434 On the Capacity for Heat of various Liquids. 



Three experiments made with spirits of turpentine 

 gave the following results : 



Specific heat of turpentine. 



1st experiment 0.29322 



zd experiment 0.37031 



3d experiment 0.34216 



Mean result . . . 0.33856 



Two experiments with alcohol, of the specific gravity 

 of 817,624, gave the following results : 



Specific heat of alcohol. 



1st experiment ....... 0.54924 



ad experiment - * . . . . 0.55063 



Mean result . . . 0.54993 



Two experiments with spirit of wine, of the specific 

 gravity of 85,324, gave the following results: 



Specific heat of spirit of wine. 



1st experiment . . . . " . . . 0.57840 



zd experiment . . . '' . 0.58317 



Mean result . . 0.58078 



Two experiments with sulphuric ether, of the specific 

 gravity of 72,880, gave as results : 



Specific heat of sulphuric ether. 



1st experiment ....... 0.53711 



2d experiment . ' . . ' 0.54768 



Mean result ... * 0.54329 



I was at first much surprised to find so great a ca- 

 pacity for heat in sulphuric ether, but my astonishment 

 was diminished when I recollected that this liquid can 

 unite with alcohol in all proportions without exhibiting 

 any symptoms of a chemical action ; for this reason, 

 therefore, we ought to expect to find the same capacity 

 for heat in both liquids.
