 this the results differ from those of Series VI, which being longer con- 

 tinued and including a greater number of men must be given more 

 weight in the final conclusions. The data indicate a. slight but per- 

 sistent disturbance of nitrogen metabolism, which can only be regarded 

 as having a prejudicial effect upon health.
