The fuel to be employed has been already 
mentioned under that article, and a supply 
should be kept near at hand, broken down 
ready for use. 
With regard to the different substances 
or re-agents to be kept, the chemist will, 
of couree, wish to have a specimen of all 
the simplp or individual substances, such as 
the acids, earths, metals, &c. but the sim- 
ple 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 quan- 
tity of potash in common sulphuric acid, 
and of iron in common muriatic acid, sel- 
doita 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 phemist will 
therefore find it of advantage to reserve a
