It was suggested in a previous paper [Common, Rutledge & Bolton, 1947] that the increase in the fowl's serum riboflavin evoked by oestrogen cannot easily be explained as an outcome of mobilization and withdrawal of riboflavin from liver reserves. The relevant observations have been repeated and extended to include observations on the total dry matter, protein and fat contents of the livers of the experimental birds. The influence of thyroxine treatments on the effects of gonadal hormones was also investigated. The results of these two experiments form the subject of the present paper. The general technique has been described in our previous paper. The experimental birds were sexually immature White Wyandotte pullets of the same strain as those in all the previous experiments, except Exp. 6 [Common, Rutledge & Hale, 1948]. All the pullets in any experiment were given the same amount of food daily. In all cases the gonadal
