with platinum wire of the same kind as that used in the present 
instance 
wi = w, (1 + 0.003864 t — 0.0,103 #°) 
thus to = — 182°.99. 
The calculation of the temperatures of the projecting portions from 
the values wag and wep will be described in § 4. 
In the following table the final results*) for all the determinations 
are given, the standard scale at 16° C. being taken as the reference 
length. Column / thus contains the values for the rod lengths reduced 
to this reference. We have used as the expansion coefficient of 
brass between 16° and 17° the value 17.8 10-6. Column / refers 
to the ends, and its contents will be considered in § 4.

1) The numerical values are slightly different from the values given in the original 
Dutch paper according to a new and more exact calculation. The final results 
for the dilatation given in the original are quoted § 6 footnote.
