but their stronger vitality enabled them to resist longer. It was 
also remarked that the extremities of the leaves of some wheat 
plants, growing in the same vessel, became yellow. But those 
wheat plants which had germinated in the ozone atmosphere, al- 
though much smaller, were perfectly healthy, and the leaves 
showed no disposition to die at the ends. 
Pasteur has lately shown that the putrefaction and oxydation 
of organic bodies is effected to a very large extent by the inter- 
vention of the lowest order of vegetable organisms. That in

action of saline solutions, and to that of river water nearly pure, 
in both cases with and without the influence of ozone. Clearly, 
therefore, to nothing but ozone could be ascribed the inverted 
tendency of the roots, as this always followed its presence, an
