TOTAL ECLIPSE OF THE SUN, JANUAEY 22, 1898.

and concentric circles of one moon’s diameter each marked on it, and also the lines to 
divide the quadrants. One man, W. Paekhurst, A.B., used the ship’s long-distance 
telescope, and made a sketch of the whole corona. Another man also made a general 
drawing of the whole corona, using the naked eye only ; whilst, of the remaining 
eight, two sketched each quadrant.” 
Most of the sketches are excellent, but as they give no certain indications of 
details which are not shown in the photographs, it is not considered necessary to 
reproduce them. 
The 2t^-inch Equatorial Telescope. 
This telescope was used by Sir Norman Lockyer to observe the exact time of 
second and third contacts to give the signals “ Go ” and “ Over ” to the timekeepers. 
A diagonal eyepiece was employed, in which a silvered reflecting surface could be 
substituted for one of plane glass by the simple operation of sliding a frame 
containing these reflectors. For the first 50 seconds of totality he employed this 
instrument to minutely observe the structure of the rifts and streamers. In his 
absence the instrument was used by Assistant Engineer H. H. Willmore for the 
examination of the structure of the corona. Mr. Willmore took down the notes of 
Sir Norman Lockyer’s observations which are included in his report which 
follows :— 
“ From 127 seconds to 70 seconds Sir Norman observed through the telescojie, and 
I took the following notes at his dictation :—- 
“ ‘ Distinct structure at poles ; many lirilliant prominences ; much curvature ; long 
horn as in 1896 eclipse ; tracery at both poles quite exquisite ; four distinct 
streamers, one of three diameters.’ 
“At 70 seconds I took Sir Norman’s place. The corona appeared very different 
from anything I had seen in liooks, appearing more homogeneous and less well-defined 
in its various parts tlian any of the illustrations I had practised with. At the solar 
poles plume-like structures of great beauty were oliservable, intercepted by darker 
curved rifts. The inner corona was discernilfle from both the chromosphere and the 
outer corona, which latter appeared less liriglit. I particularly noticed a very bright 
prominence jutting out at the lower right-hand portion of the sun’s limb. The outer 
corona in its main features appeared to consist of four long conical streamers. I coidd 
discern no difference in the structures of these streamers. At 17 seconds Sir Norman 
again observed up till the expiration of totality. 
“For some 5 seconds after third contact the corona appeared to lose hardly any of 
its beauty or brilliance. Then it slowly faded, commencing fi'om its more remote 
portions towards the sun’s limb, this phenomena taking another 3 or 4 seconds.”
