SOLAR ECLIPSE OP AUGUST 29, 1886. 
:3G1 
At the end of the observation I am certain that B was considerably longer tlian A, 
though, as I said before, they appeared to be exactly similar at first. I should be 
inclined to attribute this to the fact that the Sun was altering a little in azimutli, 
and towards the end of the observation I had given all the correction that the 
apparatus admitted of, and therefore the Sun got nearer to the side of the disk. 
I found that the Sun altered in altitude so rapidly that it was difficult to keep 
pace with it with the rough arrangement for altering the elevation of the eyepiece; 
a small rack and pinion would have been a great boon. 
A better arrangement for making coi'rection in azimuth and a longer range would 
be an advantage. 
The cross-piece, inch wide, interfered with the observation; a thin metal rod 
or stout wire would have been better. 
I observed with the disk until the last moments of totality, and only just looked 
off in time to see the burst of bright light at the second internal contact. I at once 
made the (original) sketch which I send, and saw nothing of any other phenomena, 
as, two minutes after, everything was obscured in clouds and we were in a drenching 
rain. 
I had the tides both before and after the eclipse measured, and found the rise and 
fall was normal, 18 inches.

Notes descriptive of Drawcvg (Plate 11) by Lieutenant J. Masterman. 
A and B.—Very distinct, especially B. They each formed an angle of 45° with the vertical. 
B appeared to increase in length, not in brilliance ; A did not. 
G-—Distinct, but small. I could not detect any sign of C above the batten, though, if the upper edge 
had been inclined to tbe horizontal at the same angle as the lower edge was, I think 1 must have done so. 
D and E.—Very faint indeed, merging into the luminosity which was faintly apparent between all the 
shoots of light; but, faint as this luminosity was, it had a distinct definition, which bad tbe appearance 
of going about the points of the shoots. 
Copy of sketch of the phenomenon as observed by me with one of the disks mounted on the roof of a 
hut. 
Dimensions:—Disk, 9 inches diameter; cross batten, 1| inch; upiight battens 1 inch, length 
2 feet 10| inches.
