mainly corroborate Mr Hudson; the observation of the V gap, 
however, was wanting. 
He then read a very interesting communication from Father 
PERRY, summing up the results of the spectroscope observations 
at the various stations. 
Starting outwards from the photosphere, Prof. Young and 
Mr Pye had proved the existence of a thin absorption band 
covering the photosphere, and ordinarily giving rise to the dark 
lines: this, as soon as the photosphere was eclipsed, burst forth 
as an innumerable mass of bright lines, to last only for a second 
or two, and then itself to be eclipsed: passing through the chro- 
mosphere, we come to an outer layer of cooler hydrogen, whose 
tale has been told by the spectroscope of Mr Abbay, and then 
at last to a hollow shell of green vapour, lighter than hydrogen, 
whose spectrum is the bright green line 1474, extending into 
space far beyond any measurable limits, and which will probably 
enter largely into all future theories of the ether of space. 
Mr CLIFFORD added a few words, maintaining that the dis- 
turbing causes did not apply to the instruments which he was 
using.
