VALIDITY OF THE PATENT ARGUED.

buck's instance, to perform the condensation without injection. He had a predilection for the wheel engine, and much time and labour were spent on it, while he was uncertain whether he should bring this, or the reciprocating engine, first to the market. He had experience to acquire in great works, and in the practice of several trades employed in such constructions. He had workmen to instruct, and to form; and to keep with him, after they had acquired from him a little knowledge, and were worth bribing away from him. But the chief cause of the delay was that indelible trait in Mr. Watt's character, that every new thing that came into his hands became a subject of serious and systematic study, and terminated in some branch of science. How rarely do we meet with such a conjunction of science and art,-how precious when it is found;-how much then does it deserve to be cherished! What advantages have been derived within these twenty years from this fortunate union ;-how much then does it become our courts to encourage and support it against the unprincipled attacks of ignorant and greedy plagiarists, who would deceive our men of property, ruin them by expensive projects. which terminate in disappointment, and thus discourage those who alone can by their capital give any effectual aid to the energy and genius of this country! We boast of our Newton, and place him at the head of our philosophers ;-our Boulton and Watt want only justice, and all Europe will place them at the head of our artists.”

The originality of the invention, and its great importance to the public, were at once established by the plaintiffs; and, indeed, were admitted by the defendants. The very multitude of the infringers bore testimony to the value of the discovery; their occasional construction of tolerable engines on the new principle, proved the sufficiency of the specification; and their audacity was in proportion to the despair they felt of being able to rival, by honest means, the success of the inventor. The whole weight of the evidence was justly held to be in favour of the plaintiffs, on whose side were called men of the highest order of intelligence

and of the greatest celebrity in physical science, as well as in the various departments of the arts:-such as De Luc, Herschel, Ramsden, Robison, Cumming, Southern, and others, most of whom, as has already been mentioned, had also given evidence in the previous case against Bull.

Among the host of opponents who, having in the first place themselves infringed the patent, were disinterestedly desirous, for the benefit of the public, that its validity should be overthrown, one of the most forward, pertinacious, and loud, was Joseph Bramah. This person, very well known for his ingenuity in mechanical improvements in locks, his hydraulic press, and other useful contrivances, attended as a witness on behalf of the defendants in 1796; but having on that occasion been cut short, by the Judge, in an endeavour to lay before the Court what he calls "a few remarks," (they extend to ninety-one printed pages!),he at last delivered them to the public in the form of a letter to the Chief Justice, remonstrating against the verdict which had been unhesitatingly found for the plaintiffs. In the outset of this epistle, Bramah states that he was, at the trial, “much incapacitated by those alkalescent and morbific exhalations, ever a consequence of large and close assemblies;" and the abrupt judicial syncope of his intended evidence he attributes, (no doubt justly enough,) to the attention of the Court having "become flaccid through fatigue."

The specification of the separate condenser generally, is, this excelling sage informs us, a "very abstruse and ambiguous concern:" and that of the steam-wheel, "a complete jumble of incoherent, unconnected, absurd, and indigested ideas; so blended and coagulated with mystery, ambiguity, and impossibility in practice, that it is a disgrace to the writer, and would undoubtedly ruin any mechanic who might attempt to analyse it."

The principle of working engines by the alternate expansion and contraction of steam, (the expansive principle added to the separate condensation,) he introduces thus :-"And behold! what does he," [Mr. Watt] ("by way of misleading) but propose what

every man of chemical science must reject, viz., to work engines by the partial expansion and condensation of steam!"

Bramah offers it as "a condensation of his own ideas diffused through his letters," that "all kinds of condensers, and even eduction-pipes, on the principle of Watt's engines, impede the working of the engine;" and "thinks that it must be obvious to every one, as it had ever been to him, that Mr. Watt had really invented nothing but what would do more mischief than good to the public."

It was in the vexation caused by the multifarious piracies, of which Bramah's was one, that Mr. Watt was tempted, "in the anguish of his mind," almost to " curse his inventions; declare that "there is nothing more foolish than inventing; and that "nine-tenths of mankind are knaves, and a large proportion of the remaining one-tenth, fools." From an equally temporary cause alone, let us hope, also proceeded his evil opinion of some of the gentlemen belonging to a certain branch of the legal profession, whom he called "the anthropophagi of London;" and of whom he said, that "if all the counties in England would join in petitioning Parliament to make it high treason for any of the tribe to be found in the realm, it would be the wisest thing they ever did!”* It was certainly unfortunate for the reputation of Bramah, himself a self-taught inventor of great mechanical ingenuity, that he should have been led, by whatever motive, into systematic and grudging opposition,-(which was also, happily, unsuccessful,)-to the grand and prolific discoveries of Watt.

The verdict of the jury, on occasion of both of the trials, having gone with the stream of testimony which flowed so overwhelmingly in favour of the patentees, the judgment of the Court finally established the legal validity of the letters patent, and effectually vindicated the justice of all the claims that Boulton and Watt had made. That decision has always been viewed as one of great importance to the law of patents in this kingdom,

and was, of course, productive of momentous consequences in a pecuniary point of view to the patentees; as, besides heavy damages and costs being recovered from the actual defendants, the remainder of the horde of delinquents were thereby, at last, awed into subjection, and compelled to disgorge a large portion of their illegal gains. In judgment on the vanquished, however, mercy was not forgotten by the victors; and the terms of settlement insisted on were, it is believed, generally satisfactory to all parties. Mr. Watt used, long afterwards, to call the specifications his old and well-tried friends.

WITH the year 1800 came the expiration of the privilege of the patent of 1769, as extended by the statute of 1775; and also the dissolution of the orignal copartnership of Messrs. Boulton and Watt, of five-and-twenty years' duration; a term which had been fixed with a prospective reference to the duration of the privilege, and which, having at its commencement found the partners active and strong,

"In mezzo del cammin' di nostra vita,"

left them, at its close, far advanced on that toilsome journey, and disposed to resign the cares and fatigues of business to other and younger hands. Those two friendly associates, who might well be termed the fathers of the modern steam-engine, did not, therefore, in their own persons renew the contract which they had in earlier and more eventful times so strenuously, so successfully, and so happily fulfilled. But their respective shares in the concorn were readily adopted, as the basis of a new contract, by their sons, Messrs. James Watt, jun., Matthew Robinson Boulton, and Gregory Watt; all distinguished by great talents, and already to a considerable extent initiated in the conduct of the business, by
