AN ADVERTISEMENT On the behalf of William Dockwra, Mercht. Concerning the PENNY-POST.  
WHereas the said Dockwra did above Nine Years since at his Sole Charge, first set up, that New and Useful Invention of the Penny-Post, so universally approved, and well known to be a Great and Public good. He was most unjustly deprived thereof, by the Power of the late King James, when Duke of York, under Colour of Law, and kept out of Possession in the late Reigns, without any ●anner of Reparation to this Day; as appears more fully by his Case lately Printed.  
Therefore finding himself obliged, for Vindication of his just rights, and in orderto the Reparation of his great damages; to make Address to the Parliament for Relief, he did accordingly exhibit his humble Petition, to the Honourable House of Commons, and upon Reading of the same there, it was Unanimously referred to the Committee of the whole House, for considering the Public Revenue.  
Soon after some Unnamed Person, did Print, and Disperse a Paper, which he called; An answer to Mr. Dockwras' Case concerning the Penny-Post: wherein, by citeing Part only of the Post-Office Staute, and asserting several untruths, and by frameing a Trufling Parallel, between the General and Penny Post (but leaving out the Ma●terial, and Essential Parts of the Practice, wherein they are utterly disagreeable and inconsistent) he put the whole Case in a False Light, and as much as in him lay, used his Talon towards the justifying of those Illegal and Arbitrary Proceedings, under which the said Dockwra with his Family of a Wife, and Eight Children, have been so many Years oppressed.  
The Design of which Paper, bespeaking the Author, to be a Man of as little Sense, as good Principles. The said Dockwra is well satisfied the present Governor of the General-Post Office, had no hand therein; as knowing his Abilities too great, and (believing his Ingenuity and Justice) to be far above thoughts so low, and attempts so malicious.  
Now whereas the said Dockwra, had prepared a Reply to that pretended Answer, which he had by him ready to wash off the Varnish of that Officious Undertaker, and solidly to Evince to the Parliament his Legal Title to this New Invention (never known or practised in the World before) and to expose the wicked many Thousand Pounds (just to bring the Penny-Post to Perfection) and having Dutifully attended the House of Commons to that End. The Parliament adjourned, before the Revenue was fettled; so that the said Dockwra's Case came not on to a Hearing this Session, for which Reason, he did not think sit to Print his Reply.  
But finding since the Adjournment of the Parliament, the same sort of Papers have been thrown into Coffeehouses and other Places, and Care taken, Industriously to spread false reports about Town, concerning the Issue of the said Dockwra's Petition, which may beget undue Impressions.  
The said Dockwra thinks it Incumbent upon him, to Advertise the Public hereby, that h●●● not met with any sort of Discouragement from the Parliament in his Application to them for Relief: ●●●on the contrary, hath found an Honourable and Universal Countenance therein, and doubts not ●●●t●●e next meeting of the Parliament) but that he shall receive from their great Wisdom and Justice, su● Generous Reparation for his Sufferings, and such due Reward for the Public Service he hath done h●● Country; as will be not only to his entire satisfaction, but to their Eternal Honour.
