PLATE XX.
Is a true Plan and Combination of the principal Stars that form the Persedes, in which other Observations may be made in a different Part of the Heavens, and perhaps with an Opportunity of being still more exact, the Areas of these Triangles, particularly that of Θ I K, and those of ρ and δ, being much less than the former, where the least Alteration possible must render them sensibly distorted. But here it must be considered, that the real Motion of the Stars, as well as their apparent, may be, and in all Likelihood, is extreamly slow, for the most minute, visible, local Motion, will answer all the Purposes we know in Nature, and the greatest seems to be that of the projectile, or centrifugal Force, which not only preserves them in their Orbits, but prevents them from rushing all together, by the common universal Law of Gravity, which otherwise, as a finite Distribution of either regular or irregular Bodies, they must at length do by Necessity.

Plate XX.
I must now inform you, that the above Observations were compleated in the Autumn Season, 1747, and were taken by myself; the Letters A, T, in Plate XIX, and the W in the XXth, as you may see, having a very near Resemblance, or Similitude, to the Order these Stars are found to be in, together with the Greek Alphabet, I judged necessary, by way of Asterism and Nomenclatura, in case such should be wanted, as Data in future Discoveries.
I come now to the principal Point in Question, which is to find a regular Disposition of the Stars amongst themselves, which will naturally solve both their general and particular Phænomena, especially the Nebula and Milky Way.
I am now, &c.
