14 C. Barns — Change of Heat Conductivity, etc. 



17. Digest. — My data for k have been summarized in Table 

 4. In constructing mean values for k, for each heating, data 

 below 10°= 8 are usually discarded, because in these cases the 

 correction factor m can no longer be found without difficulty 

 in view of the rapid variation of q. The table also contains 

 the mean values for thermometric conductivity (x = k/pc) 

 obtained (§15) by putting for the liquid at 13°, pc =-4:53, and 

 for the solid at 12° and at 11°, pc = *334 and - 333 respectively r 

 with the corresponding mean k for each spacing, A.
