J 68 Chemistry. [Lecture 29. 



There are other acids, such as the uric (ex- 

 tracted from calculi), the rosacic, the amniotic, 

 and the lactic, or acid of milk, &c. 



The arrangement of the compound or neutral 

 salts under the new chemistry is peculiarly easy. 

 The barbarous jargon of the old school, which 

 meant nothing, such as sal digestivus,* sal mira- 

 bilis, sal polychresti, is banished, and the name 

 now discovers the materials of which the salt 

 actually consists. Thus, when we hear of nitrat 

 of potass, or muriat of soda, no person who 

 knows any thing of chemistry can mistake : but 

 must understand that these mean compounds of 

 the nitric and muriatic acids with potass and 

 soda. 



The different genera of compound salts are 

 denominated from the acids. Thus, we have 

 sulphats, nitrats, muriats, borats, fluats, tar- 

 trats, acetats, phosphats, &c. But it is ne- 

 cessary to remind the student, that where the 

 salt is compounded of the acid, when not fully 

 saturated with oxygen, the compound is di* 

 stinguished by the termination ite. Thus, the 

 sulphurous acid produces sulphits ; the sulphu- 

 ric acid sulphats. 



The species of compound salts are distinguish- 

 ed by subjoining the base ; as sulpbat of soda, 

 which distinguishes the salt from sulphat of 

 lime, or any other sulphat; and as some of the 

 acids will unite with two bases, the triple salt is 

 described by adding both bases, as tartrat of
