Pandolfino's book [Footnote 1: _Pandolfino, Agnolo_, of Florence. It
is to this day doubtful whether he or L. B. Alberti was the author
of the famous work '_Del Governo della Famiglia_'. It is the more
probable that Leonardo should have meant this work by the words _il
libro_, because no other book is known to have been written by
Pandolfino. This being the case this allusion of Leonardo's is an
important evidence in favour of Pandolfino's authorship (compare No.
1454, line 3).],--knives,--a pen for ruling,--to have the vest
dyed,--The library at St.-Mark's,--The library at Santo
Spirito,--Lactantius of the Daldi [Footnote 7: The works of
Lactantius were published very often in Italy during Leonardo's

sublacensi_" was also the first book printed in Italy.],--Antonio
Covoni,--A book by Maestro Paolo Infermieri, --Boots, shoes and

Learn the multiplication of roots from Maestro Luca;--my map of the
world which Giovanni Benci has [Footnote 25: Leonardo here probably
alludes to the map, not executed by him (See p. 224), which is with
the collection of his MSS. at Windsor, and was published in the
_Archaeologia_ Vol. XI (see p. 224).];-Socks,--clothes from the
customhouse-officier,--Red Cordova leather,--The map of the world,
of Giovanni Benci,--a print, the districts about Milan--Market book.

Get the Friar di Brera to show you [the book] '_de Ponderibus_'

600, note 9.],--

The book on celestial phenomena by Aristoteles, in Italian [Footnote
25: _Meteora_. By this Leonardo means no doubt the four books. He
must refer here to a MS. translation, as no Italian translation is
known to have been published (see No. 1477 note).],--

Try to get Vitolone, which is in the library at Pavia [Footnote 26:
_Vitolone_ see No. 1506, note.
