unpleasantly chilly till breakfast had been taken, and then a 
slight degree of pyrexia was perceived ; the heat of surface 
being increased, the pulse quickened, and the mouth slightly 
parched. After breakfast, the thermometer was applied to 
both hypochondriac regions, and the left was found one degree 
higher than the right. 
To ascertain the temperature of different parts of the sur- 
face beneath the integuments, the bulb of a thermometer was 
introduced through small incisions about half an inch between 
the skin and subjacent parts of a lamb just dead. The heat of 
the rectum was first ascertained, as a means of marking the 
rate of cooling, and the different parts were then tried in the 
following order. 
Venous blood in the jugular vein - 105.5 
Arterial blood from the carotid artery - 107 
Rectum - - - 105.5 
Over the metatarsal bone - “97 
Over the tarsal bone - - 90 
Over the knee joint - - - loa 
About the head of the thigh - - 103 
At the groin - - - - 104. 
Nearly a quarter of an hour had been occupied in making 
these observations, and the temperature of the rectum was 
now found to be 105. The three great cavities were next 
opened in the order enumerated. 
Near the lower part of the liver - - 106 
The substance of the liver - - 10^.5 
The substance of the lung - _ - 106.5
