VI. Account of some Particulars observed during the late Eclipse 
of the Sun. By William Herschel, LL.D. F . R. S. 
Read January g, 1 794. 
It will be proper to remark that my attention, in observing 
this eclipse, was not directed to the time of the several parti- 
culars which are usually noticed in phaenomena of this kind ; 
such as the beginning, the end, and the digits eclipsed. I was 
very well assured that the care of other astronomers would 
render my endeavours, in that respect, perfectly unnecessary. 
The only view I had was, to avail myself of the power and 
distinctness of my telescopes, in order to see whether any ap- 
pearances would arise that might deserve to be recorded ; and 
the following particulars will, at least, serve to point out the 
way for similar observations to be made in other eclipses, 
where different circumstances may chance to afford an oppor- 
tunity for gathering some addition to our knowledge, with re- 
gard to the nature and condition of the moon, or of the sun, 
and perhaps of both these heavenly bodies. 
Sept. 5, 1793. 8 h 40' 3" by the clock.* My attention being 
directed to the place where I supposed the first impression 
would be made, I perceived two mountains of the moon enter 
the disk of the sun, as delineated at a, b, fig. 1, Tab. VII. The 
* By account, my sidereal time-piece was about 5' i u ,y too forward ; but, as no 
transits had been lately taken, there may be an error of some seconds.
