If your correspondent will refer to the word _Parvisium_, in the Glossary
at the end of Watt's edition of Matthew Paris, he will find a good deal of
information. To this I will add that the word is now in use in Belgium in
another sense. I saw some years since, and again last summer, in a street
leading out of the Grande Place, by one side of the Halle at Bruges, on a
house, this notice,--
"IN PERVISE
VERKOOPT MEN DRANK."
