The temperature slowly subsided, with a steady improvement in
the physical signs, and at the end of about ten weeks he left
for home with only slight dulness and incapacity for active
exertion remaining. (Now again on active service.)

[Illustration: TEMPERATURE CHART 5.--Haemothorax, primary and secondary
rises of temperature, on each occasion falling on the evacuation of the
blood. Case No. 156]

(156) _Severe haemothorax. Recurrent secondary effusion. Tapping
on two occasions. Cure._--The patient was wounded at
Paardeberg, and arrived at the Base on the eighteenth day.
_Entry_, below the first rib, just external to its junction
with the costal cartilage; _exit_, through the ninth rib, just
within the posterior axillary line. The whole right side of the
chest was dull, with signs of the presence of fluid, the heart
being displaced to the left. There was considerable distress;
the respirations averaged 40, the pulse 100, and the
temperature reached 101.5 deg. the first evening after arrival.

On the nineteenth day the thorax was aspirated (Mr. Hanwell)
and 50 ounces of dirty red-coloured fluid, half clot, half
serum, were evacuated. Considerable relief was afforded; the
respirations became slightly less frequent; the heart returned
to a normal position, and distant tubular respiration was
audible. The temperature dropped to normal the third day after
evacuation of the fluid, but on the sixth day it again
commenced to rise, and meanwhile fluid again began to collect.

On the twenty-sixth day a second aspiration resulted in the
evacuation of 35 ounces of bloody fluid in which flakes of
lymph were found. Three days later the temperature became
normal. The respirations fell to 22, and the patient made an
uninterrupted recovery.

development of Haemothorax, with rise of temperature. Spontaneous
recovery. Case No 157]

(157) _Moderate haemothorax. Secondary effusion at the end of
twenty days. Spontaneous recovery._--Wounded at Paardeberg;
range from 700 to 1,000 yards. _Entry_, in the centre of the
second right intercostal space, anteriorly; _exit_, at the
level of the sixth rib posteriorly, through the scapula, close
to its vertebral margin.

The patient arrived at the Base
