EXAMPLE II. 
Let the real latitude be io° o' o", and the two observations 
be made on different sides of noon ; one when the sun’s dis- 
tance from the meridian is 5 0 o' o", and the other when his 
distance is io° o' o" ; the declin. in the former case being 
7 0 40' 40", and in the latter 7 0 39' 43", of the same kind as the
