The principal argument in favour of such a dissociation of the iodine molecule has been obtained from the study of the nature of fluorescence of iodine vapour. [...] Since energy and mass is connected by the relation c' (2) where c is the velocity of light we obtain for the sum of the masses of the protcn and the electron produced in the above process M '1)1 = [ 2hv-3kT 1. 1 c2 The mass of an electron 2 e2.3 —a (4) where a is the radius of the electron and e=1 59 10-r E. M. U. Prof. [...] If the velocities of formation of formaldehyde and its conversion into hexoses are of the same order of magnitude then it is clear that the concentration of formaldehyde at any time in the juices of the plant leaves may be exceedingly minute. [...] of the gas can diffuse into the leaf in an hour the energy supplied is now just sufficient to allow the assimilation of the CO. If the concentration of CO is raised still further increase in the rate of assimilation cannot take place because the energy supplied is only capable of decomposing 5 c.c. [...] (1) The rate of transformation of the chlorophyll carbonic acid addtive complex into the peroxide under the influence of light is propotional to the intensity of illumination and to the number of additive complex molecules present per unit area and hence Nat...
