We have here for Scarborough a hiberno-^estival difference 

 of only 17^ degrees, the reduction, as compared with York, 

 being effected by the lowering of the maritime temperature in 

 Spring and Summer, whilst it is kept higher than at the inland 

 station in Autumn and Winter. As compared with what it is 

 at an inland station the warm weather is in fact postponed at 

 the sea-side. The winter temperature is warmer at the sea- 

 side than at an inland locality because the sea cuts off the 

 excessive cold. The spring temperature is warmer at the inland 

 station than at the sea-side, because tlie sea absorbs heat from 

 the air to make up for what it has given out in winter. The 

 summer temperature is warmer at the inland station than at the 

 sea-side because the sea cuts off the excessive heat. The 

 autumn temperature is warmer at the sea-side than inland 

 through the sea then giving out the heat it has absorbed in 

 summer. This variation and the cutting off of the daily means 

 are the change as regards temperature which is brought about 

 by a maritime situation. 



For a difference in level of fully 400 yards between York and 

 Allenheads a reduction of 3 degrees of mean annual tempera- 

 ture is under the average mark. The balloon experiments 

 made under the ausi)ices of the British Association for the 

 Advancement of Science give a diminution of one degree of 

 Fahrenheit's scale for 276 feet. For Central Europe Humboldt 

 gives the diminution at one degree for 267 feet. The registers
