216 Proceedings of the Asiatic Society. [Sept. 



commenced. I supposed myself to be about 9 minutes north of the 

 central line of eclipse, and calculated that I should have a period of to- 

 tality equal to 5 minutes and a half. 



I observed with a 120-power telescope by Dollond, through a 

 double glass of red and brown. The power was sufficient to show the 

 broken outline of the moon, and as totality approached, the bright 

 lights on the high grounds in the moon were shown most beautifully 

 on the illuminated edge of the moon's disc. 



Interested by the account given in Major Tennant's paper as read by 

 him before the Asiatic Society at Calcutta, regarding the observations 

 made at Ragusa in March 1867, by Ensign Kiha of the Austrian navy 

 through a cobalt blue glass, I tried to observe through a glass of 

 bright Prussian blue ; but when only ten minutes from totality, I found 

 it impossible to look at the sun through such a pale colour. So it is 

 inexplicable to me, how Ensign Kiha was able to look at the sun 

 through a brighter colour under less favorable circumstances. During 

 totality, I looked for 3 minutes through the blue glass, and thought 

 the appearance of the corona and flames to be then infinitely more 

 beautiful than when seen through the darker glass, or by the naked 

 eye. 



During totality, the mercury of the thermometer in the open air and 

 attached to the telescope tripod fell to 83.5 degrees being a fall of twelve 

 and a half degrees. A minimum thermometer, in the verandah of Colonel 

 Winscomb's house, fell to 82°. Unfortunately the reading of the maxi- 

 mum thermometer placed in the same situation, could not be depended 

 upon. 



There was no appreciable change on an Aneroid Barometer during 

 the progress of the eclipse. 



With reference to my remarks on the light during totality, I will 

 record a few of the facts from which I made my comparison. 



First, I noticed hills left and right of the flooded valley of the 

 Kistna at distances of three and four miles. They were discernible 

 during the totality. 



Secondly, A house painted with a light colour, overlooking the town 

 of Bezwarra, was situated on the side of a hill distant about 2000 yards 

 from my station. Two or three hundred feet higher up, on the face of 

 the same hills, I noticed a precipice of dark rock. Both the light 

 and dark objects remained visible.
