tlCCOHM't OF TflE METKOR SEEN IN CONNECTICUT* g J l 



c^fve(5, tha! Tiis recollection of the meteor was pretty dis- 

 tmct, and that he was enabled to determine its situation by 

 the position of certain known objects. 



Deductions from the precedinff observations. 

 , The observations made at Wenham, combined ipi various Calculation* 

 ways with those at Rutland and Weston, by the methods ^Xg^obJerr- 

 given in the preceding problems, furnish the results con- ations. 

 tained in Table 1, in which the j^iven quantities are marked 

 with an asterisk. These quantities are varied a few de- 

 grees in the different examples, for the purpose of forming 

 an estimate of the change in the calculated place of the 

 meteor, from any supposed errour in the observations. In 

 the two first examples are combined (by Problem 2) thfe 

 azimuth and altitude observed at the first appearance of 

 the meteor at Rutland, with various supposed altitudes at 

 Wenham. The 3d and 4th examples are like the first and 

 second, except in a small change in the altitude and azi- 

 muth at Rutland. In the fifth and sixth examples, the 

 first azimuth and altitude observed at Wenham are com- 

 bined (by Problem 1) with the azimuth at Weston, sup- 

 posing it in the 5th example to be north ; and in the 6th 

 IN 3** W. The 7th and 8th examples contain the results 

 from combining the same Wenham observation with the 

 azimuth at Ttutland, supposing it in the 7th example to be 

 N 170" 30' W, and in the 8th N 173' W. From the 9th 

 to the 1 2th examples, the same calculations are repeated 

 with the second Wenham azimuth and altitude. In the 

 13th example, the azimuth and altitude at Weston, at the 

 time of the disappearance of the meteor, are combined with 

 the altitude at Wenham, supposing it 5°: in the three fol- 

 lowing examples the calculation is repeated with small va- 

 riations in the values of the given quantities. The azimuths 

 at Wenham, calculated in the 13th and 14th examples, are 

 made use of in the 17th, 18th, and 19th, with the corre- 

 sponding assumed altitudes at Wenham, and the azimuth 

 at Rutland at the time of the disappearance of the meteor, 

 supposing it to be N 172** W in the 17th and 18th examples, 

 and N 170° 30' W in the igth. 



It appears by this table, that in the 5th and Gtli examples
