Dr. Herschei/s Observations on the 
2 h 35 f . The quintuple belt is still faint. The southmost belt 
much fainter than the northmost ; the latter is not only 
stronger, but also broader than the former. ( q ) 
Jan. 7. i b 4'. (Cor. — 8' 25", o by a transit.) The three 
dark belts of the quintuple belt, seem not to differ much in 
colour and breadth, but the evening is very indifferent, (r) 
i h 53'. The air is a little clearer. The southmost is very 
little (if at all) less dark than the northmost ; they are all 
very faint. ( s ) 
3 h 18'. As well as the night will permit to see, I judge the dark 
belts to be pretty equal in colour and size, the northmost, how- 
ever, is still a little darker, and broader than the other two. ( t ) 
3 h 44'. The dark belts seem to be as equal as I have seen 
them at any time. I see them very well. («) 
Trial of Concave Eye Glasses. 
I tried five new concave eye glasses, but they all proved defec- 
tive in figure ; with one of them, power 360, I saw the quintuple 
belt pretty well. With regard to the field of view they are full as 
convenient as convex glasses, (v) 
5 h 50'. The three dark belts are still nearly alike, and uni- 
formly divided by the bright ones, (w) 
Jan. 16. 2 h 32'. (Cor. — 8' 28 ",6.) I suppose this to be the 
part of the quintuple belt, which is nearly uniform ; the south- 
most one however is not quite so dark as the northmost. (x) 
4 h 20'. The belts seem to be equal and uniform through- 
out. (y) 
5 h 5'. The belts Seem to be uniform ; the southmost how- 
ever is the faintest, (z)
