principles of bodies, may likewise open to our view harmonious 
analogies between the constitutions of related objects, general 
laws, &c. which at present totally escape us. In short, if it is 
founded in truth, its enabling the application of mathematics to 
chemistry, cannot but be productive of material results.* 
3. By the application of the foregoing theory to the experi- 
ments on the electrical calamine, its elements will appear to be, 
Quartz - _ - i 
Calx of zinc ^ 
A small quantity of the calamine having escaped the action of 
the vitriolic acid, and remained undecomposed, will account for 
the slight excess in the weight of the quartz. 
4. The exhalation of these calamines at the blowpipe, and 
the flowers which they diffuse round them on the coal, are 
probably not to be attributed to a direct volatilization of them. 
It is more probable that they are the consequences of the dis- 
oxidation of the zinc calx, by the coal and the inflammable 
matter of the flame, its sublimation in a metallic state, and in- 
stantaneous recalcination. And this alternate reduction and 
combustion, may explain the peculiar phosphoric appearance 
exhibited by calces of zinc at the blowpipe. 
The apparent sublimation of the common flowers of zinc at 
the instant of their production, though totally unsublimable 
afterwards, is certainly likewise but a deceptious appearance. 
The reguline zinc, vaporized by the heat, rises from the crucible 
as a metallic gas, and is, while in this state, converted to a calx. 
The flame which attends the process is a proof of it ; for flame 
is a mass of vapour, ignited by the production of fire within itself. 
* It may be proper to say, that the experiments have been stated precisely as they 
turned out, and have not been in the least degree bent to the system.
