Chandler-The Inter- Generation Period. it is evidnet that the first and the last of the ten generations are sadly incomplete; and, if these be omitted, the mean period rises to 32.1. In the preparation of this paper considerable search has been made for lines extending through a larger number of generations than any that are here shown, but it has had very indifferent success. Such lines of descent, when claimed for families of the commonalty, usually present doubtful points of connection, and rest under suspicion of being due to more or less of ingenious fabrication; and, while royal and noble lines are to be found, such lines of course are generally along the older branches of the family, and so give a period much shorter than the true one, although the tendency in such lines to follow descent through sons counteracts this in part. The line from William the Con- queror to Queen Victoria offers an illustration. It covers twenty-five or twenty-seven periods, according to the ancestral line which is followed, and gives a mean period of 31.7 or 29.3 years. Perhaps a fair summary of the results of the work presented in this paper may be thus stated. The more nearly complete the record of births in each generation and the greater the num- ber of generations included in the examination, apparently the greater is the tendency to a mean period of one-third of a cen- tury.
