limb. Dec. 23 it was streaky, and there appeared to be a thin 
bright zone in its centre : this was again suspected Jan. 20, 
when a minute luminous stripe seemed to divide it into two 
very unequal portions, the narrower North ; but it was a very 
difficult observation : this occurred during one of its browner 
aspects. Insulated portions of such, a zone, and dark spots, 
were at other times more readily perceived. Dec. 21,1 thought 
there was a lighter included portion for about one-fourth of its 
length in the centre of the disc. Jan. 9, a similar break inter- 
vened between two dusky, probably roundish spots, about one- 
sixth of length apart. Jan. 25 and 26, there were two such 
spots, without any perceptible stripe between them ; the time 
of rotation shows that these must have been different, and there 
were probably many. Feb. 7, I suspected that there were two 
smaller spots, connected by a lighter space, and a larger one 
further advanced across the disc. March 22, there was a dark 
knot on the belt somewhat beyond the centre, from which a 
ragged projection slanted a little way North-East into the 
brighter adjacent space : for about one-fourth of its length 
from that knot the great belt seemed paler ; but I could not 
make out with certainty whether there was a second spot where 
it recovered its usual tone. 
The North Temperate Zone was still noticed from time to 
time to be the most luminous part of the globe, but only slightly, 
and not, as formerly, conspicuously so. It was also not quite 
so free from disturbance. Jan. 25, when there were two dark 
spots in the adjacent North temperate belt, I had at best 
moments a difficult glimpse of something like a very thin 
dusky loop, or inverted festoon, connecting them, and project- 
ing across one-third of the breadth of this zone. On the follow- 
ing night I fancied a very narrow dark stripe across the disc 
close to the edge of the North temperate belt, not verified, 
however, some hours later. March 22, when there was, as just 
described, a ragged projection from this great belt to the North, 
I had a doubtful suspicion that the central part of the belt was 
attended by some very slight wispiness, or thin loops, intruding 
into this zone. 
We now reach the Equatorial Region , which seemed un- 
altered in its proportions, and on Nov. 18 was observed to lie 
obviously South of the centre of the disc. Its colour, un- 
changed, though probably diluted, has been already adverted to. 
The two Torrid Zones were often noted as narrow, and often as 
equal ; but the South was sometimes considerably broader and 
darker than the North, which, on Jan. 26, was barely visible. 
The markings in the included space, though seldom so clearly 
made out as formerly, had exactly the same form, and the 
6 bead-and-hollow ’ character was always apparent, whenever the
