To trace out completely all the sub- 

 jects which this table exhibits, would 

 lead into a very wide field of discussion ; 

 we shall, after devoting a short space to 

 the consideration of those vital powers 

 which animate living bodies, shortly con- 

 sider the principal functions. 



Of the Vital Powers, Sensibility and 

 Contractility. 



Struck with the numerous differences 

 that are observable between 'organized 

 and living, and inorganic matters, philo- 

 sophers have admitted in the former a 

 peculiar principle of action, a force which 

 maintains the harmony of their functions, 

 and directs them all to one object ; the 

 preservation of the individual and of the 

 species. No one at present doubts the 

 existence of a living principle, which sub- 

 jects the beings endued with it to a differ- 

 ent order of laws from those which go- 

 vern inanimate things, and whose princi- 



pal effects are seen, in its removing the 

 bodies which it animates from the agen- 

 cy of chemical affinities, to which the 

 multiplicity of their elements would 

 otherwise have rendered them prone ; 

 and in its maintaining their temperature 

 at an uniform standard. All the pheno- 

 mena observed in the living animal body 

 might be cited in proof of this principle, 

 The effects produced on the food by the 

 digestive organs ; its absorption by the 

 lacteals; the circulation of the nutritive 

 juices in the blood-vessels ; the changes 

 which they undergo in the lungs and se- 

 cretory glands ; the capability of receiv- 

 ing impressions from external objects, 

 and the power of approaching to, or 

 avoiding them, all demonstrate its exist- 

 ence. But we prove it more directly by 

 means of the two properties, with which 

 the organs of these functions are endued. 

 These are, sensibility, or the faculty of 

 feeling ; the aptness to receive, from the 

 contact of foreign bodies, more orlesa vi-
