No prior complete English translation of this text has been found.

The work 'Opera hactenus inedita' is a multi-volume series edited by Robert Steele (and others) that collects various previously unpublished works of Roger Bacon. 'Fasciculus 13' refers to a specific installment in this series. My searches confirm that while some volumes of the 'Opera hactenus inedita' series have been digitized and discussed in academic contexts, there is no evidence of a complete English translation of Fasciculus 13. The search results for 'Opera hactenus inedita' generally point to the Latin editions themselves, and no specific English translation of the 13th fasciculus exists.
