CLYDE SEA AREA. 



51 



The rate of gain and loss of heat by the mass of water as a whole, and by the upper 

 and lower layers, is given in Table XV., which shows the best results that our work on 

 the Clyde Sea Area produced regarding temperature changes in comparatively short 

 intervals of time. Sounding No. 25 is omitted from consideration, because it was made 

 under different conditions, and possibly not quite in the same place as soundings 24 and 

 26. The effect of the different behaviour of heated and chilled surface water is brought 

 out by the much greater average rate of cooling than of heating.
