N this paper are presented the results of a preliminary exploration of the sequence of reactions involved in the sulphur metabolism of plants, and of the relations which exist between the amounts of the metabolites. In order to achieve this end we have employed the experimental method developed by Petrie & Wood (I938a); in its essentials this method entails alteration of the internal concentration of metabolites by applying to plants different treatments of one of them and then placing the treated plants in an environment constant in certain respects. Under these conditions it is possible that the systems in the plant will approximate to a drifting steady state. At this state it might be expected that the factors determining the amounts present of substances taking part in the metabolic reactions would be more clearly revealed. At intervals a certain number of plants corresponding to each treatment were removed and the amounts of various components of the system estimated by appropriate analytical methods. In this paper we are concerned only with the system present in the leaves and describe the effects of adding different dosages of potassium sulphate, ammonium chloride and cystine to the medium in which plants were growing.
