molecular life. Molecular life is the sum of atomic 

 life this life is eternal. 1 



But it does not want the microscope to teach us this 

 great fact. Let us consider the hair on our heads. It 

 is probably on an average three inches long. We go to 

 a hairdresser about once a month, and have an average 

 of about an inch cut off. The hair cut off is so much 

 dead matter so called. Obviously in three months' 

 time the hairdresser will have cut off the whole of the 

 present crop of hair. The whole of the crop becomes, 



which ifc finally succumbs, leaving the organism to be resolved by 

 their agency into the components from which its materials were 

 originally drawn. The history of a Living Organism, then, is one of 

 incessant change; and the conditions of his change are to be found 

 partly in the organism itself, and partly in the external agencies 

 to which it is subjected." (" Carpenter's Principles of Human 

 Physiology," 9th edition, 1881, p. 2.) 



' The living body yields energy in the form of work and of he'it. 

 This result is brought about by chemical action. Matter is used up 

 and becomes useless, organic compounds disintegrate and their 

 waste products are got rid of. Consumption of matter is thus a 

 primary condition of vital activity, and it is necessary to the con- 

 tinuance of life that new matter should take the place of spent 

 matter. The food proteids, fats, and carbohydrates supplies the 

 necessary new matter, and is the primary source of all body energy, 

 by its transformation into work, heat and waste products. The 

 essential waste products are urea and carbon dioxide; the essential 

 elements in these waste products as well as in the food are nitrogen 

 and carbon" ("An Introduction to Human Physiology," A. D. 

 Waller, M.D., F.R.S., 1896, p. 248.) 



1 "Every variation of a living form, however minute, however 

 apparently accidental, is inconceivable except as the expression of 

 the operation of molecular forces or ' powers ' resident within the 

 organism. And. as these forces certainly operate according to definite 

 laws, their general result is, doubtless, in accordance with some 

 general law which subsumes them all." (" Critiques and Addresses," 

 T. H. Huxley, LL.D., F.B.S., 1890, p. 298.)
