tista, da Fabriano) SCANDAGLIO sopra la LIBRA ASTRONOMICA et FILOSOFICA di LOTARIO 

 SARSI, nella Controversa della Comete, e particolarmente delle Tre ultimamente, vedute 1'Anno 1618 

 2 vols. sm. 4to. in 1, old limp vellum (large copies) ; RARE, 1. 10s Perusice, 1619 Terni, 1622 



The first work was an attack on Galileo's supposed opinion on the nature of comets, as expressed by his disciple 

 Guiducci, and is important as haying provoked Galileo's crushing reply in his II Saggiatore (v. No. 8221 ante). 

 The second is a reply to Grassi.

The author's answer to Galileo's II Saggiatore (v. No. 8221 ante). Grassi was one of the chief movers in Galileo's 

 prosecution. 



8588 GRASSMANN (Hermann Gunther) Die AUSDEHNUNGSLEHRE, vollstandig und in stronger 

 Form bearbeitet, 8vo. hf. calf gilt (nice copy) ; scarce, 7s 6d Berlin, 1862 



An enlargement and continuation of this classical work originally published in 1844. 'His researches on non- 

 commutative algebras are contained in his Ausdehnungslehre. This work has had great influence, especially on the 

 continent, where Grassmann's methods have generally been followed in preference to Sir W. R. Hamilton's .

 sm. 4to. in 1, fine copy in old Italian vellum, 1. 10s Venetia, 1680 



VERY BARE, and apparently unknown to Mr. Richard Brown, who does not mention the work in his ' Bibliography of 

 Bookkeeping', while Prof. Riccardi, who had seen no copy of it, merely quotes it on the authority of Cicogna's Saggio. 

 There was also no copy in the Libri Library.
