of transferred eases in this population, assuming the incidence rate
to equal that occurring in the Metropolitan population, would be
62 pulmonary and 25 non-pulmonary cases. Actually the number
of transfers is much less than this.
Of the primary pulmonary notifications, 74 per cent, were
original cases, and 26 per cent were transfers. Of the percentage
of original cases, 64 were of persons resident in the Estate houses, J
occupied houses erected since ] 921 and 6 were occupants of the
older houses. Of the percentage of transfers, 23 were occupants
of Estate houses. Of those in whom the disease was first diagnosed
while the persons were residing here, in not all cases could it be
assumed that the onset had occurred within that period. Six
cases were notified as suffering from pulmonary tuberculosis
within six months of transferring here and a total of 12 within 1?
months. These persons, in most cases, gave their history of onset
of illness oidy shortly before being notified, but considering the
usual delay in seeking medical advice, it is very probable that most,
if not all, of these patient s had contracted their illness before coming
to reside in this area.
Of the non-pulmonary eases notified, 16 per cent, were transfers,
all of these being residents of Estate houses. Of the other
cases, in 4 the onset was within six months of their residing here,
the disease probably having been contracted before removal of the
patient from his previous residence. 5 per cent, of the nonpulmonary
cases occurred amongst occupants of the older property
of the district.
Of the persons suffering from pulmonary tuberculosis who
were first notified in this area, the onset of illness occurred within
six months of residence here in 6 cases, in the second six months
7 cases ; in the second year 9 cases; in the third 18 ; in the fourth,
fifth and sixth years 13, 7 and 6 respectively ; and 10 cases occurred
amongst persons who had lived here six years and over. Of the
non-pulmonary cases, the onset of 4 was within six months of
residence and 6 within twelve months. In 5 cases the onset was
in the second year and 10, 3, 1 and 4 in the third to sixth years,
and one in a person who had lived here over 6 years.
Of the non-pulmonary cases who were first notified here, 10
were persons of over school age. Of these, glands were affected in
4 instances, the spine in 2, the intestines in 2, the tongue in one and
one person died of meningitis. Seven children of school age were
notified as suffering from tuberculous glands and 4 children of under
school age. Meningitis was notified 3 times in children of 5 and
under; tuberculosis of the spine in 4 and of the hip in 1- Three
children of school age suffered from a tubercular spine, and 2 from
tubercular peritonitis. Of children of under school age, a family
