and the estimated water mean 73°4. c UN a. 
2 The means for the whole month of October 1831, between Dakkeh (latitude 23° 12’) and Gerf Hossayn, 
are 80°4 for the air and 77°4 for the water, the last computed i in part. 
3 The water mean has been estimated by curves, there being only observations for eight days during 
the month. The air observations were continuous.
