5. On the Temperature of Greenland. During the eleven 

 years M. Muller has resided in Greenland, he has only twice 

 heard the sound of thunder, which, repeated by the echoes of 

 the mountains produced, according to him, a most extraordi- 

 nary and unusual noise. At Frederikshaab the temperature 

 of the only spring which existed in the neighbourhood, and 

 which is about half a mile east from the establishment, is 37 

 Fahr., whilst that of the atmosphere is 41. This spring, 

 which is on all sides surrounded with snow, forms a nearly cir- 

 cular basin, from nine to ten feet in circumference, and is about 

 two feet deep. The temperature of the Greenland huts, du- 

 ring summer, varies from 47 to 54 Fahr., according to the 

 number of inmates, and as the lamp is lit or otherwise. The 

 temperature in the open air was 43. The height of one of the 

 highest ice-mountains or islands seen by the Recherche, was 

 found by calculation to be 167 feet : it probably had a double 

 base. 



6. Rapid Fall of the Barometer during the late violent gale 

 on Monday the 19th February 1837 at Edinburgh. The fol- 

 lowing results seem to be remarkable for this latitude. 



Thus in the first hour and quarter the barometer fell .27 of 

 an inch ; in the next quarter of an hour .06 ; arid in two hours 

 and three quarters from nine o'clock the fall \*as .43. The ba- 

 rometer observed is about seventy feet above the level of the 

 sea by barometric measurement. A. Connell. 



7- Red-coloured Sea. On the 1 2th of March (to the north of 

 Cape Pilaris, in South America), precisely at noon, we were not a 

 little alarmed by a considerable noise upon deck, and by the order 

 immediately to lie-to. The dirty red colour of the sea had produc-
