possible in any other compass, and the card, if disturbed, returns to rest in much 

 less time. The card is usually made with a curved ring bearing the divisions, 

 which is preferable, except when it is desired to be graduated to degrees. The 

 card with degrees is engraved upon a plane annular ring ; for use when the courses 

 are desired to be given in degrees rather than by points, and which is necessary 

 for azimuth observations. It has EKECT figures, which are very legible.
