I was researching for that Mississippi Bubble, but found out the whole thing are much more complicated than we usually heard, it is actually the failure of the central bank. So I read some lengthy story of John Law in Adam Smith's lecture collections, starting from page 212
http://archive.org/details/lecturesonjustic00smituoftMr. Law, a Scotch merchant. He thought that national opulence consists in money, and that the value of gold and silver is arbitrary, and depends on constitution and agreement. He imagined that the idea of value might be brought to paper, and it preferred to money. If this could be done, he thought it would be a great convenience, as the government then might do what it pleased, raise armies, pay soldiers, and be at any expense whatever.
Mr. Law proposed his scheme to the Scotch parliament in 1701. It was rejected, and he went over to France, where his project was relished by the Duke of Orleans. In this book he agrees with the fore-mentioned writers that, the balance of trade being against a nation, it must soon be drained of its money. In order to turn the balance of trade in our favours, he proposed to the Scotch Parliament the following scheme :
As there was little gold or silver in this country he thought they might fall upon some other method of creating money, independent of it, to wit, by paper. On this account he proposed the erecting of a land bank at Edinburgh, in which it is to be observed, he falls into many blunders concerning tenures and the nature of property. At this bank they were to keep by them only twenty or thirty thousand pounds to answer small demands, and to give out notes for land. For two acres of arable land they were to issue out a note of equal value, and if any extraordinary demand was made upon them, they would pay so much of it in money, and so much in land. By this means in a very short time the whole land of Scotland would go from hand to hand, as a twenty-shilling note does.
As this project never was executed, it is hard to say what the consequence might have been ; it is, however, obviously liable to the following inconveniences. Taking the land rent of Scotland at five millions per annum, though it be much more, at twenty years purchase it amounts to an hundred millions; there would then be just so much currency in the country, and if one million was then necessary for circulation there would just be ninety-nine millions for no purpose, as none of it could go abroad ; they would not have been able to maintain one man more than formerly, as their food, clothes, and lodging would not have been increased, and every commodity would have risen to ninety-nine times its present value.

Acutally I disagree with Adam Smith here, John Law's reasoning is: As long as a money is backed by something valueable, it can hold its value. So even the money supply increased by 99 times because of the newly issued money, as long as they can be used to redeem valueable land, they will hold their value, will not cause inflation, because people still have to work to get those money, these money only belongs to previous land owners
It's clear that most of the central banks in the world operated in a very similar way of Law's experiment, but the interesting thing is why Law's plan failed, and how we could use his failure to forecast the future of today's financial situation
