that "an increase of temperature, other things being equal, 

 aggravates the poisonous action of the sulphurous acid in the 

 air, a difference of a few degrees of temperature being apparent," 

 Dr. Miiller observed that one cause of this would be probably 

 due to the fact that sulphurous acid is converted into sulphuric 

 by an elevation of temperature. With reference to temperatures, 

 Mr. Dyer remarked on the importance of keeping the tempera- 

 ture of houses as low as possible at night compatible with the 

 limits of resistance peculiar to the plants themselves, allowing 

 for some kinds which are peculiarly sensitive ; as a rule, gardeners 

 are apt to keep the temperature higher than is desirable. Mr. 

 Henslow observed that the late Dr. Lindley was continually 

 advocating the same procedure. The thanks of the Committee 

 were tendered to Dr. Oliver for the trouble he had undertaken in 

 preparing the report.
