our attention to the drinking water, for in addition to malarial microbes the drinking and washing water of West Africa is liable to contain dermazoic and entozoic organisms, and if you don't take care you will get from it into your anatomy Tinea versicolor, Tinea decalvans, Tinea circinata, Tinea sycosis, Tinea favosa, or some other member of that wretched family, let alone being nearly certain to import Trichocephalus dispar, Ascaris lumbricoides, Oxyuris vermicularis, and eight varieties of nematodes, each of them with an awful name of its own, and unpleasant consequences to you, and, lastly, a peculiar abomination, a Filaria.
Our readers are probably aware that the parent filaria and the filaria sanguinis hominis may exist in the human body without entailing any apparent disturbance. The diameter of an embryo filaria is about the same as that of a red blood disk, one three-thousandth of an inch. The dimensions of an ovum are one seven-hundred-and-fiftieth by one five-hundredth of an inch.
