such alterations as might seem desirable, for wider 

 circulation, especially among those connected with 

 Agricultural Investigation, or Agricultural Education, 

 both in this country and abroad, to whom it is sup-

 Accordingly, some changes in form and arrangement 

 have been made, and the record has been brought up 

 to date, for the purposes of the present issue. With 

 the exception of such changes, the report is essentially 

 the same as that presented, in 1889, to "The Lawes

It should be further stated, that an Appendix has been 

 added (pp. 64-74), giving lists of Eothamsted papers 

 already published, arranged in two Series, and within 

 each Series numbered in chronological order. They also 

 show, both where each paper originally appeared, and 

 the date of its publication. These lists are similar to 

 those given in the " Memoranda " (see below), and they 

 are given here, not only for purposes of general refer- 

 ence, but especially to facilitate reference to the titles 

 of the papers, or to the papers themselves, which are 

 referred to in the Keport under the same numbers as 

 those in the lists.

 of the Field and other experiments conducted on the Farm 

 and in the Laboratory" at Rothamsted, gives a great 

 deal of information as to what are the various lines 

 of experiment carried on, and the lists of published

 upon. 



In this annual Memorandum, there is first given a 

 general description of the lines of enquiry in progress, 

 then follow lists of the papers published, with full 

 reference to where they appeared, and then are given 

 summaries, chieHy in the Tabular form, and for the
