152 CAPILLARY SYSTEMS, 



Q. Mention some'of the effects of sympathy on animal 

 heat. 



#. In syncope it is greatly reduced; in phthisis the 

 hands and feet burn; in fever the heat is locally or gene- 

 rally increased. Now, in all these cases, the vital forces 

 of the parts are sympathetically changed. 



Q. How do you account for the sensations of heat in 

 a part which are so delusive, that the parts to a bystander 

 feel cold? 



fl. This is a sympathy of animal sensibility; whereas 

 actual increase of heat is a sympathy of organic sensi- 

 bility. 



Q. Why in the natural state of the body is only a cer- 

 tain temperature developed ? 



/?. It is not known ; nor is it known why the pulse beats 

 a given number of times in a minute, nor why a certain 

 number of respirations are made in the same time. It 

 may be said that this is the primitive order of the vital 

 actions. 



II. PULMONARY CAPILLARY SYSTEM. 



Q. What do you mean by this pulmonary capillary 

 system ? 



A. Exclusively the system of vessels between the pul- 

 monary artery and the pulmonary veins. 



Q. In regarding this system, what distinction is to be 

 drawn? 



#. That it be not confounded with the capillaries be- 

 tween the bronchial arteries and veins; they are attached 

 to the general capillary system.
