296 FURTHER OBSERVATIONS ON THE 



It appears that the commencement has been anticipated 6" 

 or 7" by some error, let us see whether this doubt can be 

 cleared up. 



The solar eclipse of the 26th of June 1805 was observed by 

 Mr. Ellicott in Lancaster.

 By this comparison it appears that the error is in the commencement at 



Lancaster, and that the difference of the meridians of the two places is = 10 08 6

These results confirm the allowance of the irradiations of 

 the semidiameters which I have adopted, it being very proba- 

 ble that the beginning was delayed 2". 



M. De Lalande, member of the Board of longitude, has favor- 

 ed me with an answer to the observations I communicated to 

 him, it is dated Paris, 27th September, 1806, and states that he 

 had calculated my observations at Kinderhook, and that he found
