328 'Sir -W illiam Herschel's observations and experiments 
maps is assigned to it. In this situation it began to appear 
at 6 or 7 degrees from where it might have been expected 
to enter the telescope. 
Aug. si, 1791. Right ascension i8 h 59'. Polar distance 
from 84° 15' to 86° 17'. The milky way comes on very 
suddenly, and is amazingly crowded with very small stars in- 
termixed with many of several sizes. 
By our maps this place is already within the limits of the 
milky way. 
Jan. 1, 178b. Right ascension 5 h 17'. Polar distance from 
89° 28' to 91 0 47'. Most of the stars are larger than usual, 
but the whole breadth of the sweep contains a great mixture 
of all sizes. 
From the brightness of the stars we may conclude that 
the constellation of Orion to which the observation belongs, 
is one of those that are nearest to our own situation. 
Dec. 27, 1786. Right ascension 6 h 49'. Polar distance from 
87 0 37' to 8 9 0 55'. From the appearance of the heavens in 
this neighbourhood, there is reason to suppose that there is a 
break or vacancy among the stars between our situation and 
the more remote parts of the milky way. 
The place to which this observation refers is in the breast 
of Monoceros. 
Oct. 14. 1787. Right ascension 22 h 14'. Polar distance 
from 35 0 1 8' to 38° 50'. It is very evident that in this part 
of the heavens there is some distance between us and the 
milky way, which is not equally scattered over with stars. 
The situation of the place pointed out by the observation is 
near the crown of Cepheus. 
Sept. 15, 1792. Right ascension 19** 46'. Polar distance
