“Moisture in ore going to #1 Stockhouse 1 [40/100?] of 1%.” 
“Ore going into #1 Stockhouse 45% below 50 mesh.” 
Mr. Edison does not understand the first of the statements quoted above. Does it mean that the moisture contained in the ore going to #1 Stockhouse is 1% and 40/100 of one per cent? Please explain. Regarding the second statement, Mr. Edison wishes to know if 55% of the ore going into #1 Stockhouse is above 50 mesh. 
Please reply promptly.
