the eldest. The President concluded his address to him by saying : 

 " The Rothamsted results will be for ever memorable ; they are unique, 

 and characteristic of the indomitable perseverance and energy of our 

 venerated President, Sir Henry Gilbert." 



Of the Linnean and Meteorological Societies Sir Henry Gilbert was 

 also a Fellow, and occasionally read papeis at their meetings. He was 

 also a member of the Society of Arts. He became a member of the 

 Scientific Committee of the Horticultural Society in 1868, and for 

 many years regularly attended its meetings. 



In his summer holidays the meeting of the British Association for 

 the Advancement of Science was generally attended ; his attendance 

 commenced in 1842, and during many years he scarcely missed a 

 meeting, and frequently lead a paper describing some of the Rothamsted 

 results. In 1880 he was President of the Chemical Section, and gave 

 as his address : "A Sketch of the Progress of Agricultural Chemistry." 

 A tour on the Continent generally formed part of the summer holiday ; 

 agricultural laboratories and experimental stations were then visited, 

 and the Naturforscher Yersammlung, and other scientific gatherings, 

 were often attended and papers read before them. In 1871, and the 

 following year, the details of sugar beet culture were studied in Germany, 

 Austria, and France, preparatory to the commencement of experiments 

 on this subject at Rothamsted. 



Three visits were paid to the United States and Canada. In 1882 

 he attended the meeting of the American Association for the Advance- 

 ment of Science, at Montreal, and brought before them the recent 

 determinations of nitrogen in the experimental soils at Rothamsted. 

 A tour of nearly three months was afterwards made in the United 

 States. In 1884 he was again at Montreal, at the meeting of the 

 British Association, and afterwards made a second extensive tour 

 through North America. The last visit was paid in 1893, after the 

 celebration of the Rothamsted jubilee, for the purpose of delivering a 

 course of lectures on the Rothamsted experiments, in accordance with 

 a provision of Sir John Lawes' trust deed. Sir Henry Gilbert first 

 attended the Agricultural Congress held in connection with the World's 

 Fair at Chicago ; here he had a splendid reception, all present rising and 

 cheering for some time. To this Exhibition at Chicago a large collec- 

 tion of diagrams had been sent from Rothamsted, and for these a 

 medal was afterwards awarded. Sir Henry Gilbert then gave a course 

 of seven lectures at the State Agricultural College at Amherst, Mass., 

 taking as his subject the chief results relating to the crops ordinarily 

 grown in rotation, with those relating to the feeding of animals, 

 obtained at Rothamsted j during the previous fifty years. These 

 lectures, in an enlarged form, were afterwards published by the United 

 States Department of Agriculture, and were reprinted, with an intro-
