«hfccs a foamy effervefcence, gives out nitrous gas, and dif-^ 

 folves. This folution is decompofed by water, like that of 

 animal Hbrous matter, and the white precipitate thence re- 

 fulttng ditlblves in ammonia, affuming a dark yellow co- 

 Imir. 



3. A difcoreryof two new principles in fulphureous wa- 

 ters has lately been made by Counfellor Weftrumb, of 

 Hammein, who gives the following details : 



" For fix years I have been exclnfively employed in tfie 

 analyfis of fulpbureous waters. I have found an eafy and en- 

 tirely new method of determining what thev contain of 

 fulphurated hydrogen and carbonic acid gas ; and 1 have 

 tlifcovered a principle hitherto unknown in thefe waters, 

 namelv, bitumen in combination with fulphurated hydro- 

 gen gas and hvdro-fulphurated lime. I communicated the 

 detail of this difcovery to M. Wurzer. Counfellor Von CrtU 

 and Profefl'or Schaub of Caflel faw at my houfe thefe new 

 produfts. Thefe principles are found in the waters of 

 Neiiwdorf, Limmen, RehbuFff, and Evlfe. In the lali 

 place, five fulphureous fprings, ahoofether difierent from each 

 other, a fpring of carbonic gafeous water, and one of freOj 

 ■water, are found in an extent of Icfs than a thoufand fquare 

 feet. Near Buckembonrg, the capital of the fmall country 

 of Leppe, to which Eylfe belongs, are found two other ful- 

 phureons fprings perfectly fimilar, one of which Ave founded 

 to the depth of eighty feet without finding its refcrvuir. 

 Baths of mud fimilar to thofe of St. Amand have been con- 

 ftriicted :U Eylfe: a very confiderable quantity of hydro-ful- 

 phiirated mud, vihich may furnlfh baths for feveral cen- 

 Iwries, has been found there." 



4. A new gas, fulphurated azotic gas, has been difcoveretl 

 in the mineral waters of Aix-la-Chapelle by M. C Gim- 

 bernat, fub- director of the mufeum of natural hiftory at 

 Madrid, who gives the following account of it : 



" I have jufl: finiflied my labour on the analyfis of the 

 fidphurcous waters of Aix-la-Chapelle. I have found that 

 the cxcipient of the fulphur in thefe waters is not hydrogen, 

 as has hitherto been fuppofed and afferted, but azote. Thefe 

 waters contain no fulphurated hydrogen. 



" Sulphurated azotic gas is a chemical bodv, the ex- 

 iftence of which has never been fufpefted. Nature pre- 

 fents it in abundance in the mineral waters of this country. 



" Befides fulphurated azote, thefe waters contain a great 

 deal of pure and free azote interpofed, and in the f^mi- 



gafeoufci ftate.'*
