 The records have been checked and brought down to date 

 by Prof. Sherer. 



The observations from 1865 to 1869 were made by Prof. Acker- 

 mann and ])ul)lished in the Jahrbiicher der k. k. Zentral- 

 .Anstalt fiir Meteorologie and (ieodynamik. Wien, 1893 and 

 also in Proceedings of the American I'hilosophical Society.

The height of the barometer from 1888 to if;o7 was 37.0 m. 

 (owing to faulty measurements the height was given too 

 low in the early pul)lications ) . In 1908 the height was 

 changed to 37.4 m. and remained at that level up to 1925. 

 The means given are those derived from observations at 7''. 

 13*^ and 21''. To correct these means t<) 24 hour means 

 apply the following corrections :

The pressure readings were corrected for temperature and a cor- 

 rection of —1.57 was applied to reduce to gravity at 45^

The hours of observations wei^e the same as those for pressure 

 and the means are ] ( 7'^ + 1 3'' + 2 1 '' + 2 1 'M • 

 Precipitation. 



The precipitation records arc in millimeters and oI)tained from 

 the same sources as those of pressure and temperature.
