but was nevertheless calculated to give an approximate result when great 

 accuracy was not important. It had been found that the evaporation 

 from the evapometer exceeded that from the gauge by quantities varying 

 from £ inch to f inch in different months, and the total error in ten months 

 amounted to 4|- inches. The cause of the error being obvious, it appeared 

 probable that it might be greatly reduced or even corrected by increasing 

 the depth of the evapometer, and by enlarging the conical cap, which would 

 diminish the evaporation.
