The largest valuescorresponding to the largest values of D when repeated seldom differed bymore than that, and sometimes the agreement was much closer. If thesame order of error is assumed in the least values of W, which are a smallfraction (generally about one-third or one-fourth) of the greatest values, thevalues of w, which depend on the difference of greatest and least values,would have a rather greater error-limit, 7 or 8 per cent., or even more ina few cases. Declitctions from TcMe I that are Independent of Theory. If the values of wlp> given in the table are plotted against the corre-;sponding values of Y/p, the points so obtained determine a simple continuouscurve. This is shown in fig. 4. 162 Eev. P. J. Kirkby. Chemical Action of the [Oct. 13, Ft9. 4. 50 It follows that lujp is a function of Y/p, and that the relation betweenthese two variables is independent of the current, for the current was arbitraryand varied by several hundred per cent., while the points plotted in fig. 4fall upon the curve within the limits of experimental error. This result proves definitely that the observed chemical effects in thepositive column are not directly due to recombination* of ions, for thenumber of recombinations per cubic centimetre would increase with thesquare of the current, since the force and therefore the velocity of the ionsare very little affected by the current. It also proves that these chemical effects are not due to any internalradiation, such as perhaps the entladungstrahlen, set up in the positivecolumn by the recombination of ions, for the intensity of such a radiationwould probably be proportional to the squaref of the current, and certainlycould no
