sician, to whom he explained the title and nature of his little book. The doctor was transported with joy as soon as he heard it named, and immediately resolved to accompany Nicholas to Paris, that he might have a sight of it. The two set out together; the doctor on the way entertaining his companion with the history of his book, which, if the genuine book he thought it to be, from the description he had heard of it, was in the handwriting of Abraham himself, and had been in the possession of personages no less distinguished than Moses, Joshua, Solomon, and Esdras. It contained all the secrets of alchymy and of many other sciences, and was the most valuable book that had ever existed in this world. The doctor was himself no mean adept, and Nicholas profited greatly by his discourse, as in the garb of poor pilgrims they wended their way to Paris, convinced of their power to turn every old shovel in that capital into pure gold. But, unfortunately, when they reached Orleans, the doctor was taken dangerously ill. Nicholas watched by his bedside, and acted the double part of a physician and nurse to him; but he died after a few days, lamenting with his last breath that he had not lived long enough to see the precious volume. Nicholas rendered the last honours to his body; and with a sorrowful heart, and not one sou in his pocket, proceeded home to his wife Petronella. He immediately recommenced the study of his pictures; but for two whole years he was as far from understanding them as ever. At last, in the third year, a glimmer of light stole over his understanding. He recalled some expression of his friend the doctor, which had hitherto escaped his memory, and he found that all his previous experiments had been conducted on a wrong basis. He recommenced them now with renewed energy, and at the end of the year had the satisfaction to see all his toils rewarded. On the 13th January 1382, says Lenglet, he made a projection on mercury, and had some very excellent silver. On the 25th April following, he converted a large quantity of mercury into gold, and the great secret was his.
Nicholas was now about eighty years of age, and still a hale and stout old man. His friends say that by a simultaneous discovery of the elixir of life, he found means to keep death at a distance for another quarter of a century; and that he died in 1415, at the age of 116. In this interval he made immense quantities of gold, though to all outward appearance he was as poor as a mouse. At an early period of his changed fortune, he had, like a worthy man, taken counsel with his old wife Petronella, as to the best use he could make of his wealth. Petronella replied, that as unfortunately they had no children, the best thing he could do, was to build hospitals and endow churches. Nicholas thought so too, especially when he began to find
