It will be noted that Pitchford's figures (Table i) are from 

 40 times to well over 100 times as high as ours. Thus for the 

 urines passed ten hours, after dipping, his figures range from 

 .028 per cent, to .097 per cent. As^Oa. and ours from .0005 to 

 .0009 per cent. The discrepancy requires elucidation. We hope 

 to return to this at a later date and offer more detailed figures
