205 and 234, 
The mean of 20" and 23? for the dry bulb thermometer is given as an approximate mean temperature for the month. 
The means for the wet bulb in the month of May 1842 are not strictly comparable with those for the dry 
bulb in the same month, as the readings of the wet bulb for a considerable period in May have been rejected. See
