NOTE. 



*** Since the first edition of this work was published, Mr. Huxley's 

 essay on the " Physical Basis of Life," has been submitted to a very just 

 but clear and searching philosophical criticism by Mr. James Hutchison 

 Stirling, of Edinburgh, whose excellent treatise I very strongly recom- 

 mend my readers carefully to study. I should have taken from it many 

 extracts, but the work is easily obtained, and readers should see it in a 

 complete form. Mr. Stirling concludes in the following words, "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 to 

 chemistry, must be pronounced untenable nor less untenable the 

 materialism he would found on it."
