injuries.
This case was an interesting one of recurrent haemorrhage followed by
inflammatory troubles:--

Haemothorax. Case No. 151]

(151) The wound was received at short range, probably at from
100 to 200 yards. _Entry_, 1 inch from the left axillary margin
in the first intercostal space; _exit_, at the back of the
right arm 1-1/2 inch below the acromial angle; both pleurae were
therefore crossed. The patient expectorated at first fluid,
then clotted, blood in considerable quantity. When brought into
the advanced Base hospital on the third day, there were signs
of blood in the left pleura, cellular emphysema over the right
side of the chest, and signs of collapse of the right lung. The
temperature chart gives shortly the course of the case: the
right pneumo-thorax cleared up spontaneously, also the
emphysema; but the left pleura needed tapping to relieve
symptoms of pressure on four occasions, the 13th, 15th, 19th,
and 25th days respectively. On the first two occasions blood
was removed, on the third blood serum only, and on the last
pus. The patient was relieved after each aspiration; after the
third, the temperature fell to normal, the general condition
also improved, and he promised to do well. None the less,
reaccumulation took place, the evacuated fluid assumed an
inflammatory character, and an incision to evacuate pus was
eventually followed by death on the twenty-seventh day. The
amount of haemoptysis throughout was considerable, and the case
was possibly one of pulmonary haemothorax, as after death no
source of haemorrhage could be localised in the intercostal
space. The track in the lung was almost healed, and although a
part of it allowed the introduction of a probe for about an
inch, it could be traced no further even on section of the
organ, and no special vessel could be located as the original
bleeding spot.

_Empyema._--I may here add the little that I have to say on this
subject. During the whole campaign the single case of primary empyema
that I saw was the one recorded below, which deserves special mention as
illustrating the disadvantage of extracting bullets on the field. Under
the conditions which necessarily accompanied this operation the
ensurance of asepsis was impossible, an
