after the maximum of the air-temperature was 49 days in 1886, and 36 in 1887 ; while 

 for the bottom layer of ten fathoms it was 70 in 1886, and 80 days in 1887 ; an average 

 of 42 for surface and 75 for bottom retardation. The retardation for the deep water was 

 less than half as great as for the same depth in Loch Goil, 60 per cent, shorter than for

Loch Fyne, and 40 per cent, shorter than for Loch Strivan ; the obvious explanation 

 being the much greater freedom of circulation in the Dunoon Basin than in the enclosed 

 lochs. In other words, change of temperature throughout the mass is carried on more by 

 mixture than by conduction.
