Compendiosa demostracion de los crecidos adelantamientos, que pudiera lograr la Real Hacienda de su Magestad mediante la rebaja en el precio del azogue, que se consume para el laborio de las minas de este Reyno... Mexico: widow of José Bernardo de Hogal, 1743

A treatise on the price of mercury and its effect on the production of silver in the mines of New Spain, written by the chief mining agent for the Spanish Crown. Fabry sought to demonstrate that a lower price for mercury (subject to a government monopoly and essential for producing silver) would increase the yields from silver mining.
