15. "I think Professor Huxley is the first 

 observer who has spoken of the cell in its 

 entirety as a mass of protoplasm, and the only 

 one who has ever asserted that any tissue in 

 nature is composed throughout of matter which 

 can properly be regarded as one in kind. This 

 view is quite irreconcilable with many facts, 

 some of which have been alluded to by Mr. 

 Huxley himself. I doubt if in the whole range 

 of modern science it would be possible to find 

 an assertion more at variance with facts familiar 

 to physiologists than the statement that ' beast 

 and fowl, reptile and fish, mollusc, worm, and 

 polype,' are composed of ' masses of protoplasm 

 with a nucleus,' unless it be that still more 

 extravagant assertion that what is ordinarily 

 termed a cell or elementary part is a mass of 

 protoplasm ; for can anything be more unlike the 

 semi-fluid, active, moving matter of amoeba pro- 

 toplasm, than the hard, dry, passive, external 

 part of a cuticular cell or of an elementary 

 part of bone ?" 8
