Observations on the Collation of Measurements 



It must be acknowledged that the results obtained by the measurement 

 of skulls have not met the expectation of those who have made them. The 

 average measurement is often inadequate as a means of expression of general 

 conclusions. I venture to propose a method of treatment of the figures which 

 appears to me to have advantages over mere summation or the securance of 

 averages, an arrangement which will include all the numbers of a given 

 series in order from the minimum to the maximum, and which will indicate 

 precisely those measurements most frequently recurring as well as those 

 which are absent. I will illustrate my meaning by reference to the measure- 

 ments of the Interorbital Width, because this is subject to the least amount of 

 variation. The figures as copied from the table are as follows : 



These figures when arranged with the maximum number at the top and 

 the minimum at the bottom, and grouped as indicated by braces, are herewith 

 given :
