INSTRUCTIONS. 19 To Order No. PC 16 (2) Customer's No. It might be worth noting that the three condensers which have almost returned to normal, are the oldest that we have, and also those with the lowest initial capacity. On the other hand, the three which have retained their increase, together with No 547 which has fallen slightly, are the latest, and, with the exception of the Bosch, those having the highest initial capacity. As reported in PC 4 / 28-11-23, the only test made since the heating tests, and previous to this last record, was the freezing test, when four of the above condensers, Nos 32, 613, 741 and Bosch, were exposed for about thirty hours (in two periods) to a low temperature, which, generally, had no effect on them.
