BACTERIOLOGICAL EXAMINATION OF MILK.
During the year 1931, six samples of milk were taken in various parts of the
Borough, as supplied to the consumer. In addition to the bacterial count to see
whether the specimen complied with the Grade, if any, under which it was sold, the
specimens were examined for tubercule bacilli by animal inoculation. All the
samples fulfilled the standard bacteriological requirements. Two samples, however,
seemed only to have been made suitable by pasteurisation. No evidence of
tubercle bacilli was found in any of these specimens.
VACCINATION.
During the year Dr. Hynes resigned his position as Public Vaccinator for
Tufnell, and Dr. D. W. Latham, 18, Mercers Road, N.19, was appointed.
Dr. H. E. Whitehead, the Public Vaccinator for very many years for East
Lower Holloway, and a much esteemed practitioner in the borough, died on the
1st September, 1930. Dr. F. E. Clay, who succeeded him in his practice, was
appointed his successor as Public Vaccinator.
No vaccinations were performed by the Medical Officer of Health under the
Public Health (Smallpox Prevention) Regulations, 1917, as it was possible to refer
each case immediately to the Public Vaccinator of the district or institution.
Vaccinations.—Of the 4,465 births registered in 1930, the returns of vaccination
shows that only 2,181 infants were successfully vaccinated, while 18 were
found to be insusceptible. There were also 205 who died unvaccinated, and 1,584
statutory declarations of conscientious objection to vaccination were obtained by
the parents or guardians; 39 vaccinations were postponed under medical authority;
372 were removed to other districts or places unknown, thus leaving 66 unaccounted
for. The return of certificates of exemption, therefore, represents 35 per cent, of
the registered births.
Vaccination per 100
Years. births, less infants who
