AN illustrated article dealing with this question of the heterogenetic origin from small Zooglœa masses of Fungus-germs, Monads, or Amœbæ, written by me, appeared in NATURE of November 24, 1904. That article was prepared at short notice in consequence of a short letter on “Archebiosis and Heterogenesis,” which appeared a fortnight previously, and at a time when I was not specially working at this subject. Of late I have been doing much work in this direction, and have made out many very important new points, and can now speak with more precision concerning the changes generally, and the modes of obtaining them.
Where the infusion has been made at a higher temperature, such as 100°102° F., the appearance of the brown Fungus-germs may he still further delayed. What I have to say in this communication refers only to the products from the Zooglas that may be found within the first fourteen days.
