the hot water collected from the coil drains, where the
latent heat of the steam has already been abstracted by
the evaporator tubes, but which has still left the sensible
heat that the steam had. These are led into the top pipe
(A) over the heaters. The first two, (1) and (2), being
steam, give out their latent heat to the feed-water as such

steam passes down into the tubes of the heater, and the
waters of (3), together with any steam that may have
escaped through the coil drain, and all three, (1), (2),
and (3), after thus imparting their heat to the feed-
water surrounding the tubes, are collected in the
lower pipe (B), and then gravitate into the distiller
tubes.
