 The earliest issue of the first edition or the first v/ork treating exclusively of bookkeeping. All editions of 

 the work are of great rarity, but the above is exceptionally so. It is quite unknown to bibliographers, e.g., Riccardi, 

 Brunet, Graesse, etc., nor is there a copy in the British Museum or in any other great public library. 



The lirst author to refer at all to the 1525 edition is Mr. Richard Brown, who in his History of Accoiivting and 

 Acco^intantx, mentions an edition in 24 11. of this date, which actually forms a later issue of the above edition. The above 

 edition in 16 leaves, however, is quite unknown to bibliographers, nor with the sole exception of this and another copy in 

 a London Professional Library, can any copy be traced as being still in existence. 



4723 : Considerando Io Giovann' Antonio Tagliente quanto e necessaria cosa a li nostri 



Magnifi [sic] gentilhuomini »& ad altri mercatanti il laudabile modo da tenere conto de libbro

 water- stained, otherwise a SOUND copy) ; very rare, £5. 5s 



[col. .•] Vinegia, per Giouann' Antonio di Nicolini da Sabio, 1533 

 This edition was unknown to Mr. Richard Brown. It consists of 36 11., signatures A-D in eights and E in fours. 



4724 [ ] Libro di Abacho il quale insegna a fare ogni ragione mercantile «!s: pertegare le terre.

 rispondeno i pesi, & Monede, di molte Citta »S: Paesi, con la inclita citta di Venetia. II quale 

 Libro si chiama Tesoro Uniuersale ; title in red ivithin woodcut border, with large woodcut of a 

 Business College on rev., and numerous smaller woodcuts and ornaments throughout, 16mo. old 

 painted wrapper {a few II. mended on blank margin, and a few others slightly gnawed, but a sound 

 copy) ; very rare, £3. 15s [col. ;] Venetia per Francesco de Leno, 1570 



Of great rarity, like all the editions of Tagliente's Abaco. The above edition was unknown to Brunet. 



It is a remarkable fact tliat, althougti Tagliente was one of the earliest and most important writers on commercial 

 arithmetic, hardly any copies of any editions are left at the present time. This rarity may account for the fact that these 

 works were unknown to bibliographers of scientific works, as Montucla, Poggendorff, Prof, de Morgan, etc., and that no 

 biography of either Tagliente can be found in any biographical dictionary.
