1 Physics. - Establishment f an Abslute Scale fr the herm-electric Frce. By G. BOR ELlUS. W. H. KEESOM. C. H. JOHANSSON and J. O. LND E. Supplement N0. 69b t the Cmmunicatins frm the Physical Labratry at Leiden. (Cmmunicated at the meeting f January ) he results btained fr the therm-e1ectric frces f Pb and Sn at liquid helium temperatures and higher 1) tgether with the assumptin made prbable by thse results. that the HOMSON-heat a is zer in the supracnducting state 2). render the establishment f an abslute scale fr therm-e1ectric frces pssible. he H OMSON thery gives the frmula de al dy which n accunt f the N ERNS therem gives?y integratin ' e=.[~ d-.[id. (2) 0 he integrals may be called the abslute therm-e1ectric frces per degree fr each f the tw metals. and they are f curse f mre interest than the therm-electric frce f the cupe. t is bvius frm (2) tha t if the integral is knwn fr ne metal. it may he determined fr any ther metal at any temperature by measurement f the therm-electric frce against the first. get the value f the integral fr that ne metal. it is. hwever. necessary t knw the values f al cntinuusly frm dwn t the lwest temperatures. Frtunately the measurements seem t give such a knwledge with a fairly gd degree f accuracy. Belw the critical pint f Sn at K al is by assumptin zer fr Sn as weil as fr Pb. Frm 3.72 t K it is zer fr Pb. and may be calculated fr Sn and fr the special silverally wire called "nrmal" in the Cmmunicatin mentined 3) by the aid f equatin (1) frm the thermc1ectric frces against Pb. Abve 20 0 K al is knwn fr the nrmal frm the direct measurements f the HOMSON heat made by BOR ELlUS. KEESOM and JOHA NSSON 4) and may be calculated fr Pb and Sn fr m thc measurements f Cmm. N. 217c.

As will be seen frm the diagram in the case f Sn the gap can. hwever. quite easily be filled up by cnnecting the curves n its sides. As t Pb and the nrmal the shape f the curves between 7.2 and 20 is rather unfit fr a graphical interplatin. he dtted lines in the figure were derived frm the therm-electric frces against Sn accrding t equatin (1). At the critical pints the curves are simply drawn as if there were a discntinuity in defd. thugh in fact we nly knw. thilt there is a rapid change. As hwever the curves are btained here by graphical derivatin this detail will have n influence n the result f the ABLE. Numerical values t Fig. J. OK.
