362 REV. S. J. PERRY ON THE TOTAL SOLAR ECLIPSE OF AUGUST 29, 1886. 
Drawing by Mr. F. W. Osburn, R.N., of H.M.S. “ Bullfrog.” 
Horizontal distance from eyepiece to disk, 26 feet 10 indies ; heiglit above level of ejebole, 9 feet 
4 inches; diameter of disk, 9 inches; angular diameter, 1° 31'; breadth of upright batten, 1 inch; 
breadth of cross batten, 1^ inch; height of disk above ridgeway of roof, 2 feet 10^ inches. 
Note. —At the commencement of totality, when my eyes were first unbandaged, 1 found, on looking 
through the eyepiece, that the eclipsed Sun was about 4 diameters above the disk, aud some time was 
wasted in shifting tlie eyepiece down as far as it would go, when the Sun and corona w'cre just covered 
by the disk ; but before totality was over, the corona was again visible over the top of the disk. 
Marked a .—Around three parts of the disk there appeared a band of blight light, sharply defined and 
irregular in .shape, its broadest part on the right, and gradually diminishing until, at the left lower 
corner, it ceased altogether. 
Marked h .—Entirely surrounding the disk I observed an irregularly shaped field of very faint light, 
standing out at its widest part nearly 1 diameter beyond the disk. 
Into the field above mentioned I observed two very faint rays extending, one towards the zenith (but 
so faint as to be hardly disceiaiible), and the other to the right of the disk (which I saw more clearly), 
on each side of the horizontal support; these rays arc marked respectively c and d. They appeared 
about equal in length, i.e., 1 diameter of the disk. 
Francis W. Osburn.
