Note 1626 — Chapter LVIII

Printed at Antwerp in 1476 and 1497, at Lyons in 1525, at Frankfurt perhaps in 1567, 1575, 1576, and certainly in 1578, at Paris in 1577. I have used the 1497 edition,—Summa Experimentorum sive thesaurus pauperum magistri Petri yspani, Antwerpiae, Theodoricus Martini, 1497 (die 22 Mai). A letter lying loose in the copy (numbered IB. 50018) which I read at the British Museum, stated that the copy at Liège is (was) the same. I also consulted the edition printed at Frankfurt in 1578 but it seemed faulty compared with the 1497 edition. For a list of MSS see Appendix I at the close of this chapter.
