the factor in the
production of the well-known hydatid cysts which may be found in any
part of the body. Delafield and Prudden report the only instance of
multilocular echinococcus seen in this country. Their patient was a
German who had been in this country five years. There are only about
100 of these cases on record, most of them being in Bavaria and
Switzerland.

The filaria sanguinis hominis is a small worm of the nematode species,
the adult form of which lives in the lymphatics, and either the adult
or the prematurely discharged ova (Manson) block the lymph-channels,
producing the conditions of hematochyluria, elephantiasis, and
lymph-scrotum. The Dracunculus medinensis or Guinea-worm is a
widely-spread parasite in parts of Africa and the West Indies.
According to Osler several cases have occurred in the United States.
Jarvis reports a case in a post-chaplain who had lived at Fortress
Monroe, Va., for thirty years. Van Harlingen's patient, a man of
forty-seven, had never lived out of Philadelphia, so that the worm must
be included among the parasites infesting this country.

In February, 1896, Henry of Philadelphia showed microscopic slides
containing blood which was infested with numbers of living and active
filaria embryos. The blood was taken from a colored woman at the
Woman's Hospital, who developed hematochyluria after labor. Henry
believed that the woman had contracted the disease during her residence
in the Southern States.

Curran gives quite an exhaustive article on the disease called in olden
times "eaten of worms,"--a most loathsome malady. Herod the Great, the
Emperor Galerius, and Philip II of Spain perished from it. In speaking
of the Emperor Galerius, Dean Milman, in his "History of Latin
Christianity," says, "a deep and fetid ulcer preyed on the lower parts
of his body and ate them away into a mass of living corruption."
Gibbon, in his "Decline and Fall," also says that "his (Galerius's)
death was caused by a very painful and lingering disorder. His body,
swelled by an intemperate course of life to an unwieldy corpulence, was
covered with ulcers and devoured by immense swarms of those insects who
have given their names to this most loathsome disease." It is also said
that the African Vandal King, the Arian Huneric, died of the disease.
Antiochus, surnamed the "Madman," was also afflicted with it; and
Josephus makes mention of it as afflicting the body of Herod the Great.
The so-called "King
