*' Report of the Committee on the Instruments for the 

 Measurement of Earthquake Waves" was given in. 



" Report of the Meteorology of the Azores," by Mr J. C. 

 Hunt, communicated by Col. Reid, was laid before the meet-

Dr Martins addressed the meeting in French, " On the 



six Climates of France." — He commenced by stating, that 

 France partook of the climates both of continental and sea- 

 girt countries. He wished at present to consider six clima- 

 toreal subdivisions, viz., — 1. The North-east or Vosgien. — 

 2. The North-west of Sequanien.— 3. That of the West or 

 Armoricain. — 4. The South-west or Girondin. — 5. The South- 

 east or Rhodanien. — 6, and finally, the Mediterranean or 

 Proven9al climate. Upon each of these subdivisions he en- 

 larged ; detailing the features of the country, the rivers, 

 mountain-ranges, sea-coasts, geological structure, differences 

 of level, and state of cultivation in each case, with the pre- 

 vailing and most important features in the actual climate of 

 each. Dr Martins exhibited a map of France with these six 

 regions distinguished. He stated, that hitherto the labours 

 of the Meteorologists of France had no channel of publicity 

 at their command, but that a journal devoted exclusively to 

 Meteorology was about to be established. 



Dr Lee made a communication '* On the Meteorological 

 Register kept at Alten and Christiania — and some Observa- 

 tions on the British Meteorological Society." 



*' The Report of a Committee appointed to examine the 

 Effects produced by Lightning on a Tree near Edinburgh," 

 was read by Professor Phillips. — The tree in question stands in 

 the grounds of Mr Wauchope, at Edmon stogie, about four miles 

 from Edinburgh, on the Dalkeith road. The surface slopes 

 gently to the north; thesubstrata arepartof the coal formation, 

 and contain at a small depth an abundance of the rich " black 

 band" ironstone. The locality appears remarkably liable to
