FIRST EDITION of the work containing the author's invention of continued fractions. 'The rule for the square root is 

 exhibited in the modern form, and Cataldi shews himself a most intrepid calculator. But the greatest novelty of the book 

 is the introduction of continued fractions, then, it seems, for the first time presented to the world. Here Cataldi reduces 



the square roots of even numbers to continued fractions of the form a+ m . . .' Prof, de Morgan.

 translated by JOHN LEAK, with engraved title and 26 plates, besides woodcuts, folio, boards (title, 

 2 II. and 1 plate mended, and small corner torn off 3 plates, otherwise a LARGE AND CLEAN COPY), 

 with Shadiuell Court Library bookplate, 5. 10.9 J- Moxon, 1659 



THE VERY RARE ORIGINAL ENGLISH EDITION, unknown to Lowndes and Watt. The machines described are chiefly 

 based on the hydraulic theorems published by SALOMON DE CAUS, the author's father (q. v. infra). They include engines 

 ' to raise water by means of falling water ' (a 'favourite perpetuum mobile), 'to counterfeit the voice of small birds by means 

 of water and air', 'an Engin which shall move of itself (worked by the expansion of air, heated by the sun, and therefore a 

 prototype of the steam engine), ' to represent divers birds which shall sing diversly when an owl turns towards them,' 'to 

 make organs to sound alwaies when the sun shall be south ', and many other ingenious contrivances. Pp. 1-16 comprise an 

 explanation of hydraulic principles, illustrated by woodcuts. It would be unkind to perpetual motioners to dwell on this 

 work on Water-works being translated by a Leak !

FIRST EDITION of this celebrated Avork. ' In the first part occur his enunciations of the theorems of the expansion and 

 condensation of steam, and of the elevation of Avater by the application ot heat, whioh have gained for him in some quarters 

 the honour of being the first inventor of the steam engine ... It is almost certain that Edward Somerset, 2nd Marquis 

 of Worcester \_q. v. post], to whom this honour has also been ascribed, and later engineers, kneAV and developed the 

 principles enunciated by de Caus.' D. 2V. B.
