Meteorological Observations at Melville Island, 



Abstract of the Register of theThermometer and Barometer du- 

 ring ten months, at Winter Harbour, Melville Island, North 

 Georgia, 1819 and 1820. 



Latitude 74° 4/' 18", Longitude 1 10" 48' 30" W. 



Remarks. — The thermometer was fixed, during the winter, on the south 

 side of a david projecting from the ship's side, and was usually from 3" to 6' 

 higher than one suspended freely in the air at a distance from the ship. 

 This difference increased as the summer advanced, and the sun rose suffi- 

 ciently al)ove the horizon to heat the ship, amounting latterly to 15" or even 

 20"^ about noon. The thermometer was, of course, always shifted to the 

 shaded side uf the ship or david. 



On the 1 5th of February, at 6 P.M., a thermometer suspended 

 freely in the air at a distance from the ship stood at — 55°, being 

 tiie lowest degree registered during the winter. 



The very low temperatures were invariably in calm and clear 

 weather; the rise of the thermometer being the immediate con- 

 .sequence of a breeze springing up, and being proportioned to its 

 strength. 



The barometer rose with northerly and r.esterly, and fell with 

 southerly and easterly winds; but it was not so decided that the 

 indications preceded the changes, as it is stated to be in more 

 feouthcrn climates. — Journal nj' Science, No. 21.
