Experiments and Obfervations made with the newly difcovered Metallic Pile of StG. Volt A. 

 By Lieut. Cel. Heury Haldane. With Remarks by W. N. 



XmMEDIATELY after the publication of the procefs of Signer Volta in a morning 

 paper *, Col. Haldane, whofe zeal in the profecution of philofophical operation is well 

 known, conftru£led an apparatus, and made a feries of experiments for the purpofe of 

 analyfing the pile itfelf, as well as the nature of its effefts, of which he had the goodnefs 

 to favor me with an account. But as thefe inveftigations, though undoubtedly poflefling 

 the merit of originality, as far as relates to the fcientific acutenefs of their author, were in 

 fome refpefls the fame as others then unknown to him, but poflefling priority in point of 

 aftual date, I poftponed the public notice of his communication, till it fliould have the 

 advantage of his revifal, after perufing the contents of my laft paper. The fame motives 

 at prefent lead me to give an account of the new facts, with a few remarks relative to the 

 theory, of which we are much in want to direft our future operations. 



* Paragraph in the Morning Chronicle of May 30, iSoo, giving an inaccurate account of the hiftory of 

 the invention, and defcribing the general efFeils as exhibited by I>r. Garnet in the lefture at the Royal 

 Inftitutlon.
