the number a convenient size. In testing the standard we 

 get 118 under the fifth column, and so we must multiply all 

 results by \V* to reduce them to a common basis so that 

 they can be compared with any other series of tests. The 

 rest of the table needs no remark, except, perhaps, the last 

 column, where the hardness in the three directions are 

 given relatively to each other. 



In Table II we have the timbers given with their various 

 hardness in the three different directions. From this table 

 Table III is made up, which just gives the timbers arranged 

 in order of hardness in the three directions, O, B and A. 

 If we add the three numbers which represent their positions 

 in descending order in each table, we can find their order
