374 APPENDIX II 



Toluene thermometers: 



Eighteen sHng thermometers, divided to degrees. 

 Three normal thermometers — by Tounelot, No. 4,993, and 

 Baudin, Nos. 14,803 and 14,804. 



Two torsion hair hygrometers of Russeltvedt's construction, 

 Nos. 12 and 14. 



One cup and cross anemometer of Professor Mohn's construc- 

 tion, with spare cross. 



One complete set of precipitation gauges, with Nipher's shield, 

 gauges for snow density, etc. 



Registering instruments: 



Two barographs. 

 Two thermographs. 

 One hair hygrograph. 



A number of spare parts, and a supply of paper and ink 

 for seven years. 



In addition, various books were taken, such as Mohn's "Meteorol- 

 ogy," the Meteorological Institute's "Guide," psychrometric tables, 

 Wiebe's steam-pressure tables for hypsometer observations, etc. 



The marine barometer, the large aneroid, and one of the 

 barographs, the four mercury sling thermometers, and two whole- 

 degree standard thermometers, were kept on board the Frayyi, 

 where they were used for the regular observations every four hours 

 on the vessel's long voyages backwards and forwards. 



As will be seen, the shore party was thus left without mercury 

 sling thermometers, besides having no minimum thermometers; the 

 three maximum thermometers proved to be of little use. There 

 were also various defects in the clockwork of the registering instru- 

 ments. The barographs and thermographs have been used on all 

 the Norwegian Polar expeditions; the hygrograph is also an old 

 instrument, which, in the course of its career, has worked for over 

 ten years in Christiania, where the atmosphere is by no means
