chemists in general, be invited to make experiments on these sub- 

 jects, and communicate their results to the next meeting at Oxford. 



That Mr. Johnston be requested to present to the next meeting a 

 view of the recent progress of Chemical science, especially in foreign 

 countries. 



That Dr. Daubeny be requested to undertake an investigation into 

 the sources from which organic bodies derive their fixed principles. 



That Mr. Johnston be requested to undertake the inquiries which 

 have been suggested to the Committee into the comparative analy- 

 sis of iron in the different stages of its manufacture. 



That Mr. West be requested to pursue the experiments contem- 

 plated by him into the combinations of gaseous bodies when passed 

 through heated tubes. 



That the Rev. W. Vernon Harcourt be requested to prosecute 

 the inquiries contemplated by him into the chemical phsenomena 

 from which the materiality of what are sometimes called ethereal 

 substances has been inferred. 



Mineralogical Committee. 



The Committee recommend, that the Rev. ProfessorWhewell be 

 requested to present to the next meeting a report on the state and 

 progress of Mineralogy. 



Geological and Geographical Committee, 



The Committee recommend, that geologists be requested to ex- 

 amine strictly into the truth of that part of the theory of M. Elie de 

 Beaumont, in its application to England, Scotland, and Ireland, 

 which asserts that the lines of disturbance of the strata assignable 

 to the same age are parallel, and that a report to the next meeting 

 on this subject should be procured : 



That Mr. Phillips be requested to draw up, with such co-opera- 

 tion as he may procure, a systematic catalogue of all the organized 

 fossils of Great Britain and Ireland, hitherto described, with such 

 new species as he may have an opportunity of accurately examining, 

 with notices of their localities and geological relations. 



The Committee propose, that Mr. Robert Stevenson, civil en- 

 gineer, be requested to prepare a report upon the waste and exten- 

 sion of the land on the east coast of Britain, and the question of the 

 permanence of the relative level of the sea and land ; and chat indi- 

 viduals who can furnish observations be requested to correspond 

 with him on the subject*. 



The importancewhich,especially of late years, has been attached 

 to facts of tills nature, in illustration of the sciences of hydrography 

 and geology, and the mass of uncombined materials which have 

 recently been accumulating, have induced the Committee to make 

 the present recommendation ; and in doing so it feels pleasure in 

 being able to have in its view an individual whose practical acquaint- 

 ance with the coast in general, and more particularly the minute
