The fuel to be employed has been al- 

 ready mentioned under that article, and a 

 supply should be kept near at hand, 

 broken down ready for use. 



With regard to the diflerent substances 

 or re-agents to be kept, the chemist will, 

 of course, wish to have a specimen of all 

 the simple or individual substances; such 

 as the acids, earths, metals, &c. but 

 the simple and compound substances 

 which are of general use, ought also to 

 stand on the shelves. 



For many purposes the ordinary degree 

 of purity in which these substances are 

 obtained by the common processes are 

 sufficient; so, for example, the small 

 quantity of potash in common sulphuric 

 acid, and of iron in common muriatic 

 acid, seldom interferes with any of the 

 uses to which those re-agents are applied ; 

 but it is also necessary frequently to have 

 them in the utmost purity when employed 

 as tests for delicate purposes. The che- 

 mist will therefore find it of advantage to 

 reserve a separate set of a few of the most 

 necessary re-agents in their utmost puri- 

 ty, and if only employed when absolutely 

 required, a very moderate quantity will 

 suffice. In the subjoined list we have 

 distinguished by the word pure those sub- 

 stances which require particular pains to 

 be obtained absolutely pure. Mixtures 

 of each of the stronger acids and water 

 in two or three different and known pro- 

 portions should also be kept. 



N. B. The letter D implies, that the dry- 

 substance should be kept, and S, that it, 

 should be in solution,
