228 APPENDIX A. 



which solid bodies have been placed; measure the 

 temperature when it has become uniform. See if 

 it is the same as in the reservoir. Same experi- 

 ments with other gases and with vapor formed 

 under different pressures. 



To repeat Dalton's experiments and carry them 

 on to pressures of thirty or forty atmospheres. To 

 measure the constituent heat of the vapor within 

 these limits. 



Id. on the vapor of alcohol, of ether, of essence 

 of turpentine, of mercury, to prove whether the 

 agent employed makes any difference in the pro- 

 duction of motive power. 



Id. on water charged with a deliquescent salt, 

 the calcium chloride, for instance. 



Is the law of tensions always the same? To 

 measure the specific heat of vapor. 



Experiments to le made on the Tension of Vapors. 



A graduated capillary tube filled with water, 

 mercury, or with oil and air. Plunge this tube 

 into a bath of oil, of mercury, or of melted lead. 

 To measure the temperature by an air thermometer. 



Same experiments with alcohol, ether, sulphide 

 of carbon, muriatic ether, essence of turpentine, 

 sulphur, phosphorus.
