THETFORD, a market town of England, in the county 
of Norfolk, situated in a pleasant open country, on the river 
Ouse, at its confluence with the Thet, which runs through if. 
The greater part of the town is in Norfolk, but part of it is 
also in Suffolk. The Suffolk side contains now only a few 
houses, but on the Norfolk side there are several streets of 
considerable extent; and of late years the town is much im¬ 
proved in its general appearance. Thetford is a very ancient 
burgh; but its charter of incorporation, by which it is still 
governed, was granted by queen Elizabeth in the year 1573. 
The corporation consists of a mayor, 10 aldermen, 20 com- 
mon-councilmen, a recorder, town-clerk, sword-bearer, and 
two serjeants-at-mace. It sends two members to parliament. 
The town has been honoured with the presence of many of 
our sovereigns, particularly Henry I. and Henry II. Several 
charters granted by the former monarch bear date at Thetford.

bitants. Market on Saturday, and two annual fairs; 29 miles
