This table does not take into account the greater evaporation of the summer than 

 the winter months. If this could be applied as a correction, it would notably reduce 

 the amount of rainfall received between March and September, and increase that 

 between September and March. 



Temperature of the Air. 



In order to complete the summary of meteorological conditions, Tables X., XL, 

 XII. , XIII. are given. The)?- have been compiled for me from the records of the 

 Scottish Meteorological Society, by Mr R. C. Mossman. The discussion of these 

 conditions will be undertaken in Part III., which will deal with the general thermal 

 conditions of air and water in the region under investigation.
