Resolved to report to the Council for submission to the next 

 Ordinary General Meeting under Rule 48 (a). 



The General Secretary also laid on the table the following 



Report of the Standard Temperature Committee submitted by 

 Mr. D. Hooper, the Secretary of the Committee : 



At the Meeting of the Asiatic Society of Bengal held in 

 July 1908, Professor P. Briihl read a paper on " Proposals for a 

 Standard Temperature for Tropical Climates." The author 

 pointed out that the normal temperature of 62°F. does not serve 

 the purposes of the chemist and physicist who work in the tro- 

 pics, and the spread of science will render the choice of one or 

 more higher standard temperatures a matter of necessity. The 

 author's observations led to the conclusion that the most 

 convenient standard temperature for Calcutta is 30°C. (86°F.), at 

 least during the period extending from the middle of March to 

 the middle of November. During the remaining part of the year 

 22°C. (7r6°F.) would be more useful. During the discussion 

 that ensued it was advanced that 25°C. (77°F.) was a suitable 

 temperature for Calcutta. A resolution was finally passed that 

 the question of a standard temperature for India be referred 

 for report to a committee of scientists to be selected by the 

 Asiatic Society of Bengal. 



The Council appointed the following to serve on the 

 Committee : — 



Dr. Morris Travel-, Bangalore, Chairman.

The Committee met in December and proceeded to discuss 

 the form of note to he sent to chemists and physicists through- 

 out India. It was proposed to circulate Prof< >or Briihl' 8 



paper and invite opinions on the proposals. In the covering 

 letter the Committee recommended a change in the standard 



temperature observed in Europe and suggested 30°C. a^ most 

 suitable for India. Expressions of opinion were called for, 

 and the Committee asked to be supplied with the results of 



calculations or experiments connected with thermo-t -.instants 



in India.

 ence for India. These came from the following towns and
