DISINFECTION.
Disinfection of Rooms.—2,694 rooms were disinfected, as contrasted
with 1,780 in 1919. For this purpose formaldehyde, either in a gaseous form
or in solution, was employed, although it was sometimes augmented by
sulphur dioxide, when it was necessary to kill vermin, for which purpose it has
been found most effective. For the extermination of bugs, however, all
the architrave mouldings and skirting boards behind which they breed are
removed, and the walls washed with hot lime.
The above figures also include the disinfection of houses and rooms
after Phthisis, vide p. 37.

The following class-rooms, etc., were disinfected after the occurrence in
them of cases of the diseases mentioned:—
1st Quarter. Nil.
2nd Quarter. Nil.
3rd Quarter. Queen's Head Street L.C.C. Schools (Diphtheria).
Hanover Street L.C.C. Schools (Diphtheria).
4th Quarter. Hanover Street L.C.C. Schools (Diphtheria).
Work at the Disinfecting Station.—45,433 large articles of bedding,
etc., as detailed below, were disinfected by the steam disinfectors, at the
Council's Disinfecting Station, compared with 41,336 similar articles disinfected
during the previous year.
In addition to the above articles 98,720 old or second-hand garments,
mostly soldiers' overcoats, jackets, tunics and trousers were disinfected for
clothing contractors trading in the borough, who paid the Council for the work,
amounting to the sum of £145 8s. 5d.
Altogether 144,153 articles described in the two paragraphs preceding
were disinfected, which bring the number of large articles disinfected since
the disinfecting station was established to 1,641,828.
