And now my character is placed above all suspicion of fraud by authentick documents, I will make bold, at last, to pull off the mask, and declare sincerely the true motive that induced me to interpolate a few lines into some of the authors quoted by me in my Essay on Milton, which was this:  Knowing the prepossession in favour of Milton, how deeply it was rooted in many, I was willing to make trial, if the partial admirers of that author would admit a translation of his own words to pass for his sense, or exhibit his meaning; which I thought they would not:  nor was I mistaken in my conjecture, forasmuch as several gentlemen, seemingly persons of judgment and learning, assured me, they humbly conceived I had not proved my point, and that Milton might have written as he has done, supposing he had never seen these authors, or they had never existed.  Such is the force of prejudice!  This exactly confirms the judicious observation of the excellent moralist and poet: 

  Pravo favore labi mortales solent;
  Et pro judicio dum stant erroris sui,
  Ad poenitendum rebus manifestis agi.

For, had I designed, as the vindicator of Milton supposes, to impose a trick on the publick, and procure credit to my assertions by an imposture, I would never have drawn lines from Hog’s translation of Milton, a book common at every sale, I had almost said, at every stall, nor ascribed them to authors so easily attained:  I would have gone another way to work, by translating forty or fifty lines, and assigning them to an author, whose works possibly might not be found till the world expire at the general conflagration.  My imposing, therefore, on the publick in general, instead of a few obstinate persons, for whose sake alone the stratagem was designed, is the only thing culpable in my conduct, for which again I most humbly ask pardon:  and that this, and this only, was, as no other could be, my design, no one, I think, can doubt, from the account I have just now given; and whether that was so criminal, as it has been represented, I shall leave every impartial mind to determine.

AN ACCOUNT OF AN ATTEMPT TO ASCERTAIN THE LONGITUDE[1].

FIRST PRINTED IN THE YEAR 1755.

It is well known to seamen and philosophers, that, after the numerous improvements produced by the extensive commerce of the later ages, the great defect in the art of sailing is ignorance of longitude, or of the distance to which the ship has passed eastward or westward, from any given meridian.

That navigation might be at length set free from this uncertainty, the legislative power of this kingdom incited the industry of searchers into nature, by a large reward proposed to him who should show a practicable method of finding the longitude at sea; and proportionable recompenses to those, who, though they should not fully attain this great end, might yet make such advances and discoveries as should facilitate the work to those that might succeed them.
