elation, which intervenes between the actions of the abforbents 

 of the cold fkin, and thofe of the inteftinal abforbents ; the mo- 

 tions of the latter become on that account weakened and at 

 length retrograde. The remote caufe is the torpor of the vef- 

 fels of the fkin catenated with the pain of fear, as explained in 



Sea. XVI. 8. i. 



The capillaries of the Ikin confent more generally by direct 

 fympathy with thofe of the lower interlines, and of the bladder j 

 but by reverfe fympathy more generally with thofe of the ftom- 

 ach and upper interlines. As appears in fevers, where the hot 

 fkin accompanies indigeftion of the ftomach ; and in diarrhoeas 

 attended with cold extremities. 



The remote caufe is the torpor of the Ikin owing to its reverfe 

 fvmpathy with the painful fenfual motions, or ideas, of fear ♦, 

 which are now actuated with great energy, fo as to deprive the 

 fecond link of affociated motions of their due (hare of fenforial 

 power. It is alfo probable, that the pain of fear itfelf may con- 

 tribute to exhaufl the fenforial power, even when it produces net 

 mufcular action. See Clafs IV. 2. 2. 



5. Pallor et tremor a iimore. A retrograde action of the ca- 

 pillaries of the fkin producing palene'is, and a torpor of the muf- 

 cular fibres of the limbs occafiomrg trembling, are caufed by 

 their reverfe aflbciations with the ideas cr imaginations of fear ; 

 which are now actuated with violent energy, and accompanied 

 with great pain. The caufe of thefe arTociations are explained 

 in Sea. XVI. 8. 1. 



Thefe torpid aaions of the capillaries and mufcles of the 

 limbs are not caufed immediately by the painful fenfation of 

 fear ; as in that cafe they would have been increased and not 

 decreafed aaions, as occurs in anger ; where the painful voli- 

 tion increaies the aaions of the capillaries, exciting a blufh and 

 heat of the fkin. Whence we may gain fome knowledge of 

 what is meant by deprefling and exciting pafhons; the former 

 confiding of ideas attended with pain, which pain occafions no 

 mufcular aaions, like the pain of cold head-ach *, the latter be- 

 ing attended with volitions, and confequent mufcular exertions. 



That is, the pain of fear, and the pain of anger, are produced 

 by the exertion of certain ideas, or motions of certain nerves of 

 fenfe •, in the former cafe the painful fenfation of fear produces 

 no riiufcular aaions, yet it exhaufls or employs fo much fenforial 

 power, that the whole fyftem aas mere feebly, or becomes 

 retrograde ; but fome parts of it more fo than others, according 

 to their early aflbciations defcribed in Sea. XVI. 8. 1. hence 

 the tremor of the limbs, palpitation of heart, and even fyncope. 

 In anger the painful volition produces violent mufcular aaions ;
