12 THE ORIGIN OF LIFE 



in this direction received, therefore, little or no 

 recognition of a favourable kind, and as the work 

 in which they are embodied is expensive, I pro- 

 duced, in 1905, a smaller book, entitled The 

 Nature and Origin of Living Matter, in which, 

 among other subjects, an account was included of 

 some of the most remarkable heterogenetic changes 

 that I had observed. 



Towards the end of this same year I began again 

 to take up experimental work, in an endeavour to 

 find further proof of the continued occurrence of 

 a de novo origin of living matter the process 

 which Huxley termed Abiogenesis, but which I 

 had previously named Archebiosis. 



This time my attempts to procure evidence of 

 the occurrence of the process were made, not with 

 infusions or solutions of organic matter, such as 

 had been almost solely employed in previous years 

 by others as well as by myself, but with mere 

 saline solutions such as would alone have existed 

 on the surface of the Earth when life-evolving 

 processes were first initiated. 



Some striking results were obtained in these ex- 

 periments in 1906 with solutions that in each case 

 contained small quantities of colloidal silica and a
