Table 241. 



CORRECTION FOR TEMPERATURE OF MERCURY IN THERMOMETER 



STEM. 



* This table is quoted from Rimbach's results, "Zeit. fiir Instrumentenkunde," vol. lo, p. 153. The numbers 

 represent the correction made by direct experiment for thermometers of Jena glass graduated from 0° to 360° C, 

 the degrees being from i to 1.6 mm. long. The first column gives the length of the mercury in the part of the stem 

 which is exposed in the air, and the headings under / — /' give the difference between the observed temperature and 

 that of the air.
