so8 Mr. Brqdie’s Observations and Experiments 
a temperature of 85 of Fahrenheit’s thermometer, ancl the 
lungs were artificially inflated about forty times in a minute. 
The heart continued acting regularly. 
When the artificial respiration had been kept up for forty 
minutes, the pupils of the eyes were observed to contract and 
dilate on the increase or diminution of light ; saliva had flowed 
from the mouth, and a small quantity of tears was collected 
between the eye and eye-lids ; but the animal continued per- 
fectly motionless and insensible. 
At the end of an hour and fortv minutes, from the same 
period, there were slight involuntary contractions of the 
muscles, and every now and then there was an effort to 
breathe. The involuntary motions continued, and the efforts 
to breathe became more frequent. At the end of another hour, 
the animal, for the first time, gave some signs of sensibility 
when roused, and made spontaneous efforts to breathe twenty- 
two times in a minute. The artificial respiration was discon- 
tinued. She lay, as if in a state of profound sleep, for forty 
minutes, when she suddenly awoke, and walked away. On 
the following day she appeared slightly indisposed ; but she 
gradually recovered, and is at this time still alive and in 
health. 
Experiment 2. Some woorara was applied to a wound in a 
rabbit. The animal was apparently dead in four minutes after 
the application of the poison ; but the heart continued acting. 
He was placed in a temperature of 90°, and the lungs were arti- 
ficially inflated. The heart continued to act about one hundred 
and fifty times in a minute. For more than three hours the 
pulse was strong and regular ; after this, it became feeble and 
irregular, and at the end of another hour the circulation had
