(&) The Decomposition of Carbon Dioxide.—The influence oflight upon the evolution of oxygen is greater the more carbonic acidis contained in the air; only those rays which are visible have thepower of decomposing caibonic dioxide, and those which appear bright-est to the eye (the yellow rays) are alone as efficacious in this processas all the others put together. (c) The Formation of Starch in Chlorophyll Granules.—Theformation of starch is a function of chlorophyll granules exposed tolight, its absorption a function of chlorophyll granules not exposed tolight. The formation of starch in chlorophyll granules depends onconditions which favor assimilation; and the principal feature of the. Plate 221.—The Upright Electric-Light Bath. The general indications for this appara-tus are the same as for the horizontal cabinet, and the application is the same, but personssnfFering from cardiac lesions, and especially obese patients, are often more favorably treatedin vertical positions.
