with one another will gain them a degree of credit, to which,

a, In a letter, from Perth in Scotland it is Gide Rea “ a 
€* sentleman, who has avery g good eye, obferved the meteor 
«* pafs about 6° to the weftw oe of the zenith ;” and a Pro- 
feflor in one of the Uni verfities, being at Ardoch on the banks 
of the Tweed, about two miles below Dunbarton, judged it to 
have ‘‘ at leaft 45° of elevation above the horizon.” Thefe 
ees would make its real height 57 ftatute miles, 
. At St. Andrew’s in Scotland, ‘‘ it was not quite vertical, 
“a he according to fome was 20° or 2 5° from the zenith, ac- 
“cording to others not fo much.” Taking the greateft of 
thefe diftances as neareft the truth, fince we are ufually led to 
eftimate altitudes greater than they really are, this obfervation, 
calculated with that of Ardoch, gives 60 miles for the height. 
_ For the communication of thefe obfervations, collected by 
his friends, I am indebted to General MELVILL FR, o> 
At Edinburgh the meteor pafled very near the zenith, in 
which cafe a deviation of a few degrees is rw pereetol 
to a common eye. 
The rev. Mr. Watson of Whitby, in a letter to hand 
Muicrave V.P.R.S. is very confident, that the greateft 
altitude of the ce which pafied to the weftward of his 
zenith, was 60°. Mr. Epceworrtu F.R.S. in his letter to. you, 
Sir, ftates its elevation at Edgeworth’s- -Town near Mullingar, i in 
Treland, as ro° or 12° above the eaftern horizon. Thefe obferva- 
tions, calculated ftri€tly from the latitudes and longitudes with 
the allowance for the curvature of the earth, as indeed, were 
all the reft where the difference would be fenfible, give 57 
miles for the height of the meteor.
