part of the newer or tertiary formations, and are evidences of 

 the last geological changes that the surface of our globe has 

 experienced, always excepting volcanic and alluvial still in 

 daily operation. 



Of the genus mastodon there are two distinct species, viz. 

 the M. giganteum, and the M. angustidens, distinguished, as 

 the names imply, by the size and by the configuration of the 

 teeth. Our animal belongs to the former species, of which 

 portions of many individuals have been found on our conti- 

 nent, and a few comparatively in Europe. The beauty and 

 value of these organic remains induced us to present them to 

 the Lyceum of Natural History of New York ; and we have 

 the satisfaction of knowing that they constitute an important 

 addition to the fine collection of fossils in the cabinet of that 

 valuable institution. 



Art. 'KVlh'^Observations on the Minimum and Maximum 

 of the Barometer, made during a period of twenty-nine 

 years at Malmanger, and Ullensvang in Norway. By Pro- 

 vost Hertzberg of Ullensvang. * 



The following series of valuable observations of the minimum 

 and maximum of the barometer were taken by Mr Hertzberg, 

 Provost of Hardanger, and Pastor of Kingsverig, in Norway, 

 in the diocese of Bergen. They include a period of twenty- 

 nine years, from 1798 to 1827. From 1798 to 1807, the ob- 

 servations were made at Malmanger, in the diocese of Bergen, 

 in lat. 60° north, and at the height of QQ Rhinland feet above 

 the level of the sea. From 1807 to 1827, the observations 

 were made at Ullensvang, in the same diocese, in the latitude 

 of 60° 19', and at the height of 32 Rhinland feet above the 

 level of the sea. The height of the barometer, which is given 

 in French feet, is reduced to the temperature of 0° of Reau- 

 mur's scale. The temperature in Reaumur's scale is added, 

 and also the state of the weather. 



• This excellent observer has also communicated to us a raluable set 

 % of hourly observations made at Ullensvang on the 15th January 1827.— Ed.
