witli gravel or small stones between tbe parallels of 56° 55' and 

 57° 30' at a distance of 25 to 65 miles from the shore; while 

 around this area, except close to the coast, the bottom consists 

 for the most part of a fine sand, approximating in some cases to 

 hard mud. 



The temperature at the bottom showed a slight decrease as 

 the distance from the shore increased (irrespective of depth), as 

 within twenty miles from the shore it varied from 48° to 53° in 

 depths of from 28 to 55 fathoms, while at 100 miles from shore the 

 range was from 46° 5' to 50"^ in depths of from 46 to 56 fathoms. 



In the observations taken on board the ' Triton,' and kindly- 

 furnished by Captain Tizard, the following results were observed
