indicatiuo- an actual shrinking of the water, that the fact of its 

 beino- hi a state of progressive diminution appears to be now 

 ascertained almost beyond dispute. In the course of the years 

 18-^0 and IS*^! M. N. Bruncrona, with the assistance ot the 

 officers of the Piloting Establishment, and of other individuals 

 familiarly acquainted with the subject, undertook an examina- 

 tion of all tlie well-autlienticated watermarks which have been 

 made alono- the western shore of the Baltic within the last half 

 century His results, which are in the fullest extent conhrma- 

 toryof the conclusions which had been deduced by pi-eceding 

 observers are consigned in a short memoir in the Swedish|lrans- 

 actions for 1823. The following table exhibits the amount to 

 which, according to his observations, the level of the water has 

 fallen within the last forty years. It is necessary to remark, 

 that, in some instances, the watermarks were much older, and, 

 in others, of a more recent date than forty years : in all such 

 cases, the change which had taken place withm the last forty 

 years was estimated by calculating the mean annual depression 

 'from the period of the earliest observation.
