I cannot venture in a single article to exhaust the suggestions in the Century, and must refer my reader to the volume himself, assuring him that he will there find many curious hints, several of which have, since its publication, been very practically realized. It is worth noting, however, that the author seems to have fully anticipated a very remarkable modern invention, in declaring that 'a woman even may with her delicate hand, vary the ways of coming to open a lock ten millions of times, beyond the knowledge of the smith that made it, or of me who invented it.' From this, as I have already suggested, it appears that he had, far in advance of his age, mastered a very great principle in mechanics; and as he appears to have understood, in theory at least, several others, it is no more than justice to rank him far above those mere charlatans of science, and hunters for marvels by means of isolated observation and experiment, with whom many would place him. That the 'Century' contains much which would be very discreditable to any man of science at the present day, is very true. Perpetual motion, perfect aerostation, devices for idle tricks and mere thaumaturgy, appear in company with schemes to take unfair advantages at card playing, and for the construction of false dice boxes--of which latter it is indignantly observed by honest Partington, that, there are few who profess the science of cheating at cards or dice, or to be encouragers of those who do; and it may fairly be conceded that there are not two periods in our regal annals, in which this detestable meanness had become fashionable enough to sanction a nobleman in inscribing to a king and his parliament a method by which it might be advantageously effected! We may, however, believe that a second period has at the present dawned over England, not much inferior as regards 'detestable meanness,' to that of Charles the Second. A recent transaction has shown that noblemen and their friends in the year 1862, are not above ascertaining from Johnson's Dictionary, the obsolete spelling of a word, such as _rain_-deer, betting a hundred pounds with an American as to its true orthography, and agreeing with him to abide by Johnson's authority; a piece of swindling quite as detestable in its meanness as the using of loaded dice. Neither can I see that the conduct of a majority of the British people, in fomenting Abolition for many years, and then giving her aid and countenance to our Southern rebels, on the flimsy, and, at best, brazenly selfish plea of the Morrill Tariff, is less detestable or less mean. We may regret to see a vice in individuals tolerated in high places; but when the blackest inconsistency, and the most contemptible avarice are elevated by a Christian nation into principles of conduct toward another nation struggling to free the oppressed, we may well doubt whether another period has not approached in England, over which
