|Contribution||Described liver-rot in sheep, and the presence of a fluke.|
|Notes||The date is approximate. The account appeared in 'The Black Book of Chirk.' Presumably no suggestion of causation. There is a suggestion that a reference to what is now called fasciolosis may have appeared in a Welsh document of the 10th century. See S. J. Andrews, in Fasciolosis (J, P. Dalton, ed.) CABI Publishing, 1999. Knowledge of parasitic worms undoubtedly goes back to pre-history, but would generally have referred to intestinal worms, which are sometimes passed in feces. This item is included here because it deals with an extra-intestinal parasite.|
