Lamb's Conduit Street
(London). Stow says, “One William Lamb, citizen and clothworker, born at Sutton Valence, Kent, did found near unto Oldbourne a faire conduit and standard; from this conduit, water clear as crystal was conveyed in pipes to a conduit on Snow Hill” (26th March, 1577). The conduit was taken down in 1746.
