The data for the separate years were also grouped into 3- month periods, and graphs plotted for inspection (not repro- duced).

In 6 cases out of 7, there was a well-marked fall from the first to the second period, just as in the lot as a whole (Fig. 2). In 6 cases out of 7, likewise, there was a rise from the second to the third period. In only 3 cases out of 7, however, was there a fall from the third period to the fourth, one line re- maining horizontal and the other three rising. (One of these last is based upon only 19 individuals.).
