The declination of the fun added to this, amounts 
to 46° 30' 31", the true latitude, as diredly com- 
puted, being 46° 30' 19". 
However, it muft not be expected, that this me- 
thod of computation will always converge thus expe- 
ditioufly to the true latitude. Had thefe obfervations 
been made about 3 hours fooner in the day, and 
with the fame interval between them, if the firft al- 
titude of the fun had been found 18 0 55, and the 
fecond 33 0 11', the latitude computed would come 
out wider from the truth, than that aflumed, one 
exceeding, and the other falling fhort of the true la- 
titude, which will lie between them, and is nearly 
the fame, as above. But if the left'er altitude had
