down, after tracing the apparent course on the Planisphere, by 
means of a soft Pencil. ‘ 
The Observer should then dictate, for the Assistant to write 
down, the rough apparent direction, as for instance, “ from left 
to right, level,”’.“ from right to left, inclining a little upwards,” 
* from above downwards, direct,’’ ‘* from below upwards, inclin- 
ing much to the right,” &c.: next he should mention, whether 
the apparent course was straight or otherwise, whether long or 
short; whether the object was minute, small or comparatively 
large ; whether faint, bright or brilliant ; all which, and any other 
observable circumstances, being noted down, this observation may 
be considered as finished. 
It will be desirable, that the Observer while dictating these 
circumstances to the writing Assistant, should again have his Eye 
fixed on the central Star, in readiness to notice, the ¢ime and 
rough direction, at the least, of any other moving Body, which 
he may not be able to notice further, without endangering con- 
fusion, or the loss of observations already made, but not re- 
corded. 
A third Assistant at hand, will be very useful, to relieve instantly 
the Observer, when tired, or having occasion to consult the Plani- 
sphere, or revise the observations already written down, &c.; or 
in case of two Assistants only being present, it may be necessary 
that one of them should occasionally relieve the Observer. 
When the one, two or three Hours allotted to these observa- 
tions, shall have concluded, or the coming on of Clouds may sooner 
terminate the Evening’s observations, the hour and minute of such 
termination should be noted down: and after the pencillings on 
the Planisphere shall have been compared, with the written de- 
seriptions of the apparent courses, the same may be rubbed out, 
ready for the next night’s operations. . 
I shall not at this time trespass further on your pages, by men- 
tioning such preliminary a’ rangements and precautions as will be 
necessary, when simultaneous observations are intended, by two 
Observers, situate at several Miles distance from each other, be- 
cause most of these are sufficiently alluded to already, in my 
Queries referred to. 
I am, sir, 
Your obedient servant,
