The article in Tellus: A Bimonthly Journal of Geophysics appeared in
vol. 26 no.
1 (1974) 2-10. Manuscript received May 8, revised version August 20, 1973. On
page 2: "The notion of the biophere as an active adaptive control system able
to maintain the Earth in homeostasis we are calling the 'Gaia' hypothesis,
Lovelock (1972)"--same reference as above.
