ifeyed from a diftance through a tube, but it is very diftinci. 

 The lady converfes in feveral languages, fings, defcribes all 

 that happens in the room, and difplays a fund of lively wit and 

 accompliihment, that admirably qualify her to fupport the cha- 

 racter (lie has undertaken. 



I hope to meet my reader hereafter with a little more to fay Experimentof 

 on the nature of this experiment. At prefent I can only offer found conveyed 



• r> . i r i • ii i i cl i to great diftanc* 



the conjecture that the iound is conveyed through the firings, by a tnreac i, 

 and to this I am led by another experiment of the celebrated 

 Dr. Moyes. He fhewed me, that if one end of a packthread, 

 or even fewing thread, be wrapped round the finger, and that 

 finger be put into the ear (not forcibly) while the other ear is 

 flopped, and at the fame time an affiflant Wraps the other end 

 of the firing round the handle of a tuning fork, and (the firing 

 being then drawn rather tight) he caufes the fork to found, too 

 low to be heard by himfelf and the byflanders, it will never- 

 thelefs be very audible to him Who holds the other end of the 

 firing. We tried it at an interval of fifty feet, and the Doct or 

 has tried it at upwards of three hundred, without any fenfible 

 diminution of the effect. I wrapped the firing round my wriit, 

 and put my finger in my ear, and found the effect very nearly 

 as flrong. If inflead of the tuning fork one obferver bites hold Conversation 

 of the firing between his fore teeth, while the other applies it through a firing* 

 as before to his ear by means of his finger, the voice of the for- 

 mer may be tranfmitted ; but it is more difficult to manage this 

 experiment with fuccefs than the other. 



Aeroftatic Experiments q^Garnerin. 



A new generation has fprung up fince the epoch at which Revival of aerof* 

 Air Balloons conftituted the object of aftonithment and fpecu- tation. 

 iative refcarch about twenty years ago. They who remember 

 that bufy period as if it were yefterday, mufl feel a little fur- 

 prized at the viciflitudes of human affairs, when they find how 

 many of thofe who are now intirely engaged in fociety, were 

 then fcarcely in exiflence ; and how few have feen a balloon. 

 The fpeclacle exhibited by Mr. Garnerin, though much Iefs 

 impreffive than the experiments of his countrymen to whom 

 this invention is due, in all their novelty and originality have 

 neverthelefs been received witli much interefl. The readers Garnerin the 



of our Journal will recollect him as the firft adventurer whofe fil [ ft , °P eratot
