science, of our special grace have granted and given leave to the same Edmund and Thomas, and to their servants, that they may work and try the aforesaid art and science lawfully and freely, without any hindrance of ours, or of our officers, whatsoever; any statute, act, ordinance, or provision made, ordained, or provided to the contrary notwithstanding. In witness whereof, &c., the King at Westminster, the 7th day of April" [1446.][23] Fuller leaves this curious document, which might fitly have been dated the _first_ instead of the 7th April, without a word of comment. The two knightly alchemists, doubtlessly imposing on themselves no less than on their royal patron, kept the king's expectation wound up to the highest pitch; and in the following year he actually informed his people that the happy hour was approaching when by means of "the stone" he "should be able to pay off his debts!"[24] It is scarcely necessary to add that the stone failed, and the king's debts must have remained unpaid, if his majesty had not pawned the revenue of his Duchy of Lancaster, to satisfy the demands of his clamorous creditors. Henry VI. was deposed by Edward IV. in March, 1461, and though he was nominally restored to the throne in October, 1470, he lost both crown and life in May, 1471, being found dead (most probably murdered) in the Tower on the evening or the morrow of the day on which Edward IV. entered London after his victory at Barnet. Such are some of the most notable facts in the practice of alchemy as connected with Lancashire. It will naturally be asked if alchemy is still practised in this county? We can only say, that if it be it is in very rare instances, and with the greatest secrecy. The more chemistry is known--and the extent to which it has been developed within the last twenty years is truly marvellous--the more completely it takes the ground from under the feet of a believer in alchemy. It is not like astrology, which accepts the facts of the true science of astronomy, and only draws false conclusions from true premisses. Alchemy could only have sprung up at a period when all the operations of the chemist's laboratory were of the most rude, imperfect, and blundering character; when the true bases of earths and minerals and metals were unknown; when what was called chemistry was without analysis, either quantitative or qualitative; before the law of definite proportions had been discovered; when, in short, chemistry was a groping in the dark without the help of any accurate weight or measure, or other knowledge of the countless substances which are now so extensively investigated, and so accurately described in the briefest formulas. A man, to become an alchemist in the nineteenth century, must study only the hermetical writings of past ages, shutting both eyes and ears to all the facts of modern chemistry. It is scarcely possible at this day to find such a combination of exploded learning and scientific ignorance.
