tremely simple diagram, which may be sufficiently described by 

 saying that the curves of equal amplitude tend on the whole to run 

 parallel with the Continental coast, from the Norwegian coast south- 

 wards, and that all but the innermost (and highest) of them have 

 been, as it were, thrust outwards towards the ocean where the British 

 Islands jut out from the Continental land-mass.

In Fig. 8 we represent the mean maximal temperature of the year, 

 as determined from the first sine-curve ; that is to say, the values 

 represented are those of the mean temperature plus the half ampli- 

 tude. The chart is a simple and regular one, and its chief features 

 have already been referred to in connection with the corresponding 

 chart of the North Atlantic. The contour-lines of equal maximal 

 temperature, which run approximately east and west in the ocean, 

 are bent strongly northward, firstly, along the west coasts of Great 

 Britain and Ireland, and again still more markedly towards the Nor-
