On the other hand five correspondent- recommended 25° 

 as a more suitable temperature, one suggested 28°, another 

 M 5 , and a worker in Madras informed the Committee that he 

 had already adopted 33°. Many valuable observations and 

 suggestions were made by the correspondents, which we have 

 endeavoured to summarise. It is noticed that the most 

 interesting replies are from those who do not favour the immediate 

 adoption of the Committee's proposal : these are from physicists. 

 Ao chemist records his opinion in favour of the adoption of a 

 lower temperature than 30°.

 Z. Inese temperatures are taken in open sheds (con- 



cations laid down by the Meteorological Depart- 

 ment), which are much hotter than our laborato- 

 ries. 



3. Most of our serious research work must be done during 



the winter months, and a mean winter temperature 

 would consequently be more convenient than a 

 mean yearly temperature. I would suggest 25° as a
