This work will be confidered as an excellent ftore of faiSls, relative to a great artifl and 

 worthy man. I am forry that there has been fo much controrerfy refpecling them, that I 

 cannot with any fairnefs give an abridged ftatement of the narrative of Mr. Mudge, with- 

 out entering into an ample field of difcuffion and enquiry, as to what may be faid by his 

 opponents. The impartiality of a journalift would require this ; and I think that however 

 interefli^g the fubject may be to a certain part of the public, it would fcarcely be enough 

 fo to juftify the detail in our work. The title will ftiew the value of this performance in 

 thofe refpe£ls which can form no grounds of difpute. 



An EJfay on EleBricity, explaining the Principles of that ufeful Science, and defcribing the In- 

 flruments contrived to illuflrate the Theory, or render the Practice entertaining. Illuflrated 



•withrftx Plates ; to which is added a Letter fo the Author from Mr. fohn Birch, Surgeon, 

 ] on the SubjeEl of Medical Electricity. By the late George Adams, Mathematical Injlrument 



Maker. Fifth Edition, -with Corrections and Additions. By William Jones, Mathematical 



Injlrument Maker. Od:avo, 584 Pages, with an Index. London, fold by the Editor,

This new edition of Mr. Adams's very ufeful and entertaining colleftion of ele£i:rical 

 fafts'and experiments, is confiderably improved by extending fome of the defcriptions, 

 fupplying omiffions, and inferting fuch ,difcoveries, particularly thofe concerning the 

 Doubler, the Plate Machine, and Galearies, as have been made fince the time of the 

 Author, and were indifpenfibly neceflary to bring the treatife to the level of our prefent 

 knowledge of the fubjeft.
