DYNAMICAL VIEW OF ORGANIC CHEMISTRY. 159 



the correlative change in composition undergone by these pro- 

 ducts into water and carbonic acid is attended by a liberation of 

 the force stored up in them ; that in every organ of the animal 

 body oxidation is continually taking place to furnish that organ 

 with the force necessary for the performance both of its nutritive 

 acts and external manifestations ; that the juice of every gland 

 and muscle is crowded with oxidised products of its own meta- 

 morphosis, similar to, or even identical with, those procurable 

 by an artificial oxidation of the selfsame tissue out of the body ; 

 that inasmuch as the exercise of every function of the living body 

 is attended by, and consequent upon, a change of chemical com- 

 position, the investigation of every action of the body, even of 

 those which are the most mechanical, becomes to a large extent a 

 chemical question ; and lastly, that while perversions of nutrition, 

 perversions of metamorphosis, and the modifying influence of re- 

 medies, are many-sided subjects which may be viewed from many 

 different aspects, he must have but a very imperfect and one-sided 

 view of these subjects, who leaves the chemical aspect altogether 

 out of his consideration.
