During eighteenth century England the Excise Department was at the vanguard of negotiating the criteria and parameters of what I call "practical objectivity", namely, putting objectivity into administrative practice. This frequently required both the space of production and the actual product to be reconfigured to meet the criteria of the excise's form of measurement. As this essay shows this was a contested, mutable and ambiguous process. Within this context ultimate agreement over objectivity was administratively rather than philosophically driven.
