VmU WEST COAST OF SCOTLAND AND THE IRISH SEA. 



25 



13-1° C. on July 19th, ofF the N. point of Eigg. Durmg the same period 

 the surface temperature off Port Erin in the Irish Sea ranged from 11-6° C. 

 to 13-8° C. 



As my main object was to obtain samples of vertical hauls from the deeper 

 parts of the British seas, 1 selected localities off the West Coast of Scotland 

 where the charts showed depths of over 50 fathoms, and where possible of 

 over 100 fathoms. In addition to surface gatherings and the Irish Sea 

 series, I have now 33 successful vertical hauls in Scottish waters from 

 depths of over 50 fathoms and 18 from over 100 fathoms (see fig. 8, p. 38) 

 The deepest are :— 133 fathoms, between Croulin and Longa Islands in the 

 Sound of Raasay, and 130 fathoms between Canna and Rum, south of Skye. 



The localities may conveniently be grouped in three series : (1) those north 

 of Oban, (2) those further south in the Clyde sea-area, and (3) those in the 

 Irish Sea. The northern Scottish series number 41, the southern series 26, 

 and those from the Irish Sea, from depths over 50 fathoms, are 6G *. The 

 list of localities is as follows, arranged according to the day of the month 

 irrespective of years : —
