RULES FOR FINDING T^ LATITUDE. 367 



2. If the sun has south declination, and is southward LECT 

 of your place at noon, add the declination to the meri- ,^-y-x 

 dian altitude ; the sum, if less than 90 degrees, is the 

 complement of the latitude north : but if the sum exceeds 

 90 degrees, the latilude is south; and if 90 be taken 

 from that sum, the remainder will be the latitude. 



EXAMPLES. 



The sun's meridian altitude .... 65 10* South 

 The sun's declination, add . . . . 15 30 South 



Complement of the latitude. ... SO 40 

 Subtract from 90 



Remains the latitude 9 20 North. 



The sun's meridian altitude . . . 80 40' South 

 The sun's declination, add .... 20 10 South 



The sum is 100 50 



From which subtract . 90 



Remains the latitude 10 50 South. 



3. If the sun has north declination, and is on the 

 meridian north of your place, add the declination to the 

 north meridian altitude ; the sum if less than 90 degrees, 

 is the complement of the latitude south : but if the sum 

 is more than 90 degrees, subtract 90 from it, and the re- 

 mainder is the latitude north. 



EXAMPLES. 



Sun's meridian altitude GO 30' North 



Sun's declination, add 20 10 North 



Complement of the latitude .... 80 40 

 Subtract from . . . . 90 



Remains the latitude 9 20 South
