XXXvi THIRD REPORT — 18,33. 



in the Reports published by the Association, or from sugges- 

 tions made at the present Meeting, they may think most fit to 

 be advanced by an application of the funds of the Society, 

 either in compensation for labour, or in defraying the expense 

 of apparatus, or otherwise. The Committee are requested to 

 confine their selections to definite as well as important objects ; 

 to state their reasons for the selection, and where they may 

 think proper, to designate individuals to undertake the desired 

 investigations ; they are to transmit their Recommendations 

 through their Secretaries to the General Committee. 



The Committees of Sciences having complied with these in- 

 structions, the following Resolutions were passed by the General 

 Committee : 



1. That a sum not exceeding 200/. be devoted to the dis- 

 cussion of observations of the Tides, and the formation of Tide 

 Tables, under the superintendence of Mr. Baily, Mr. Lubbock, 

 Rev. G. Peacock, and Rev. W. Whewell. 



2. That a sum not exceeding 50/. be appropriated to the 

 construction of a Telescopic Lens, or Lenses, out of Rock Salt, 

 under the direction of Sir David Brewster. 



S. That Dr. Dalton and Dr. Prout be requested to institute 

 experiments on the specific gravities of Oxygen, Hydrogen, and 

 Carbonic Acid ; and that a sum not exceeding 50/. be appropri- 

 ated to defray the expense of any apparatus which may be re- 

 quired. 



4. That a series of experiments on the effects of long con- 

 tinued Heat be instituted at some iron furnace, or in any other 

 suitable situation ; and that a sum not exceeding 50/. be placed 

 at the disposal of a Sub-Committee, consisting of Professor 

 Daubeny, Rev. W. V. Harcourt, Professor Sedgwick, and Pro- 

 fessor Turner, to meet any expense which may be incurred *. 



5. That measurements should be made, and the necessary 

 data procured, to determine the question of the permanence or 

 change of the relative Level of Sea and Land on the coasts of 

 Great Britain and Ireland ; and that for this purpose a sum 

 not exceeding 100/. be placed at the disposal of a Sub-Com- 

 mittee, consisting of Mr. Greenough, Mr. Lubbock, Mr. G. 

 Rennie, Professor Sedgwick, Mr. Stevenson, and Rev. W. 

 Whewell ; — the measurements to be so executed, as to furnish 

 the means of reference in future times, not only as to the re- 

 lative levels of the land and sea, but also as to waste or exten- 

 sion of the land. 



• These experiments have been instituted by Mr. Harcourt, in Yorkshire, at
