Some of the observers were provided with wooden disks to cut off the light of the 
lower corona, so that the long extensions might be the better visible. Two of the 
disks were arranged to cover the corona to a distance of 3 feet from the moon’s limb, 
and one to a distance of 5 feet. 
Lieutenant Maetix, R.N., very kindly superintended the setting up of the disks. 
The disks themselves were of thin wood, about 5 inches in diameter, and were 
attached by iron rods to long spars standing vertically. The place for the eye was 
determined, in the first instance, with the aid of a theodolite and measuring tape, 
the altitude and azimuth of the sun at the time of eclipse, and the proper distance 
of the disk from the eye having been previously calculated. 
To guard against error, the pointers indicating the position of the eye were 
provided with horizontal and vertical movements. A horizontal bar was supported 
between two uprights about 18 inches apart, and from this was susjjended a piece of 
wood about 10 inches long, which could slide along it. A piece of brass, the end of 
which marked the place of the e 3 ^e, was free to slide up and down the vertical piece. 
Ten minutes before totality the disk observers were to be blindfolded, and, 
meanwhile, an amanuensis was to keep the pointer in the proper place; at the 
commencement of totality the observer wuuld take his place and dictate the 
directions and lengths in diameters of the most conspicuous streamers. 
II. Results Obtained. 
Forty^-five plates were exjiosed in the 6-inch prismatic camera, and three in the 
integrating spectroscope, but no images were obtained in consequence of the thick 
clouds. There was no opportunity of adjusting the 9-inch, so that the plates were 
not even exposed. 
Lord Graham secured during totality an excellent photograph with the 7h" X 5" 
camera, which showed that the sun was completely blotted out from view by the 
dense clouds at the time the exposure was made. 
The only other observations were those secured by the “ Volage” observers. These 
are appended. 
Meteorology [Temperatures). 
As already stated, six observers were told off to take thermometer readings at 
intervals of live minutes throughout the entire eclipse. Two observers were stationed 
at each thermometer, one to take the readings and another to note the times. 
The thermometer on Bras Havn was graduated on Fahrenheit’s scale and was fulR 
exposed. Those on Kid Island w^ere Centigrade thermometers, and they were 
supported at a height of 3 feet from the ground, at a distance of a foot from a piece 
of sail cloth, which shielded them from the direct rays of the sun. 
The readings observed are shown in the followino- table :—
