The distance observed April 1 2, 1 824, does not well accord with cither of the sets ; 

 at the same time nothing appears in the rough journal to invalidate the accuracy of 

 the former ; on the contrary, it would seem that the stars were brighter on that 

 night, than on either of the other nights of observation : the discordant series 

 therefore cannot be rejected with propriety.
