This is a fact very difficult to account for. When, and how did the _seed_ of the worm get access to the belly of the child? He rejects the opinion that the rings of the broad lumbricus (tænia) which are passed from the bowels are its offspring. He says it does not occasion death, but continues to live as long as the man lives. Aristotle divides intestinal worms into the lumbrici teretes, the l. lati, and ascarides. He remarks that the broad produce something resembling the seeds of the gourd. He believed in spontaneous generation. The pomegranate seems to have been a popular remedy for intestinal worms. Cato the Censor gives directions for medicating wine by the addition of pomegranate and fennel, of which, he says, “Id vinum tinias perpurgat et lumbricos, si sic concinnes.” (De re rust. 127.) Celsus treats of the lumbrici lati and teretes. For the cure of the former he recommends a draught containing lupine and the bark of mulberry, with the addition of hyssop, pepper, or scammony. He also recommends emetics with garlic, or pomegranate rind with some nitre. For the teretes he recommends the same, and also the seed of nettle, or of cabbage, or mint, or wormwood, or hyssop with mead, or the seed of cresses with vinegar. He advises, likewise, to eat garlic, and use clysters of oil. Scribonius Largus directs first garlic and old soft cheese to be eaten, and then Macedonian fern to be taken with honey. After four hours a mixture of aloes and scammony with honied water is to be given, and a clyster of warm water administered. He also recommends wormseed and the shavings of hart’s horn. Marcellus mentions the same remedies. Serenus Samonicus recommends hartshorn, calamint, garlic, southernwood, coriander, pennyroyal, horehound, &c.
