Kr^ Acts of the British Legislalurc. [Aug. 1, 



Italy. 



It is well known that when n current 

 of inllaminable air, projected by a pipe 

 only a fc'v lines in dia'iicter, is burned 

 under a gkif^ tube, yon hear certain har- 

 monious, but very fliriil, fi)uiuls, which 

 pert'ccily refemble thole ot" the harmo- 

 nica. An Itahan philofopher has recent- 

 ly obfervcd an cllcct which bcar.i a great 

 anaiotfy to this phenomenou. Melting, 

 at the lamp of an euan^cller, a glafs tube 

 •wet in the iniide^ to blpw wjth it the bulb 

 ot" a thermometer, it emitted a found 

 which lafied ieveral feconds, confta)Uly 

 increaling in loududs, but«h:ch could be 

 flopped by clofmr; with the iinger the 

 open ext.emitv of the tube. The ex- 

 planation nnilt appartntly be the fame 

 in both cafes. In the tint, the combuf- 

 tion of hydrogen gas with a part of the 

 atmofpheric air Ibrnis, every monient, a 

 very hot aqueous vapour, which by the 

 fpeedy diffipation of the heat ia condcnf- 

 ed into water. Accordingly fmaJl vacuums 

 are rapidly formed in the air, and as ma- 

 ny fuccelhvc approximations of its parts ; 

 and thele fudden alterations produce in 

 the .'lir ofcillations like thofe ariiing from 

 the coUition of a fonorous body. In the 

 fecond cafe, bv cauling the humidity to 

 pafs from the tube into the heated bulb, 

 the vapour is fucofffively formed and de- 

 compolbd there at very iliort intervals, 

 and j)roduces a llmiiar found iu the 

 tube. 



America. 



Mr. Thomas Kvvei.l, an American 

 farmer, announces in the Xciv York pa- 

 pers I'ome fucccfsful experiments which 



he has made vith powdered coal as a 

 manure. He fays, that 16 buflicls of 

 coals in lumps make 24 in powder ; but 

 he omits to inention the quantity which 

 he applied per acre. 



1 he following atteftation lately appear- 

 ed in a New York paper, relative to a 

 local appearance of Aurora Borealis : 



•' On Sunday evening, the l.ilh ol Sepfein- 

 ber laft, between I'evcn and eiglit in the 

 evening, from tlie windiiw^ of the ]?cv. M,r. 

 Grofs's honl'e in ILirtfotd Vermont, we no- 

 ticed the .Aurora Borealis; the bottom of it 

 elevated but a few degrees above the hori- 

 zon, lay in a regular line, very bright, and 

 not nuich wider than the rainbow; above 

 that, in feveral places ftreamslhnt up towards 

 tlie zenith as ufual. We had not viewed it 

 long before we obferred the eaftern part of 

 it had fettled fo lov.- as actually to be be- 

 tween us and the high land on the north fide 

 of White River, the height at tlie'diftanoe 

 from us perhaps of about one mile and a 

 hall". The meteor muft have b«en nearly 

 perpendicular to White River, and diftimt 

 perhaps about half a mile. Tt would have 

 gratified our curiofity could fome of us have 

 been on the height beyond White River, to 

 have made our obfervations npon it, as it 

 muft have been between us. This »e cer- 

 tamly concluded, that it would be needlcfs 

 for us to go to tlie north p If for it. 1 here 

 had been confiderable rain the precedirig 

 day, the air was warm, and fome tog towards 

 evening lay along upon the White River, and 

 the luminous meteor rather appeared to be 

 intermingled in the foj."
