half an hour, the palpitation of his heart and difficult respiration 

 were very alarming; his whole skin was cold and pale, yet he 

 did not shudder as in cold paroxysm of fever; his tongue from 

 the point to the middle became as cold as his other extremities, 

 with cold breath. He seemed to be in the act of dying, except 

 that his pulse continued equal in time, though very quick. He 

 lost three ounces of blood, and took ten drops of laudanum, with 

 musk and salt of hartshorn, and recovered in an hour or two 

 without any cold sweat. 



There being no cold sweat seems to indicate that there was 

 no accumulation of serous fluid in the lungs; and that their 

 inactivity, and the coldness of the breath, was owing to the 

 sympathy of the air-cells with some distant part. There was 

 no shuddering produced, because the lungs are not sensible to 

 heat and cold; as any one may observe by going from a warm 

 room into a frosty air, and the contrary. So the steam of hot 

 tea, which scalds the mouth, does not affect the lungs with the 

 sensation of heat. I was induced to believe that the whole cold 

 lit might be owing to suppuration in some part of the chest; as 

 the general difficulty of breathing seemed to be increased after a 

 few days with pulse of 120, and other signs of empyema. Do 

 the cold sweat, and the occurrence of the fits of asthma after 

 sleep, distinguish the humoral asthma from the cold paroxysm of 

 intermittents, or that which attends suppuration, or which pre- 

 cedes inflammation? I heard a few weeks afterwards, that he 

 spit up much matter at the time he died. 



3. Diabetes a limore. The motions of the absorbent vessels of 

 the neck of the bladder become inverted by their consent with 

 those of the skin; which are become torpid by their reverse 

 sympathy with the painful ideas of fear, as in Section XVI. 8. 1 . 

 whence there is a great discharge of pale urine, as in hysteric 

 diseases. 



The same happens from anxiety, where the painful suspense 

 is continued, even when the degree of fear is small; as in young 

 men about to be examined for a degree at the universities, the 

 frequency of making water is very observable. When this anxiety 

 is attended with a sleepless night, the quantity of pale urine 

 is amazingly great in some people, and the micturition very fre- 

 quent.

4. Diarrhoea a timore. The absorbent vessels of the intestines 

 invert their motions, by direct consent with the skin; hence 

 many liquid stools as well as much pale urine are liable to ac- 

 company continued fear, along with coldness of the skin. The 

 immediate cause of this is the decreased sensorial power of asso-
