+	abstract = {This paper describes a plan for making substitution weighings, applicable either to equal-arm balances or compound-lever scales, that has been developed in connection with the standardization of large weights at the Bureau of Standards. It has been prepared to meet a demand for an explanation of substitution weighing which has come from practical scale men in the field who have seen the plan in use by the representatives of the Bureau and who desire to adopt it. The description, however, will also be of interest and value to many workers in engineering and other laboratories who have A occasion to weigh large objects accurately.},
