in temperature, the greatest diversity occurring at or before the maximum. Thus 

 in July and August 1886 the Gareloch was 5° "6 and 5° "9 warmer than Loch Goil, and in 

 September the Channel was 6° "2 warmer than Loch Goil. In July and August 1887 the 

 Gareloch was 6° "8 and 7° "6 warmer than Loch Fyne, and about 6° warmer than the 

 Arran Basin, the influence of depth and isolation showing itself to the full.

In Table LXV. the annual periods of temperature change are compared for the various 

 divisions, the data being in each case taken from the curves and detailed tables which 

 have already been fully discussed. The mean annual range, Nos. 5 and 10, is the 

 difference between the monthly temperature for the coldest and warmest month of the year, 

 as detailed in Tables LXIII. and LXIV. The values relating to surface conditions, and 

 to those connecting surface and air, are averaged in the last column, as the air and surface 

 layer of water being each continuous over all the divisions, may be looked on as parts of
