the continental coast and find evidence, in the sharp southward 

 bending of our isotherms, of the low winter temperatures which 

 characterise the coastal waters. 



Both of these latter charts, of mean maximal and mean minimal 

 temperature, become considerably simplified when we translate them 

 into charts of maximal and minimal anomaly. 



In Fig. 10 we see the anomalies, as compared with 15° W,, in

respect of mean Maximal Temperature, and these isanomalies, as 

 will be at once seen, are of a simple and regular kind. Everywhere 

 as we approach land, the maximal summer temperature (as calculated 

 from the fundamental sine-curve) is higher than in the open ocean at 

 corresponding latitudes, and everywhere the ditf'erence gets greater 

 as we pass farther and farther into the narrow seas. In the English 

 Channel and the southern portion of the Irish Sea, the mean
