Actually the pairs of tuberculous mates observed are 

 rather less than double the chance number of such 

 pairs. The correlation has fallen to o-i6. In Table III

we have Goring's results for tuberculosis in husband 

 and wife for the poor of all classes — the distribution 

 actually observed is to a unit the same as the chance 

 distribution — the correlation is zero, or there appears to 

 be no greater chance of the mate of a tuberculous person 

 being tuberculous than of any other person. There 

 appears to be matter here to lead us to pause. As we go
