122 THE POPULAR SCIENCE MONTHLY. 



Petrovskoie, and of the Royal Agricultural Society of Hanover ; 

 foreign member of the Royal Agricultural Academy of Sweden ; 

 and corresponding member of the Institute of France (Academy 

 of Sciences), of the Society of Agriculturists of France, of the So- 

 ciety for the Encouragement of National Industry, Paris, and of 

 the Institut Agronomique of Gorigovtsk. He is also Chevalier 

 du Me'rite Agricole, France, and, in conjunction with Sir J. B. 

 Lawes, gold-medalist of merit for agriculture, Germany. 



At the celebration of July 29th, separate testimonials, read by 

 the Duke of Westminster, were addressed to the colleagues by the 

 Prince of Wales. To Mr. Gilbert the prince said, offering his 

 congratulations on the completion of fifty years of the joint con- 

 tinuous labors of the two in the cause of agricultural science : 

 " The nature and importance of these labors are so well known 

 that it is needless to dilate upon them ; but if the institution of 

 the various investigations has been due to Sir John Lawes, their 

 ultimate success has been, in a great measure, secured by your 

 scientific skill and unremitting industry. Moreover, by your 

 lectures and writings you have been a leading exponent in this 

 and other countries of the theoretical and practical aspects of the 

 researches that have been undertaken at Rothamsted. A col- 

 laboration such as yours with Sir John Lawes, already extending 

 over a period of upward of fifty years, is unexampled in the an- 

 nals of science. I venture to hope for an extended prolongation 

 of these joint labors, and trust that the names of Lawes and Gil- 

 bert, which for so many years have been almost inseparable, may 

 survive in happy conjunction for centuries to come." 



The address from members of the Royal Agricultural Society 

 to Mr. Gilbert declared that " in the organizing and systematic 

 arrangement and record of the researches conducted at Rotham- 

 sted you have had a leading share ; and you have there set before 

 us a model of what all work and experimental inquiry should be. 

 Your investigations into the applications of chemistry to the 

 cultivation of crops and the feeding of live stock have been of the 

 highest possible importance to the practical agriculturist, and the 

 sincere thanks of the agricultural community at large are due 

 and are hereby tendered to you for the scientific skill and inde- 

 fatigable industry which you have brought to bear upon the con- 

 duct of the Rothamsted researches. The Royal Agricultural 

 Society of England is proud of ranking you among its honorary 

 members, and it desires to take this opportunity of expressing its 

 indebtedness to you for your ever-ready counsel and assistance, 

 as well as for the many admirable and exhaustive papers which, 

 in conjunction with Sir John Lawes, you have contributed to the 

 society's journal."
