the two Shoulders of Orioff, The Latitude of the 
place being nearly %o', and Longitude fTr/? from 
London o°. 45'. Let them try how they can account 
for its being (een five Degrees high at Aberdeen in Scot- 
land, and near as much at Peterhead half a Degree more 
Northerly : and then they will be better able to judge 
whether it did not exceed the reputed Limits of our 
Atmofphere. Laflly, if the apparent Altitude of the 
Meteor at Parts was not 5r but ii gr, on the If' 
Point, when it muft have been in its greatefl: Luftre, 
there will be no pretence to bring it lower than 1 have 
made it, efpecially if it be allowed to have follow’d 
the Track I have allign’d it, over Prejlaln, Cardijf, 
Minhead, Tiverton, and Breji in Bretan'j. 
Allowing this to have been the Path it mov’d in, it 
would be eafy to aflign the real Magnitude and Velo- 
city of this Meteor, if the feveral Accounts of its ap- 
parent Diameter, and of the Time of its Paflage from 
one of its Explofions to the other, were confident with 
themfelves. But fome of them making its vifible Ap- 
pearance nearly equal to the Sun’s, w'hich in the Opi- 
nion of many it far exceeded, we may fuppofe with 
the lead that, at the time when it fird broke out o- 
^*er Tiverton, its Diameter was half a Degree, And its 
Horizontal Didance being * yo Geogr. Miles from Lon- 
con, and its Altitude 60, the Hypothenufal or real Di- 
dance from the Eye will be more than 160 fuch Miles; 
to which Radius the Subtenfe of half a Degree will 
be above an Englilh Mile and half, being about 2800 
Yards quamproxime: After the fame manner it is dif- 
ficult to aflign its due. Velocity, whild forae make tc 
half, others lefs than a quarter, of a Minute, in paf^ 
dng from its fird Explofion to its lad Extindion: 
But the Didance it moved in that time being about 
3 gt, or 1 80 Geogr. Miles, we may modedly compute 
.7 N it
