Meteorological Observations. 79 



M. Kestner states that he is informed that Mr. Whyte, a manu- 

 facturer of tartaric acid at Glasgow, has also produced paratartaric 

 acid. He regrets that he is unable to say more on the subject, and 

 shall be happy if science should put him in the way of reproducing 

 this interesting acid. — L'Institut, Novembre 14, 1849.
