MR. J. N. LOOKYBR AND DR. SCHUSTER ON THE SOLAR ECLIPSE. 
Captain Waterhouse had intended to photograph the corona by means of the 
same instrument used by Colonel Tennant in 1871. 
Captain King and Mr. Chatterjee had volunteered to act as timekeepers. 
Professor Tacchini undertook all the observations to fix the latitude and longitude 
of the spot of observation, and also to determine the local time. Professor Tacchini 
had also watched any prominences during the days preceding the eclipse and on the 
morning of the eclipse. He writes : “ On the mornings of the 4th and 6th April 
the sun was almost entirely free from protuberances, which was in favour of the 
special object of the expedition to examine the fight of the corona. On the morning 
of the 6th at the angle 107° I saw bright flames which seemed to indicate an eruption, 
but after having finished the examination of the limb all had disappeared, and with 
the narrow slit I saw no reversed fines beyond the ordinary ones of hydrogen, and I 
also obtained the same result in other parts of the limb.” 
Considering the complete state of preparation, it is a matter of great regret that the 
observations were prevented by the state of the weather. 
X. SUMMARY OP RESULTS. 
In conclusion we give a summary of the results which we have obtained : — 
1. The fight given out by the prominences when analysed by a prism gives in the 
less refrangible part of the photographic spectrum two fines, which are most likely due 
to the hydrogen fines H/3 and Hy. 
2. The strongest protuberance fine lies in the ultra-violet. The actinic effect of the 
protuberances must chiefly be due to this fine. 
3. The upper parts of the corona give a photographic spectrum which is homo- 
geneous and apparently due to the hydrogen fine near G. 
4. The lower parts of the corona send out a strong continuous spectrum, extending 
into the ultra-violet to a wave length 3530, that is, beyond N, and reaching to a height 
of about 3' from the sun. 
5. Photographs of the corona show that the extent of the corona rapidly increases 
with increasing times of exposure. The corona has, therefore, no definite outline. 
6. We have been able to confirm the results obtained by Mr. Stone that the corona 
is symmetrical round the axis, the greatest extent being in the direction of the sun’s 
equator. 
7. The corona presents a striking resemblance to that observed just one year before 
by Mr. Stone at the Cape of Good Hope.
