disease is rare.

#The clinical features# of surgical tuberculosis will be described with
the individual tissues and organs, as they vary widely according to the
situation of the lesion.

#The general treatment# consists in combating the adverse influences
that have been mentioned as increasing the liability to tuberculous
infection. Within recent years the value of the "open-air" treatment has
been widely recognised. An open-air life, even in the centre of a city,
may be followed by marked improvement, especially in the hospital class
of patient, whose home surroundings tend to favour the progress of the
disease. The purer air of places away from centres of population is
still better; and, according to the idiosyncrasies of the individual
patient, mountain air or that of the sea coast may be preferred. In view
of the possible discomforts and gastric disturbance which may attend a
sea-voyage, this should be recommended to patients suffering from
tuberculous lesions with more caution than has hitherto been exercised.
The diet must be a liberal one, and should include those articles which
are at the same time easily digested and nourishing, especially proteids
and fats; milk obtained from a reliable source and underdone
butcher-meat are among the best. When the ordinary nourishment taken is
insufficient, it may be supplemented by such articles as malt extract,
stout, and cod-liver oil. The last is specially beneficial in patients
who do not take enough fat in other forms. It is noteworthy that many
tuberculous patients show an aversion to fat.

For _the use of tuberculin in diagnosis_ and for _the vaccine treatment
of tuberculosis_ the reader is referred to text-books on medicine.

In addition to increasing the resisting power of the patient, it is
important to enable the fluids of the body, so altered, to come into
contact with the tuberculous focus. One of the obstacles to this is that
the focus is often surrounded by tissues or fluids which have been
almost entirely deprived of bactericidal substances. In the case of
caseated glands in the neck, for example, it is obvious that the removal
of this inert material is necessary before the tissues can be irrigated
with fluids of high bactericidal value. Again, in tuberculous ascites
the abdominal cavity is filled with a fluid practically devoid of
anti-bacterial substances, so that the bacilli are able to thrive and
work their will on the tissues. When the stagnant fluid
