It very often happens that it is required to know the weight of a piece of metal which, from the irregularity of its shape, the absence of the proper tables, or some other reason makes the necessary calculation either impossible or at best a long and tedious operation.
It will take but little consideration to see how the principle of the Planimeter just mentioned can be utilized in a case of this kind by so adjusting the instrument as to cause it to record the desired weight of the metal when the tracer has been passed about its plotted boundary.
