31 £ Scientific Intelligence. [July,; 



That Mr. West be requested to pursue the experiments contemplated by him 

 into the conbinations 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 phenomena from which the materiality of 

 what are sometimes called ethereal substances has been inferred. 



Miner a logical Committee. 



The Committee recommend, that the Rev. Professor WheweU 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 geoiogists be requested to examine 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-operation 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 engineer, be requested 

 to prepare a report upon the waste and extension 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 that individuals who can furnish observations be requested to 

 correspond with him on the subject. 



Note. — The importance which, especially of late years, has been attached to facts of 

 this 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 acquaintance with 

 the coast in general, and more particularly the minute survey made by him some 

 years since, gives reason to expect from his report much important and accurate 

 information. 



Botanical Committee. 



The Committee recommend, that Professor Lindley be requested to prepare for 

 the next meeting an account of the principal questions recently settled, or at 

 present agitated, in the philosophy of Botany, whether in this country or abroad : 



That botanists in all parts of Great Britain and Ireland be invited to compose 

 and communicate to the meetings of the Association catalogues of county or 

 other local Floras, with indications of those species which have been recently in- 

 troduced, of those which are rare or very local, and of those which thrive, or which 

 have become or are becoming extinct, with such remarks as may be useful towards 

 determining the connection which there may be between the habitats of particular 

 plants, and the nature of the soil and the strata upon which they grow ; with state- 

 ments of the mean winter and summer temperature of the air and water at the 

 highest as well as the lowest elevation at which species occur, the hygrometrieal con- 

 dition of the air, and any other information of an historical, ceconomical, and 

 philosophical nature. 



Note. — If upon this plan a complete botanical survey of the British islands 

 could be obtained, the results would be important when the Flora in the aggregate 

 came to be compared with its relations of soil, climate, elevation, &c.
