Not illustrated. 1895 Excerpt: ...limb, of four cavernous depths, at which the more foreshortened side would contract to a line, and appends the corresponding apparent widths of the opposite side. His figures for spots of the first and second classes, in the order of decreasing depths, are: --at bo ' from the limb, the inward side of penumbra vanishing and outer side width 8""58; at 30" distance, inward side vanishing, outer side width 6" 02.t Now of our 47 cases favourable to Wilson the best is perhaps the one near the eastern limb on 1886 May 21. It is a good spot with a good history, and judging by its size and darkness it should be ranked at least in Wilson's second class. It should therefore, when at 30" from the limb, have lost the inward side of its penumbra: it was just within 30" distance, and showed the Phil. Trans., anno 1783, vol. lxxiii. t The great spot of November 1769, which first drew Dr. Wilson's attention to the subject, was estimated, from his observations at the return of the spot in December, to have been at this limiting position, at 90'' from the eastern limb. inward side a little more than half the width of the outer side. It may well be doubted whether Dr. Wilson would have formulated his cavernous theory upon these cases, which would indicate declivities too small to be worthy of notice. There is, however, one case which has no exception to its evidence, and which but for the smallness of the spot would take precedence of the one just mentioned. It crossed the Sun's disc in the last half of July 1884. It appears on the drawings at 35" from the eastern limb on the 17 th, and at 2' on the 18th, quite clearly for Wilson. On the 19th the umbra was central at 3' 30" distance. On the 20th the umbra was broken on the eastern side; b.
