1891-92.] Dr D. Turner on Electrical Besistance of Urines. 21 
— T7. The specific resistances of the various urines may therefore 
be approximately found by multiplying the observed resistances 
by T7. 
The specific resistance of a normal urine amounts on the average, 
from my observations, to about 40 ohms. 
Results. 
Put very hriefly, I find that the resistance of a urine varies as a 
rule inversely with the amount of the solids it holds in solution ;
