"The King holds CAMBRIDGE. There are 10 wards. In the time of King Edward there were 373 burgesses paying all customs. Now there are 100 less 1 burgesses, and 100 more less 1 who pay the full custom, and 70 who pay half custom. Picot the sheriff has 3 domus who pay custom in all things. The burgesses say that from the time when Picot came to the sheriffdom, he unjustly took their common pasture. The churches of that borough are St Benet's and All Saints', which King Edward always had as two manors."
