METEOROLOGY 375 



merciful to delicate instruments. Its clockwork had not been 

 cleaned before it was sent to the Fram, as was done in the case of 

 the other four instruments. The barographs worked irreproach- 

 ably the whole time, but one of the thermographs refused abso- 

 lutely to work in the open air, and unfortunately the spindle pivot 

 of the other broke as early as April 17. At first the clockwork of 

 the hygrograph would not go at all, as the oil had become thick, 

 and it was not until this had been removed by prolonged severe 

 heating (baking in the oven for several days) that it could be set 

 going; but then it had to be used for the thermograph, the 

 mechanism of which was broken, so that no registration was 

 obtained of the humidity of the air. 



The resulting registrations are then as follows : from Framheim, 

 one set of barograms and two sets of thermograms, of which one 

 gives the temperature of the air and the other the temperature 

 inside the house, where the barometers and barograph were placed; 

 from the Fram we have barograms for the whole period from her 

 leaving Christiania, in 1910, to her arrival at Buenos Aires for the 

 third time, in 1912. 



Of course, none of these registrations can be taken into account 

 in the provisional working out, as they will require many months' 

 work, which, moreover, cannot be carried out with advantage until 

 we have ascertained about possible changes of error in the instru- 

 ments. But occasional use has been made of them for purposes of 

 checking, and for supplying the only observation missing in the 

 ten months. 



The meteorological station at Framheim was arranged in this 

 way : the barometers, barograph, and one thermograph hung inside 

 the house; they were placed in the kitchen, behind the door of the 

 living-room, which usually stood open, and thus protected them 

 from the radiant heat of the range. A thermometer, a hygrometer, 

 and the other thermograph were placed in a screen on high posts, 

 and with louvred sides, which stood at a distance of fifteen yards to 

 the south-west of the house. A little way beyond the screen.
