a town of Hertfordshire in England, seated in E. Long. o. i. N. Lat. 52. 3. It is a large place, seated in a fertile vale full of inns, and the market is very considerable for corn. There was lately discovered, almost under the market-place, a subterraneous chapel of one Rosia, a Saxon Lady: it has several altars and images cut out of the chalky sides, and is in form of a sugar-loaf, having no entrance but at the top.
