of those interested in the promotion of scientific pursuits ; and 

 adds : " If there is any Committee in whose work your Society, or 

 individual members thereof, would be willing to render assistance, 

 please communicate with the Secretary of the Committee, or with 

 the Secretary of the Association," at 22 Albemarle Street, Lon- 

 don, W. 



From the above Report and List we extract such information 

 regarding the various Committees whose operations include Scot- 

 land as will be sufficient to indicate to anyone willing to give 

 assistance in what way such assistance can be most usefully given. 



We shall also notice those Committees whose work, though at 

 present restricted to other parts of the United Kingdom, might 

 very advantageously be extended to Scotland, or might be inde- 

 pendently taken up by the Scientific Societies in Scotland on 

 similar lines. 



The various Committees are grouped under the Sections of the 

 B.A. to which they belong; and those for which a grant of money 

 has been voted have the amount stated between brackets. The 

 name of the Secretary of each Committee is also given below. 



Section A. 



1 . Seasonal Variations in the Temperatures of Lakes, 

 Rivers, and Estuaries in various parts of the 

 United Kingdom, (Sec. Dr. H. R. Mill). Dr. Mill ex- 

 plained to the Conference of Delegates that the object is 

 to accumulate as great a mass of data with regard to the 

 temperature of the surface of lakes, rivers, and estuaries, 

 and of the sea near its shores, as could possibly be ob- 

 tained, in order to discuss this in connection with the 

 meteorology of the country ; and that it was therefore 

 desirable to have the work undertaken as widely, and under 

 as varied conditions, as possible. As a result of circulars 

 issued to the Corresponding Societies there had been twenty- 

 four sets of observations obtained in England, twenty-one in 

 Scotland, eleven in Ireland, and one in the Isle of Man. 

 The success of the research depends entirely on the extent 

 and care with which the various observers do the work ; 

 and Dr. Mill will gladly give all needful information to 

 any one willing and able to make the observations.
