compose the various parts of animals, in such a manner that 

 one (being predominant) influences the nature of that part of 

 the animal which it is principally employed to form ; and as 

 albumen, gelatin, and fibre, by relative proportion, by the de- 

 grees of density, by the effects of organization which singly or 

 conjointly they have experienced, by the texture of the animal 

 substance which they, as materials and thus modified, have 

 concurred to produce, and by the proportion of natural or 

 inherent moisture peculiar to each part of different animals, 

 present an immense series of complicated causes, so are the 

 effects found to be no less numerous and diversified, by the 

 infinite variety in texture, flexibility, elasticity, and the many 

 other properties peculiar to the various parts which compose the 

 bodies of animals. 



albumen and gelatin ; after which, a substance remains, in appearance very analogous 

 to muscular fibre, excepting that it is in a more attenuated state. This substance 

 (called fibrin by chemists) may be regarded as that part of the blood which has 

 undergone the most complete animalization ; and from which the muscular fibre and 

 other organs of the body are formed.
