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

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

 did not (h udder as. in cold paroxyfm of fever ; his tongue from 

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

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

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

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

 muflc and fait of hartftiorn, and recovered in an hour or two 

 without any cold fweat. 



There being no cold fweat feems to indicate, that there was 

 no accumulation of ferous fluid in the lungs j and that their 

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

 fympathy of the air-cells with fome diftant part. There was 

 no muddering produced, becaufe the lungs are not fenfible to 

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

 room into a frofty air, and the contrary. So the fteam of hot 

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

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

 fit might be owing to fuppuration in fome part of the cheft ; as 

 the general difficulty of breathing feemed to be increafed after a 

 few days with pulfe of 1 20, and other figns of empyema. Do 

 the cold fweat, and the occurrence of the fits of afthma after 

 fleep, diftinguifh the humoral afthma from the cold paroxyfm of 

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

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

 fpit up much matter at the time he died. 



3. Diabetes a timore. The motions of the abforbent veflels of 

 the neck of the bladder become inverted by their confent with 

 thofe of the fkin ; which are become torpid by their reverfe 

 fympathy with the painful ideas of fear, as in Sect. XVI. 8. I. 

 whence there is a great difcharge of pale urine, as in hyfteric 

 difeafes. 



The fame happens from anxiety, where the painful fufpenfe 

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

 men about to be examined for a degree at the univerfities the 

 frequency of making water is very obfervable. When this anxi- 

 ety is attended with a fleeplefs night, the quantity of pale urine is 

 amazingly great in fome people, and the micturition very fre- 

 quent.

4. Diarrhoea a timore. The abforbent veflels of the inteftines 

 invert their motions by direct confent with the (kin ; hence 

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

 company continued fear, along with coldnefs of the (kin. The 

 immediate cauie of this is the decreafed fenforial power of afib- 



ciation,
