Hydrolysis of Starch Grains by Polarized Infra-Red Radiation
It was shown that polarized radiation had the effect of accelerating the change of starch grains, in a weak suspension of diastase and at ordinary laboratory temperature, into a crystalline reducing substance; but if the diast enzyme were active or concentrated, no selective effect was observed.

Photochemical Degradation of Starch
It was felt that this account of some of the observations made in what is practically a new field of research might be of interest to a wider circle. Expand
Bursting of Cell by Polarised Sunlight
AT a meeting of the Biochemical Society in November 1925, I read a paper on the “Hydrolysis of Starch in the Guard-Cells of the Leaf by Polarized Light”. This work has since been amplified andExpand
Hydrolysis in Green Plants by Moonlight
IN view of the recent interesting discussion on ‘Lunar Periodicity in Organisms’, which has appeared in these columns,1 some very simple experiments, carried out in South Africa in the grounds ofExpand
Hydrolysis of Starch Grains by Light Polarised by Small Particles
DURING the last three winters I have been engaged in an experiment, which throws additional light on the work described in a former paper (Baly and Semmens, Proc. Roy. Soc. B, 97, 250), and as theExpand
