The observed period changes of a pulsating variable star can, in principle, provide a sensitive test of the movement of the variable through the instability strip of the HR diagram. We revisit the long term period behavior of variables V42 and V84 in M5, making use of new BVI light curves of these type II Cepheids. V42 has shown a small decrease in period since 1889. The period changes of V84 are more difficult to ascertain, with possible short term changes in the observed phase of maximum light. The observed period changes, in both cases based upon observations spanning more than a century, are consistent with the earlier determinations of Coutts Clement & Sawyer Hogg (1977, JRASC, 71, 281).
