About the year 1590, Mr. Edward Wright, an Englishman, discovered the true principles upon which such a chart should be constructed; and communicated the same to one Jodocus Hondius, an engraver, who, contrary to his honest faith and engagement, published the same as his own invention: This occasioned Mr. Wright, in the year 1599, to exhibit his method of construction, in his book, intitled, _Correction of Errors in Navigation_; in the preface of which book may be seen his charge and proof against Hondius; and also how far Mercator has any right to share in the honour due for this great improvement in geography and navigation. Blundevill, in his Exercises, page 327, published anno 1594, gives a table of meridional parts answering to even degrees, from 1° to 80° of latitude, with the sketch of a chart constructed therefrom; but this table he acknowledged to have received from Mr. Wright, in the following words, page 326, _viz._ “In the mean time to reform the saide faults,” (in the plane chart) “Mercator hath in his universal chard or mappe made the spaces of the parallels of latitude to bee wider everie one than other from the equinoctial towards either of the poles, by what rule I know not, unless it be by such a table as my friend Maister Wright of Caius-college in Cambridge at my request sent me (I thank him) not long since for that purpose, which table with his consent, I have plainlie set down,” _&c._ About the year 1720, a globular chart was published, said to be constructed by Mr. Henry Wilson; the errors in which were obviated by Mr. Thomas Haselden, in a letter to Dr. Halley; who at the same time exhibited a new scale, whereby distances on a given course may be measured, or laid off, at one extent of the compasses, on Wright’s projection; and was intended to render the same as easy in practice as the plane chart. The above chart was published in opposition to Mr. Wright’s, which that author charged with imperfections and errors, and that it represented places bigger than they are upon the globe. It is true, the surface is apparently enlarged; but the position of places, in respect to one another, are in no wise distorted; and it may be asserted, with the same parity of reason, that the lines of sines, tangents, and secants, are false, because the degrees of the circle, which are equal among themselves, are thereupon represented unequal. Yet if a map or chart was so constructed, as to shew the situation and true extent of countries, _&c. primâ facie_ (if I may be allowed the expression), and yet retain all the properties, uses, and simplicity, of Wright’s construction, it would be a truly great improvement; but this seems to be impossible. The method exhibited by the Rev. Mr. Murdoch, in his paper, read before the Royal Society on the 9th of February last, shews the situation of places, and seems better calculated for determining superficial and linear measures, than any other that has occurred to me.
