From this port foreign merchandise found its way duty free into the Spanish provinces of Buenos Aires, Tucuman and Paraguay, and even into the interior of Peru.
They urged, among other things, due enforcement of the liquor law, more police protection, the abolition of the dynamite concession, and that foodstuffs should be duty free.
The great importance of alcohol in the arts has necessitated the introduction of a duty-free product which is suitable for most industrial purposes, and at the same time is perfectly unfit for beverages or internal application.
From 1858 to 1861 methylated spirit was duty-free when it was required for manufacturing processes, and the methylation or "denaturizing" was carried out in accordance with a prescribed process.
During the next three decades (1861-1891) the law was extended, and methylated spirit was duty-free for all purposes except for use as beverages and internal medicinal applications.
