‘A generally similar pattern was observed in
these analyses for all four components. Thevariation among years was alwayshighly significant,
largely because of an increased countin all four
components in 1964. This annual difference has
been commented on in previousreports. Differences
existed in 1961, 1962, and 1963, but these were

not chronologically consistent among the com-
