It is well to remember in examining the olecranon fossa 
that the partition, if it exists, is often extremely thin and when 
sand or earth is removed with a pointed instrument an 
artificial perforation may result. In the humeri examined by 
me at Tick Island and other burial mounds, data as to which 
are furnished for comparison, all foreign substances were 
removed from the cavity with the aid of a soft brush. It is 
therefore believed that none but pre-existing perforations are 
enumerated.
