( 3824 33824 ) ) , so that in the example given where the percentage increased to 40.8 per cent in one hundred pounds of the solution there would be ( ap- ap ) proximately 40 per cent of sand and sediment and 60 per cent of water . He has no other figures as to floods , but he has calculations of the total load for that period or for any of the periods . ( R .
