of the Pleiades ; its northern boundary passed over the star y Pe- 
gasi, and its southern five degrees south of Venus. February 
13, at T'- 20“, the light could be traced to a point about three 
degrees east, and half a degree north, of the Pleiades ; and 
the intensity of the brightest part was nearly equal to that 
of the Milky Way in Cepheus. When compared with the 
white light of the Milky Way, the Zodiacal Light had a soft 
ruddy tinge. The breadth of the cone at about 54° from the 
apex, was estimated to be 18° or 19°. The axis passed over 
f Arietis. February 14, at 7^ 50“, the Zodiacal Light was 
broader and brighter than on the previous evening. The 
brightest portion was about the star e Piscium, and it was 
certainly brighter than the Milky Way in Lacerta and 
Cepheus, but not so white. The lower part of the northern 
side was more extended than had been observed on previous 
evenings, but this was probably owing to the presence of 
faint Aurora near the horizon in the north-west. February 16, 
at 7^ 20“, the axis of the Zodiacal Light passed midway 
between (3 Arietis and Ceti, and about half a degree north 
of the Pleiades. The brightness of the light near e Piscium 
was estimated to be one-third greater than that of the Milky 
Way in Cepheus or in Orion and Monoceros. The northern 
boundary appeared to extend outwards as it approached the 
horizon, or to have a concave form. The bright light of Venus 
did not affect the Zodiacal Light beyond a distance of 5° or 6°. 
February 19, at 7*' 30“, the Zodiacal Light extended to (p 
Tauri. The brightest part was in the triangle formed by 
the stars e, rj, and o Piscium, and was nearly, if not quite, 
twice as bright as the Milky Way in Monoceros and Cepheus. 
At the breadth of the cone at 42° from the apex was 
estimated to be about 13°. Cloudy weather and moonlight 
have since prevented further observation. 
The position of the apex of the cone of light and its 
angular distance from the Sun on the evenings of observation, 
were as follows : —
