[2437] Since on the one hand he cites “master Albert”, while on the other hand there are several fourteenth century MSS of his work.
[2438] Sloane 1754, 14th century, fols. 28r-30r, “Experimenta Fratris Nicholay de Polonia qui fuit in Monte Pessulano 30 annis,” etc.
Berlin 166 (Phillips 1672), 14th century, fol. 21, “Incipiunt experimenta de animalibus fratris nicholai de polonia,” etc. The variant readings in parentheses are from this MS.
CLM 534, 14th century, fol. 75, Experimenta fratris, etc., medici de Polonia qui fuit in Montepessolano.
Sloane 964, 15th century, fol. 82, “Experimentum M. Nicholai de Bodlys qui fuit de Monte pessulano.”
St. Augustine’s, Canterbury 1846 (now missing), Experimenta Nicholai de polonia.
Wolfenbüttel 3489, 14-15th century, fols. 83-135v, Experimenta magistri cancellarii de Monte Pessulano, seems too long to be our treatise; more likely it is the same as BN 7056, Experimenta magistri Gilberti Cancellarii Montepessulani.

[2440] Berlin 166, 14th century, fols. 23-26, “Incipit antipocras quem composuit et similiter noncupavit frater nicholaus fratrum predicatorum, alio autem nomine appellatur liber empericorum.” I have not seen the MS, but follow the description by V. Rose (1893) I, 371-2.
