Cadaver sanguisugus 

Hi, do you have a scholarly source for the term "cadaver sanguisugus" having been used at least once by William de Newburgh or anyone else? I notice that there are a lot of Google hits on vampire forums etc., but according to this paper, only the word "sanguisuga" occurs, and it is translated by historian James Carley as "a leech". In the Medieval sourcebook edition of Newburgh, the sentence reads "The young men, however, spurred on by wrath, feared not, and inflicted a wound upon the senseless carcass, out of which incontinently flowed such a stream of blood, that it might have been taken for a leech filled with the blood of many persons."
