Where the difference is prefixed by the negative sign — it shows that 

 the temperature of the water was superior to that of the air ; when there 

 is no sign prefixed, or where it is positive, -J- it shows that the air was 

 higher in temperature than the water.

On looking over these differences, and also the mean results for each 

 geographical group of stations, it manifestly appears that the air and 

 water temperatures differ least on the coasts of Ireland, and especially 

 on its south and west coasts ; and we may conclude, therefore, that on 

 these coasts the ratio of the warming influence of thermal currents com- 

 pared to that of direct sunshine is at its maximum. On the contrary, 

 the comparative influence of sunshine seems to be greatest for the group 

 of stations on the west coast of France. 



The general conclusions Avhich may be drawn from the observations 

 under discussion are in harmony with the results previously obtained. 

 Thus, in 1851 observations on sea temperature on the coast of Ireland, 

 in connexion with a series of tidal and meteorological observations, were 

 made under the superintendence of the Council of the "Royal Irish
