The above second edition is as rare as the first, and perhaps preferable to it on account of its typographical execution. 

 The author, perhaps better known as Litca di Borgo [or BurgoJ, the name he took on entering religion, was the first to 

 introtluce symbols in algebra. 



' In the arithmetic Pacioli gives rules for the four simple processes, and a method for extracting square roots. He 

 deals pretty fully with all questions connected with mercantile arithmetic, in which he works out numerous examples, and 

 in particular discusses at great lengtli bills of exchange and the theory of book-keeping by double entry. This part was 

 then the first systematic expohition of algoristic arithmetic. ... In the algebra he discusses in some detail simple and 

 quadratic equations, and problems on numbers which lead to such equations. He mentions the Arabic classification <>f 

 cubic e<iuations, but adds that their holution appevrs to be as imi)Ossible as the quailrature of tlie circle. . . . Though 

 much of the matter described is taken from Leonardo's Liber AliacL, yet the notation in which it is expressed is sui)erior to 

 that of Leonardo,' etc. etc. etc.— Jf'. W. R. Hall. 



' In the mathematical writings of the monk Luca Pacioli symbols began to appear. They consisted merely in abbrev- 

 iations of Italian words, such as p for pin, m for mcno, co for cona . . . ' — Prof. Lojori. 



' II y a dans ce grand recneil une methode fort ingenieuse pour la resolution de plusieurs equations indeterminees du 

 second ou du quatrieme dcgre. ... On y voit la re.solulion des equations derivees du second degre, et oelle de certaines 

 c*(luations exponentielles. Dans quelques problemes relatifs a la itgle des partis, le calcul des probabilites se montr« 

 pour la premiere fois. . . . Eutin on y trouve I'application de lalgebie u la geometric et une multitude de faits, relatifs a 

 diverses branches des connais-sances humaines et fort utiles aux personnes qui veulent etudier I'histoire des sciences. 

 C'est, par example, dans un traite de commerce insere dans cette Somme, que I'ou trouve pour la premiere fois la tenue 

 des livres en partie double,' etc. etc. etc. — G. Lihri.

This was perhaps the first suggestion lor a monorail line, as afterwards retluced to practice on the Lartigue system, as 

 on the Listowel and Ballybunion Railway. It was to follow the contour of the country, slightly raised on posts or trestles, 

 the trucks being drawn by a horse walking beside it. One plate gives a general view of the line, and the other con- 

 structional details. The resistance tables are compiled from the Cheltenham, Llanelly, and other tramroads of the time. 



The work is not mentioned by AUibone, nor can anything be traced concerning its author.
