The following pamphlet makes its appearance in conſequence of a Verdict given lately at Guildhall, London, on the trial of an action brought by Meſſrs. Boulton and Watt, (for an infringement of Mr. Watt’s patent for the Improvement of the Steam Engine) againſt Meſſrs. Hornblower and Maberly. The Verdict was for the Plaintiffs: But as the ſubject will probably undergo a further diſcuſſion, the author of theſe pages, who appeared on the Trial as a Witneſs for the Defendant, found himſelf called on to ſtate, what he conſiders as material to the Juſtice of the Caſe: And to ſhow that Mr. Watt’s Specification is not ſuch as to entitle him to the aſſiſtance of the laws of his Country in ſupport of his Monopoly.
