Usage examples of results.

Knowing that only certain bodies are present, it is evident that the number of separations can be reduced, and that simple methods can be devised for arriving at the results sought for.

Unfortunately, using both methods and accepting the difference in the results as a measure of the quantity of zinc present, or at any rate of the zinc present as cyanide, is not satisfactory.

By this means they will, at the same time, acquire the skill necessary for performing an assay and a confidence in their results based upon work under different conditions.

The calculations should be done on scrap-paper, and should not be entered, although, of course, detail enough must be shown to enable the results to be recalculated.

Gravimetric and Volumetric, in the former of which the final results are weighed, whilst in the latter they are measured.

Whether a process yields proportional results, or not, will be seen from a series of standardisings.

Having obtained these, the results should be arranged as in the table, placing the quantities of metal used in the order of weight in the first column, the volumes measured in the second, and the standards calculated in the third.

If the results are proportional, these standards will vary more or less, according to the delicacy of the process, but there will be no apparent order in the variation.

All processes yield fairly proportional results if the quantities vary within narrow limits.

Treated in the same way the oxide of zinc, sulphuric oxide and water give as results 0.

For practical purposes it should mean the first of these, for in the actual experiments the water and the substance are compared at the same temperature, and it is well to give the statement of results without any superfluous calculation.

The results will differ somewhat with the dryness and quality of the flour, etc.

These facts serve to explain some apparently irregular results got in practice.

The results of two assays, after deducting for the silver in the litharge used, were 3.

With the help of a table of cubes the whole calculation for 25 or 30 divisions may be made in half an hour, and the results preserved in the form of a table will simplify all future work.
