Meteorological Observations. 311 



I have fortunately since discovered my error, and hasten to make 

 the only reparation in my power — that of acknowledging it. 



I can assure Sir David Brewster that there is nothing I regret 

 more than having made, even inadvertently, any misrepresentation, 

 particularly of one whom I must ever look on as one of the fathers 

 of science, and whose opinions, even though they differ from my 

 own, I will ever regard with respect. 



Your obedient Servant, 



Robert T. Foester.
