SECTION H
DISEASES OF ANIMALS
Throughout the year, the Borough remained free from any
outbreaks of notifiable disease.
There was an outbreak of foot and mouth disease at Bedfont,
Middlesex, on 7th March and the Borough was included in the
infected area which was made round the infected place. This inclusion
automatically imposed restrictions on the movement of animals
into the Borough and all movements had to be licenced. The
restrictions were removed on 22nd March by which date a total of
4,850 animals had been moved into the Borough on licence.
SECTION J
ATMOSPHERIC POLLUTION
There has been no change in the siting or in respect of the
recording of the three deposit gauge and seven lead peroxide
stations and analyses have been maintained throughout the year.
ESTIMATION OF ATMOSPHERIC SULPHUR BY THE
LEAD PEROXIDE METHOD
The monthly figures for each station for the years 1953 and
1954 are shown statistically and graphically on pages 46 and 47.
Again the yearly average figure—2.2—shows an increase over that
of the previous year.
The station with the highest monthly figure—4.53—and the
highest average figure—2.58—was that at Bashley Road. The
station with the lowest monthly figure—1.90—and the lowest
average figure—0.68—was that at Acacia Road.
DEPOSIT GAUGES
The monthly figures for each station are shown statistically
and graphically on pages 48 and 47. The average monthly rainfall
is shown in the table on page 48.
The yearly average figure—22.74 tons/square mile—shows
a further slight increase over that of the previous year but there
was a very slight reductio in the amount of combustible matter in
the deposit.
The station with the highest monthly figure—45.36 tons/sq.
mile—and the highest average figure—28,26 tons/sq. mile—was
Bashley Road. The lowest monthly figure—9.13 tons/sq. mile—
and the lowest average figure—19.47 tons/sq. mile—was that at
Kendal Avenue,
