It moved ic-a' direction nearly parallel to the horizon, and 



disappL'jired behind a cloud to the northward of tlie house 



of Samuel Biaiichard, Esq. The true azimuth of the Azimuth-^ of 



fiouth part of the burn from the place of observation is ^.Q^^^figQ,!^ 



N. 107" 59' W. its altitude 3^* 25'. The top part of the 



buildintj^ is horizontal. The azimuth of Mr. Blanchard'a 



house is N. 148° 22' W. These buildings were useful in 



determining nearly the limits of the azimuths of the meteor. 



The azimuths were obtained by observing with an excel- Method of oil* 



lent theodolite the difference of the asiimuths of the gun ^^^"^"fi.*^'®"'* 



and object, and finding the sun's azimuth by his ©bserved 



altitude. The same method was made use of in obtaining 



the azimuths of the meteor. The angular elevation of the Elevation and 



meteor above the horizon appeared always greater than that azimuths of

 the altitude of the top of this tree was 7* 10'. These fixed 

 objects served to determine the altitude of the nieteofj 

 which is the most important element in the calculation, to 

 a considerable degree of accuracy. After the theodolite 

 was carefully adjusted, Mrs. Gai*dner directed the telescope 

 attached to the instrument towards that part of the heavens 

 where she first saw the meteor; the true azimuth wa§

 Altitude as before. The azimuth of a third place was 

 N 132'* 15' 54" W. Altitude 5° 29' 40". The azimuth of 

 the place of disappearance was N 144° 33' 54 " VV, Alti- 

 tude 4° l' 40"*. All these azimuths fall within the litnits 

 mentioned above, but the two last are undoubtedly too 

 great. For a great circle passing through Wenham and 

 Weston is inclined fo the meridian of Wenham by aft 

 angle equal to 125° 18' 38 ", and as the two last azimuths 

 exceed that quantity, they fall to the southward of Westoh, 

 which cannot be correct, because the meteor disappeared 

 before it arrived at the zenith of Weston, as was observed 

 by Judge Wheeler. It happens fortunately in the present
