vegetable organisms are but properties of the molecular 

 affections of their chemical constituents, only if the func- 

 tions of the protoplasm, of which they are composed, 

 are but properties of the molecular affections of its 

 chemical constituents. In disproof of the affirmative 

 in both clauses, there has been no object but to demon- 

 strate, on the one hand, the infinite non-identity of pro- 

 toplasm, and, on the other, the dependence of its func- 

 tions upon other factors than its molecular constituents. 

 In short, the whole position of Mr. Huxley, that all 

 organisms consist alike of the same life-matter, which 

 life-matter is, for its part, due only to chemistry, must 

 be pronounced untenable nor less untenable the mate- 

 rialism he would found on it.
