upon A: S. C(oolidge), and another. 26, f corner decidedly 

 darker than p, at times almost black; Fig. 2 : B. II. /much 

 stronger and blacker than p ; p projects very little ; ball seems 

 to project upon A, which is a shade darker between the two 

 corners : B. I. Mouse-coloured shading on A from horn to 

 horn; ball less projecting upon A; p shadow less dark and 

 visible ; /increasing every way; black : S. C. — 1855, Jan. 25, 

 a nearly black spot in the p shadow [now much smaller than 

 /] : B. II, S. C. Mouse-coloured shading of Dec. 26 not now 

 to be seen: S. C. Feb. 28, p shadow scarcely discernible; / 

 angular on A, encroaching on Ball's div., and "giving to the 

 outline of that part seen on ring A and division of rings the 

 appearance of a roof with broad projecting eaves :" S. C. 

 Corner juts over upon division (but not on rings) like eaves of 

 a roof: B. II. March 29, s/linib of ball straight in front of 

 shadow; s sliced off; vision not very good: S. C. Spring, 

 shadow across B straight or concave ; different observers and 

 artists differed as to form : Secchi. Nov. 9, shadow above S. 

 limb " much less dark on the upper and right hand portions 

 than on the left hand : 3; B. II. 13, p> shadow straight; a faint 

 shadow /, (Fig. 3) : S. C. 26, both shadows concave near 

 division, / most so ; p. straight everywhere else, even on dusky 

 ring ; adjacent limb also straight and distorted from inferior 

 definition: S. C. [Ball overlapping A a little: S. C. 27, on 

 the contrary, evidently not reaching division : Lassell. This 

 seems to be the greatest amount of opening.] Dec. 6, both 

 concave ; / very narrow, and not so dark as p, which alone is 

 seen on dusky ring, and seems to have a penumbra along outer 

 edge; S. limb not distorted; encroachment of ball on middle 

 of shadows may cause apparent concavity: S. C. 6, 12, a 

 kind of " cornering :" Lassell. — 1856, Jan 8, 10, outline re- 

 versed with low powers, yet illusion suspected [much as Fig. 

 2, but each side equally black and blunted] ; " I am quite 

 unable to imagine any section for the bright ring (compatible 

 with its ascertained thinness) that would give such an outline 

 to the shadow •/' 22, 23, shadow convex all round S. limb, 

 but with 2 actors where it crosses Ball's div. ; exact form could 

 not be made out, but rather triangular; seen distinctly crossing 

 division, which was much paler than shadow, brown instead of 

 black, and from form of shadow would seem below level of 

 rings: Jacob (Madras). Feb. 4, shadow has not the reversed 

 beak, and seems to extend upon A: Secchi. 28, outline 

 changed since Dec. 6 ; more regular, and a slight projection 

 upon A, but still corners at division; p faint and very small ; 

 /plainly seen on C : B. II. March 1 1-, trace of p shadow at a, 

 (Fig. 5) ; at narrowest part, r J, f is wider than C at minor 

 axis; its "roof" overlaps division, and is projected on A ; it
