P.S. Since I wrote the above, I have found in the Sale Catalogue of the
Towneley library, 1814, pt. i. lot 396.:
"_Seguardi Opuscula._ Manuscript on vellum. This volume contains
several treatises not mentioned by Bale or Pits."
It was purchased by Mr. Laing for 1l. 1s. May I, therefore, add one more
Query?
5. Can the present owner of this MS. (which is probably the same as the
Langley copy) furnish a note of its contents?
