new style, l682, and that I duly observed it from that time till Sept. 7. As to 

 the path of this comet, with its velocity, and the angle of its orbit made with 

 the ecliptic, these may be gathered from the following table : which, however, 

 it may be observed is not composed from any accurate calculation, but is de- 

 duced by a looser way of reasoning, from a consideration of the globe. 



So that, by its proper motion in its orbit, from Aug. 26 to Sept. 1 3, it has 

 moved over 83° 27', and in the ecliptic 9 1*' 30'; also its latitude first increased 

 to 26° north, and then decreased to 12° 30'. — It may be remarked, that its 

 northern node is in 24° of y , and its southern node in 24*^ of tT)^ ; but its limits 

 were in 24° SI ^"^ ^'' The angle of the orbit with the ecliptic was nearly 26°. 

 But whether for its whole duration it was entirely consistent with its nodes, or 

 whether it varied, and how much, will appear from the calculation. — As to its 

 appearance, the head was rather brighter and larger than that of the year ] 68 1 

 but, on the other hand, it had a much shorter tail. With a long telescope we 

 could observe in the head only one nucleus, and that always of an oval and
