dire&ion, till coming over Fort William, in the {hire 
of Invernefs, after a courfe of about 400 miles, it 
there fuddenly difappeared. 
But, notwithftanding the extinction of the meteor 
at this place, it feems {till to have proceeded north- 
wards ; lince it was feen again, in a luminous {late, 
in a globular form, but without a tail, about the yS° 
of latitude, on the weftern coaft of the {hire of Rofs, 
almoft vertical to the obferver ; moving then to the 
fouthward of the eaft ; that is, in a direction almoft: 
contrary to the fir ft : and in this laft courfe, of which 
we know not the end, it poffibly might have gone 
a great way to the eaft ward. 
During the fir ft part of its progrefs, viz. from 
Cambridge to Fort William, it went obliquely down- 
wards, in fuch a manner, that, by computation, it 
muft have been from about 90 to 100 miles high at 
the firfit of thefe places, and between 26 and 32 miles 
at the laft. But at what height it was afterwards feen 
in the fhire of Rofs, is not to be determined, fince 
one obfervation only was tranfmitted to me from that 
country. As Dr. Mackenzie obferved it nearly over his 
head, and yet of a fmaller fize than the full moon 
when fome hours above the horizon, I fhould fufpeCt, 
that, after its defcent to Fort William, it had re- 
afcended at the time he faw it ; becaufe he probably 
would have defcribed it as a larger body, if then not 
higher than when it firft difappeared. 
This dipping and riling, in the courfe of a meteor, 
is not more extraordinary than its lateral deviation 
from a {freight line, as I have elfewhere {hewn*. Such
