index descended towards dryness, and ascended towards moisture; 

 m the present instrument the motions are reversed, so that its 

 action is rendered more conformable to that of the barometer 

 and thermometer. 



We have an account of the observations that were made in 

 this meteorological observatory during the latter half of Sept. 

 1817. 



The greatest height of the barometer 22*40 



The least height 22*06 



The mean height at sun-rise 22-36 



Ditto at 2 P.M 22-42 



The greatest height of the thermometer . . . 54*5° 



The least height 29-75 



Mean height of the thermometer at sun-rise 38-00 



Ditto at 2 P.M 46-6 



Mean height of the hygrometer at sun-rise . , 92-0 

 Ditto at 2 P.M 84-3 



There were four rainy days during this period ; the quantity of 

 rain was no more than -7 inch : the season is represented as 

 having been peculiarly fine. 



XII. Researches on the Cerealia. By M. Vogel. 



M. Vogel read a memoir on this subject to the Royal Aca- 

 demy of Sciences at Munich, in March last ; the following are 

 the principal results which he deduces from his experiments ; but 

 the processes are not detailed by which they were obtained.
