funnel-shaped for the better mixture and distribution of the steam and
hot air, and to collect any condensation water. Q¹ is a sieve to catch
any fallen article. The vertical tubes, S, which serve at the same
time to strengthen the chamber, connect the lower portion of the steam
jacket, P, with the circular channel, T, which is again connected with
the chimney, M, by the tube, T'. The disinfection chamber is
hermetically closed by the double cover, R, to the lower plate of
which hooks for hanging the sacks are fastened. The cover fits in a
sand bath, and is raised and lowered by means of the pulley chain, W,
and the swinging crane, X. U is a thermometer indicating the
temperature of the steam and hot air in the disinfecting chamber, V a
cock for drawing off any condensation water, Y a battery connected
with an electrical thermometer to be placed in the clothes or bedding,
and Z the sacks in which the infected articles are hung.

The portable apparatus, as shown, for heating with gas, or even
spirits of wine, can also be heated with a similar steam and hot air
apparatus as the stationary disinfector. In country towns or villages,
or even in cities, whose architectural arrangements permit, the
portable disinfector can easily be drawn by one man into the courtyard
or garden of any house, and the process of disinfection conducted on
the spot. Its usefulness in campaigns for ambulance hospitals is
self-evident. The letters denoting the several parts are the same as
in the stationary apparatus. The portable disinfector is constructed
to disinfect two complete suits of clothes or one mattress. The
extremely favorable results are shown in the accompanying table of
trials.--_The Engineer._
