Note 1. GAS. 



Gas is an aeriform fluid, composed of two parts. 1. 

 The particular substance that is converted into gas, by 

 heat or caloric. 2. The Caloric, which, by its chemical 

 combination with the basis, constitutes a gas, or perma- 

 nently elastic fluid, capable of existing in an aeriform 

 state, under the pressure, and at the temperature of the 

 atmosphere. 



To form a gas, or permanently elastic fluid, a chemical

combination must take place between the caloric and the 

 substance, at the time of its being converted into a gase- 

 ous state. This combination cannot be destroyed, except 

 by the aid of some chemical agent that has a stronger 

 affinity for either of the constituents of the gas. 



Vapour is an elastic fluid, bearing a strong resemblance 

 to a gas ; but vapour is nothing more than the solution, or 

 mechanical division, of any substance whatever in caloric. 

 Caloric in vapour is only latent, and not chemically com-
