cane,—as the cireles of its gyrations open and extenes the storm 
is progressing towards spending its fury, and disappearing. Al- 
though it did not bear directly on the question now under discus- 
_ sion, yet he could not help saying, that there are circumstances 
connected with the spots on the sun, which forcibly impressed 
his mind with the idea of tornadoes in the solar atmosphere, 
which, by scattering and opening out the luminous superficial 
matters, laid bare the opake and dark mass beneath. It had at 
all times been a question. with astronomers, how the spots were 
formed, supposing the luminous matter of the sun to be a merely 
superficial and uniformly spread stratum ; but something like vio- 
lent hurricanes being supposed to take plana in the solar atmos- 
phere, the difficulty is much diminished, if it did not entirely 
disappear ; and in truth the appearance of the spots within the 
last year or two, was such as farther to induce the supposition of 
something in the solar atmosphere very like our trade-winds, for 
whereas, most usually, the spots have been scattered not very 
regularly over each hemisphere, they have latterly’ appeared 
more in lines following each other in succession, and having ap- 
parently an inclination towards the sun’s equator on each side. 
If decided indications of any thing like trade-winds should, by 
this or other circumstances connected with the spots, be detected, 
the other conclusions. would be much strengthened. 
_ Herschel’s Astronomical Observations at the Cape of Good 
Hope. These were reported under the following heads. 1. Re- 
duced Observations of 1232 Nebule and clusters of Stars, made 
in the years 1834, 5, 6, 7,8, at the Cape of Good Hope with the 
20-feet Reflector. 2.. Fadticed Observations of 1192 Double Stars 
of the Southern Hemisphere, made.as above. 'The observations 
in these two papers form parts of two catalogues of southern neb- 
ule and double stars respectively, which comprise the chief re- 
sults of his astronomical observations at the Cape. They are 
complete only as far as the first nine hours of R: A. In the other 
hours, only a few of the objects which occur are added, being 
the results of a partial and very incomplete reduction of the ob- 
servations in those hours. Sir. J. thought that when all the ob- 
servations are reduced for the catalogues, the number of objects 
contained in them will be nearly doubled. The first catalogue 
contains all the numerous nebule and clusters comprised in the 
two Magellanic clouds. Each reduced observation expresses the
