The values for the electrical conductivity have been measured 

 downwards in the above diagram to render them more easily

 Diagram showing relation between various properties and constituents of 

 cows' milk. Ordinates : values of quantities measured. Points on 

 abscissa represent corresponding values of different quantities. 



The diagram show^s, at once, that there is a distinct, inverse 

 relation between the mean percentage of lactose, and the mean 

 conductivity. Jackson and Rothera (1914) showed that a similar
