Black Book of Paisley and Other Manuscripts of the Scotichronicon 
With a Note Upon John De Burdeus or John De Burgundia, Otherwise Sir John Mandeville, and the Pestilence

Whilst the greatest effort has been made to ensure the quality of this text, due to the historical nature of this content, in some rare cases there may be minor issues with legibility. I was long puzzled to ascertain anything regarding John de Burdeus, the author of the Tract de Pestilentia, which is copied on a fly leaf of the ms. And as no account of him exists in any Book of Reference, so far as I know, I collected in Note B what I had found. This had been printed when I read Mr. Edward B. Nicholson’s interesting letter in the Academy of 12th April, 1884, identifying him with Sir John Mandeville. I have added a few paragraphs to my Note, embodying the new information, and connecting it with my own but now that Mr. Nicholson has given the clue, it is to be hoped that either he or some other labourer will follow it up and unravel more fully the history of this mysterious personage.
