1. Tuberculous lesions were found in 69 per cent.
of persons (386) who died in the Royal
Infirmary, Edinburgh, from disease other than
2. In 50 per cent. of cases calcareous, that is
healed lesions were found.
3. In 9 per cent. the lesions were quiescent and
in another 9 per cent. they were active.
4. Lungs and tracheo-bronchial glands are the
organs most frequently involved in adults.
5 . Lungs, tracheo-bronchial glands and mesenterie glands in that order, are the most
common sites of tubercle.
6. Other organs, except cervical glands, are
always infected secondarily to those
7. Tuberculosis of the kidney is always secondary and does not heal.
8. There is evidence of a marked tuberculisation
occurring during infancy of abdominal type
and of a late and more constant tuberculisation affecting lungs and bronchial glands in
9. Evidence is afforded by the figures relating
to abdominal glandular lesions of a marked
tendency for these lesions to disappear within`
the individual. The degree of tuberculisation of the population must therefore very
considerably exceed the percentage of the
tuberculous lesions which have been proved
in this series of examinations. It must
be greater than 69 per cent.
10. The facts which have been obtained from the
study of this particular population indicate
that in order that correct conclusions may
be obtainable from post-mortem material,
the factors of age incidence with respect
to the various manifestations of the disease
must be taken into account.
11. From the facts demonstrated that tuberculosis in later life is mainly pulmonary in
type and subacute or chronic in nature and
that in a large proportion of cases the
pulmonary must have been preceded in the
individual by definite abdominal tuberculosis, it would appear that a resistance
to this disease is active during later life, . and that the disease in a large number of
instances must.h &ve been due to alighting
up of an early infection and not to an reinfection.
