134 ON THE CALCULATION OF THE CONDUCTIVITY 
acids. Kohlrausch’s latest determinations’ of the values of the 
specific molecular conductivity at infinite dilution at 18° C. for 
the two acids were used, viz.: for hydrochloric acid, 3774, and. 
for sulphuric acid, 3955, both expressed in terms of 107* times 
Kohlrausch’s new unit (ohm cm. *). Therefore, the ratio is 
1.048. 
Table I gives the data, obtained from the conductivity 
observations, for the drawing of these curves. The concentra- 
tions are expressed in terms of gramme equivalent per litre 
at 18°C. The atomic weights used are relative to Oxygen 
(16.00), and the same as employed by ?Kohlrausch. The specifie 
conductivities are those at 18°C, expressed in terms of 107* times 
Kohlrausch’s new unit (ohm? em.~’).
