In the preceding tables the abbreviations for the bottom are from the 

 followinc- code : 



In the mouth of February the ship was swung- in the Gulf of Paria, 

 latitude 10^ 30' i^^., longitude 61^ 35' W. The azimuth of the sun was 

 observed on every alternate point on even beam, swinging first with 

 starboard and afterwards with port helm ; and on every fourth point, 

 while listed about 5° to port and 5^° to C^Q to starboaxd, swinging both 

 times with starboard helm. From the mean deviation table, derived 

 from the two swingings on even beam, a steering-card was constructed 

 (see Plate I). In it the inner graduated circle shows the magnetic 

 courses to be made; the lines radiating from it to the outer circle indi- 

 cate on the latter the corresponding courses to be steered by the stand- 

 ard compass. 



The effect on the deviation of listing to either side was similar to that
