make use of new practices, which themselves have not throughly tried, and which length of time hath not vindicated from latent inconveniences; so as when a new Invention is first propounded, in the beginning every man objects, and the poor Inventor runs the Gantloop of all petulent wits; every man finding his several flaw, no man approving it, unless mended according to his own advice: Now not one of an hundred out-lives this torture, and those that do, are at length so changed by the various contrivances of others, that not any one man can pretend to the Invention of the whole, nor well agree about their respective shares in the parts. And moreover, this commonly is so long a doing, that the poor Inventor is either dead, or disabled by the debts contracted to pursue his design; and withall railed upon as a Projector, or worse, by those who joyned their money in partnership with his wit; so as the said Inventor and his pretences are wholly lost and vanisht.
Secondly, a Monopoly may be of real use for a time, viz. at the first introducing of a new Manufacture, wherein is much nicety to make it well, and which the generality of men cannot judge of as to the performance. As for example; suppose there were some most approved Medicament which one certain man could make most exactly well, although several others could also make the same less perfectly: in this case this same chief Artist may be allowed a Monopoly for a time, viz. |56| until others have had experience enough under him, how to make the Medicament as well as himself. First, because the world may not have the Medicament variously made, when as they can neither discern the difference by their senses, nor judge of the effects thereof à posteriori, by their reasons. Secondly, because others may be fully instructed by him that can best do it; and thirdly, because he may have a reward for such his communications: But forasmuch as by Monopolies of this kinde, great Leavies are seldom made, they are scarce pertinent to our design.
Offices instituted by the State of Fees of their own appointment, are of parallel nature to Monopolies; the one relating to actions and employments as the other to things,
