Goodyear had almost mastered the secret of vulcanizing rubber. He does not appear, however, to have known the true nature of aqua fortis, and called his process the "curing" of India-rubber by the use of that acid. The "cured" India-rubber was subjected to many tests, and passed through them successfully, thus demonstrating its adaptability to many important uses. Mr.
EXPERIMENT IN CONSORT, Touching Whiteness & Blackness. Having promis'd in the 114, and 115. N. First, That it is not so necessary to employ either Aqua Fortis or Spirit of Urine about this Experiment, but that we have made it with other liquors instead of these, of which perhaps more elsewhere.
To apply these results to the Saturnian verses extant, let us select a few examples: "Gnaivod patre prognatus | fortis vir sapiensque." patre or patred retains its length by position, i.e. its metrical accent, against the natural accent patre. In the case of syllables on which the ictus does not fall the quantity and accent are indifferent.
No one seemed to think of doubting that the prediction must eventually come true, but it was hardly likely to be verified in time to convert Tomaso into a serious rival to Felipe Fortis. There were assuredly no fortunes to be made out of the half-ruined mill. The trade had left that for ever. There was no money in the whole valley, and Tomaso did not seem disposed to go and seek it elsewhere.
Letters written with a solution of gold, silver, copper, tin, or mercury dissolved in aqua fortis, or simpler still of iron or lead in vinegar, with water added until the liquor does not stain white paper, will remain invisible for two or three months if kept in the dark; but on exposure for some hours to the open air will gradually acquire color, or will do so instantly on being held before the fire.
Upon one occasion, while bronzing a piece of rubber cloth, he applied aqua fortis to it for the purpose of removing the bronze from a certain part. It took away the bronze as he had designed, but it also discolored the cloth to such a degree that he supposed it ruined, and threw it away.

Translated from the French, 8vo. Rhodes and Candia are most particularly described in this volume, islands of which we previously had meagre accounts. Fortis' Travels in Dalmatia. 4to. The geology, natural history, and antiquities of this country, with curious and instructive notices on the singular races which inhabit it, form the subject of this volume, which is translated from the Italian.
Dazzled by the strong and sudden glare, Del Fortis recoiled, and still holding the phial of poison in his hand, stumbled back against the half-fainting form of the poor crazed creature he had been terrorising, as a dozen armed men silently entered the dungeon and ranged themselves in order, six on one side and six on the other, while, in their midst one man advanced, throwing back his dark military cloak as he came, and displaying a mass of jewelled orders and insignia on his brilliant uniform.
He ``accordingly bought seven: viz., aqua fortis, white arsenic, mercury, powder of diamonds, lapis costitus, great spiders, cantharides. Franklin's evidence is a palpable tissue of lies, full of statements that contradict each other, but it is likely enough, judging from facts elicited elsewhere, that his list of poisons is accurate.
