 burgh, a project which my scientific cruises in the North Atlantic 

 had suggested and preliminary experiments have matured. The 

 importance of meteorological observations is now universally recog- 

 nised, and a continually increasing number of centres of observation 

 are being created in order to assist the progress of this science. 



I proposed to establish on the Azores an advanced post, whose 

 mission should be : 1st, to observe the birth of certain atmospheric 

 disturbances, which appear to .be formed in this region of the 

 Atlantic; 2nd, to correct the path of certain others which appear to 

 threaten the coasts of Europe and which are announced from 

 America at too great a distance of time and space for there to be an 

 assurance that more or less considerable modifications may not take 

 place which will affect their strength, their direction, and the date of 

 their arrival on the European coasts. 



We should then have, on a point situated almost in the middle of
