' The investigations of the Count de Pambour on the theory of the steam engine were conducive to the progress of 

 thermodynamics by pointing out the proper mode of applying mechanical principles to the expansive action of an elastic 

 fluid.'— Pro/. Eanrhw, F.R.S. 



M. de Pambour is unaccountably left out of the Nonvdhi Bioqraphu General'-, 1SG2, although, living in the midst of 

 the Romantic Period, he was a pioneer of workaday progress in France,

J. Guignard, 1698 

 This copy belonged to J. Eliot Hodgkin, f.s.a., and bears his bookplate, and some MS. additions. According to his 



authority, the work is ' exceedingly rare, as it is one of the most important books for the history of the Steam Engine. 



In it is contained" the remarkable mention of a high-pressure steam-engine for driving paddles for the propulsion of a 



vessel, on which is based by French writers the claim of Papin to the invention of the steam-engine.' 



The work is also of great importance for containing Papin's invention of the centrifugal pump. Added is an 



interesting acf^ount thereon by Mr. Hodgkin, as published in Engineering for 1890. It was unknown to Querard, 



Poggendortt". Bioqr. Ghi., and other bibliographers, and is of great rarity.

The second work is rare, and interesting for containing Father Pardies's discovery of two dialling machines, by means 

 of which (according to the preface) 'on peut apprendre, en moins d'une heure, la maniere de faire toutes sortes de 

 quadrans, et qu'on peut pratiquer, comme en se joCiant, ce qu'on a appris, et faire sur les murailles, et dans les chambres, 

 toutes sortes d'horloges, avec une tres-grande facilite.'
