Col. Sykes appears to consider Glaisker's and other Tables, for 

 deducing the DewPt. from the difference of the dry and wet bulbs 

 as very imperfect. The above results do not show error, nor have 

 I found any very material error in any other observations which I 

 possess except, perhaps, in very extreme cases.
