OBSERVATIONS 



* If this obfervation, which appears to have been inaccurate, be ftricken 

 ©ut, the mean of the remaining ten will agree with the mean of a like num- 

 ber of obfervatioTis made on die eclipfes of Jupiter's fatellites, within 2^fingle 

 Jecorid. This faft is a ftrong proof in favour of the accuracy of this method 

 of determining the longitude of places.
