from bile may be found different from that which has been 

 given in our analytical developement of this subject. 

 But this, if it should happen, can have but little effect on 

 our formulae ; if the relative proportions of carbon and 

 nitrogen be not changed, the differences will be confined 

 to the proportions of oxygen and hydrogen. In that case 

 it will be necessary for the developement of our views in 

 formulae, only to assume that more water and oxygen, or 

 less water and oxygen, have taken a share in the meta- 

 morphosis of the tissues ; but the truth of the develope- 

 ment of the process itself will not be by this means 

 affected.
