Refutatkn de la Thhr'it Pmumatiqr/e, (sfc. A Refutation of the Pneumatic Theory, 

 or the New Do£lrine of the Modem Chemifts, prefcnted Article by Article, in a Series of 

 Replies to the Principles colletlcd and publiflied by Cit. Fourcroy in his Philofopliie Chi- 

 mique : to which is prefixed, a Complementary Supplement to the Theory cxhilKted in a 

 Work entitled Rickerches fur la Catfet dtj Principaiix Fait! Ph\fiqties ; or, Rcfearchcs into 

 the Caufcs of the Principal Phyfical Fafts, to which this forms a neceflary Continuation, 

 By J. B. Lamarck, of the National Inftitute of France. 0£tavo, 48 1 pages . Publiflied at 

 Paris, by the Author, at the Mufeum of Natural Hiftory ; and by Agaflc, rue dcs Poitcvins.

I have not yet procured the Recherche: here mentioned ; but, when in poflcdion of both, 

 it will become an object of careful enquiry, whether an abftract of the leading points 

 of difTereiice in this author's theory and that which he attempts to refute may be of value to 

 the fcientific world. 



Specimens of Britifti Minerals felefted from the Cabinet of Philip Rafhleigh, of Mena- 



billy, in the county of Cornwall, Efq. I\d. P. F. R. S. and F. A. S. with general defcriptions 



. of each article: 4to — 56 pages — 33 plates coloured. Nicol and White. Price 2I. 12s. 6d. 



This magnificent work difplays with great efTeft the fpecimens, chiefly confiding of tin, 

 copper and lead ores, with calcareous fpars and quartz. 1 he defcriptions are intended to 

 complete the knowledge, in part and very ftrikingly, conveyed by the plates. Little is faid 

 in general concerning analyCs, or the component parts. 



Cit. Prony, of the French National Inftitute, has publiflied the fecond part of the Nouvelte 

 Archileclure Hydraulique. This part contains the defcription of fteam engines. It is fold by 

 Firmin Didot, No. 1 16, rue de Thionville. Quarto, 240 pages, with 40 plates. Price 40 liv. 



M. Lalande, in the Journal des S5avans page 125, gives the following account of this work: 

 " Since the appearance of the firft part of the Architedlure Hydraulique in 1790, the pub- 

 lic has jvaited with impatience for the continuation. This part is a complete Treatife on 

 Steam Engines. It contains new experiments on the expanfive power of heat ; an account 

 of pumps which have the pifton afted on by the fteam alternately on both fides (pompesa 

 double effet), and thofe which are firaple ; inftruclions for difpofing the latter to a£l in the 

 manner of the former ; the theory of the right-lined motion of the pifton by a combination 

 of ciicular movements; and a method of interpolation applicable to phenomena which 

 depend on cbftic fluids. The analytic part of this work is no lefs curious than the mecha- 

 nical and experimental parts. No one but a geometer could have treated thefe fubje£ls in a 

 manner fo perfpicuous for the learned ; nor could a lefs able engineer have rendered them 

 fo fatisfadlory to pradlical men." 



Citizen Gamier, ProfefTor of Mathematics, has added feveral ufeful explanations of parts 

 «f the firft volume of Citizen Prony, which render this work ftill more complete.
