Part II.— The Botanical Results. 
Introduction; Scope of the Experiments , and Mode of Experimenting. 
In Part I. (Phil. Trans., Part I., 1880), under the title of “ The Agricultural Results ,” 
a general description of the experiments, with full particulars of the conditions 
of manuring of each of the more than 20 plots, was given. The effects of each 
condition of manuring on the character of growth of the herbage, as illustrated in the 
quantities of produce yielded, and in the amounts of nitrogen and of mineral matter 
taken up, on each plot, were also fully considered. But, so varied were the components 
of the mixed herbage, both as to the species grown, and as to the character of develop-
