Fisher Ort the Variation of the Compass. 85 



REMARKS. 



By Walker's Compass. 



By Walker's Compass. Ship perfectly steady, taken a stand 

 placed on the companion between the binnacles. 



By Kater's Compass. Taken in the starboard-quarter boat. 

 Ship tolerably steady. Card traversed considerably. 



Amplitude O by Walker's Compass. Ship very steady. Taken 

 in the starboard-quarter bout. 



By Walker's Compass on the starboard gangway. Observed to 

 differ 8° from both the binnacle compasses being too much 

 easterly, making the variation by them 25°.52 W. By 

 bringing the compass nearer to the binnacle the difference 

 decreased, and upon placing it on the companion between 

 binnacle compasses, it exactly agreed with them ; indicating 

 some powerful attraction near to where the observations 

 were made, arising, most probably, from the quantity of iron 

 stowed round the main-mast, consisting of shot, chain-cable, 

 spare rudder with an iron bolt, and the iron fenders. On 

 the forecastle, and just abaft of it, are the spare anchors. 



By Walker's Compass on the starboard gangway differed 8° 

 from binnacle compasses, variation by them 27°.2r W.
