24 THE LAWS OF ORGANIC 



always been extremely timid : it was white and 

 full grown. From exhibiting great trepidation 

 on even a distant approach, I proposed to select 

 this for the purpose of ascertaining the influence 

 of the mind on the production of heat. I made 

 an attempt to catch it, but was unsuccessful, as 

 it almost immediately escaped into a situation 

 inconvenient to enter ; but, while here, I observ- 

 ed well the great agitation of the body, such as 

 I had not seen before, nor have I since. This 

 animal, almost directly, lost its fine healthy ap- 

 pearance and appetite ; it partook of nothing 

 after this accident, and died in two days. On 

 dissection, the lungs were found to exhibit well 

 marked symptoms of inflammation, the liver was 

 much enlarged and congested, and the intestines 

 were, in certain parts, highly vascular. The 

 stomach was full of meat, which it had taken be- 

 fore this occurrence, but which was scarcely, if 

 at all, acted upon by the gastric juice. From the 

 singularity of this case, I presented it to the 

 Edinburgh Hunterian Medical Society. Among 

 the crowded attendance of the evening was Mr 

 LiZARS,the distinguished anatomist and surgeon. 

 He and the other members examined the diseas- 

 ed parts with care, and agreed with the above 

 observations. This case, although an extreme 

 one, illustrates in a very striking manner the 

 opinion I have endeavoured to support regard- 

 Ing the changes in the distribution of the blood.
