mains open; there is not a sufficient number of accordant 
results free from suspicion, either on account of unfavourable 
sky or inaccuracy of instruments. 
Professor W. G. ApAms then exhibited photographs by the 
oxyhydrogen lime-light. 
The photographs shewed the corona as seen from Sicily, 
having been taken at Syracuse by Mr Brothers. In exhibiting 
the photographs, Professor Adams called attention to various 
points of interest in them. 
There were also passed round copies of the American photo- 
graph taken at Jerez in Spain, of Mr Brothers’ photograph, also 
an enlarged copy of the latter and a reduced copy of the former, 
so as to bring them to the same scale, mounted so as to shew 
the resemblance between the two photographs taken at a dis- 
tance of 1200 miles apart. 
There were exhibited on the screen some maps to shew the 
geographical position of the observing stations, and, side by 
side, drawings made by Mr Hudson and by Mr Browne, 
of Wadham College, Oxford, from their sketches of the 
corona. 
Mr CuirrorD, who was with the Sicilian Expedition, de- 
scribed its comparative failure, but said that some observations 
made when the disc of the moon was comparatively free from 
clouds confirmed Mr Hudson’s to a great extent. 
Mr Moutton, who was stationed at San Lucar, was of opi- 
nion that the polarization seen was attributable to defective 
instruments. Experiments had proved that polarization was 
not observed when the polarizer was placed, not at the eye-end, 
but at the other end of the instrument. The instrument had 
been thus used by the American observers, and they had never 
been able to detect radial polarization, His own experience, 
however, would not throw much light on the subject, owing to 
the tantalization of the clouds at the time of his observations, 
and when the eclipse was approaching totality. He could
