The weather on the day of the eclipse was disappointing. For two 

 hours before totality the entire sky was covered by light, though un- 

 broken, clouds. At the time of totality, however, the clouds in the im- 

 mediate vicinity of the sun appeared to break away, and the inner corona 

 shone through light, drifting clouds. No clear sky was visible, however, 

 within several degrees of the sun, neither Mercury nor Regulus could be 

 seen from this station. During the morning a moderate wind prevailed, 

 the general direction being W. N. W. The first contact was, neglecting 

 seconds, at 11:41. The weather conditions during the eclipse, as observed 

 and recorded by Mr. Thompson were as follows:

Considering the weather conditions, our plates are very satisfactory. 

 The shortest exposure, showing the prominences, suffered very little. 

 The very bright group on the eastern edge of the sun is particularly well 

 defined, and the negatives made of it with the long-focus camera hold a 

 wealth of detail. The longer short exposures with the long-focus as well 

 as the short-focus cameras show considerable coronoe detail, while the 

 longest exposures have that part of the corona uncovered by the clouds 

 much overexposed, while the clouds made it impossible to register any 

 extended streamers. All the plates lack the definiteness that would have
