The Meteorological Committee iias been engaged in pre- 

 paring a general plan of observations on atmospheric pheno- 

 mena, which they hope to cause to be executed at many stations 

 contemporaneously, so as speedily to determine the principal 

 elements of the local climate of Yorkshire. To effect this 

 desirable combination of results, it was required not only to 

 propose a good plan, but to prove its practicability with the 

 ordinary means and activity of a provincial Society or the 

 leisure of insulated observers. They have, therefore, been 

 diligently employed in determining one of the most difficult of 

 all the problems to be solved by their proposed scheme of 

 observations, viz. the oscillations of the barometer at several 

 hours of the day. The observations on this subject have been 

 personally executed by the Secretaries so as to give results 

 oither exact or approximate for the last fifteen months, as 

 expressed in the following table, where all the mean results 

 are compared with the standard observation at 9, a. m. and 

 the differences, to thousandths of an inch, in excess or defect, 

 jnarked by the signs + and — .
