example, he directly warns his audience that to accept 

 the conclusions which he conceives himself to have 

 established on Protoplasm, is to accept these also : 

 That " all vital action" is but " the result of the molec- 

 ular forces" of the physical basis ; and that, by conse- 

 quence, to use his own words to his audience, " the 

 thoughts to which I am now giving utterance, and your 

 thoughts regarding them, are but the expression of 

 molecular changes in that matter of life which is the 

 source of our other vital phenomena." And, so far, 

 I think, we shall not disagree with Mr. Huxley when 

 he says that " most undoubtedly the terms of his propo- 

 sitions are distinctly materialistic." Still, on the second 

 issue, Mr. Huxley asserts that he is " individually no 

 materialist." " On the contrary, he believes material- 

 ism to involve grave philosophical error ;" and the 

 " union of materialistic terminology with the repudia- 

 tion of materialistic philosophy" he conceives himself 

 to share " with some of the most thoughtful men with 

 whom he is acquainted." In short, to unite both issues, 

 we have it in Mr. Huxley's own words, that it is the 

 single object of his essay " to explain how such a union 

 is not only consistent with, but necessitated by, sound 

 logic ;" and that, accordingly, Jie will, in the first place, 

 " lead us through the territory of vital phenomena to 

 the materialistic slough," while pointing out, in the sec- 

 ond, "the sole path by which, in his judgment, extrica- 

 tion is possible." Mr. Huxley's essay, then, falls evi- 

 dently into two parts ; and of these two parts we may 

 say, further, that while the one that in which he leads 

 us into materialism will be predominatingly physiolog- 

 ical, the other or that in which he leads us out 

 of materialism will be predominatingly philosophical.
