"(4) The proximate and ultimate composition of the animals in ditfer- 

 ent conditions as to age and. fatness, and the probable coin[)ositiou of 

 their increase in live weight during tlie fattening process. 



"(5) The composition of the solid and liquid excreta (the manure) in 

 relation to that of the food consumed. 



"(C) The loss or expenditure of constituents by respiration and the 

 cutaneous exhalations, that is, in the mere sustenance of the living 

 meat and-manure-making machine. [This has not been determined 

 with the respiration apparatus, but only by calculations based on the 

 amounts of dry Tuatter, ash, and nitrogen in the food, feces, and urine.] 



"(7) The yield of milk in relation to the food consumed to produce it, 

 and the intiuence of dilierent descriptions of food on the quantity' and 

 on the composition of the milk. * * * 



" Independently of the points of inquiry above enumerated, the results 

 have supplied data for the consideration of the following questions : 



"(1) The characteristic demaiuls of the animal body (fornitrogeneous or 

 nonnitrogeneous constituents of food) in the exercise of muscular power. 



"(2) The sources in the food of the fat produced in the animal body. 



''(3) The comparative characters of animal and vegetable food in 

 human dietaries." 



In these investigations several hundred animals, including cattle, 

 sheep, and pigs, have been used. 



An extensive investigation regarding to the use of the sewage of towns 

 as fertilizers for different crops, especially for grass, was carried on in 

 cooperation with the late Professor Way. The amount, composition, and 

 nutritive value of crops grown with this fertilizer were studied. 



"The chemistry of the malting process, the loss of food constituents 

 during its progress, and the comparative feeding value of barley and 

 malt have been investigated." 



Experiments commenced in 1884 are still in progress with reference 

 to the changes which croi)s undergo in the process of ensiling, and the 

 relative value of different kinds of silage as feeding stutfs. 



The records and results of the investigations by the Rothamsted 

 Station have been publislied in the Journal of the Royal Agricultural 

 Society of England^ Journal of the Chemical Society, Philosophical Transac- 

 tions of the Royal Society, Journal of the Society of Arts, Reports of the 

 BritiNh Association for the Advancement of Science, and elsewhere. The 

 list of articles published 1847-91, inclusive, embraces 115 titles. Sir John 

 Lawes has recently presented complete sets of these publications to a 

 considerable number of the agricultural colleges and experiment sta- 

 tions in this country. 



The Rothamsted Station has been maintained entirely from the pri- 

 vate resources of its founder, who, for the perpetuation of the work, 

 has placed in the hands of trustees a fund of £100,000, the laboratory, 

 and certain tracts of land. In accordance with the provisions of the 

 deed of trust the station is now carried on under a committee of man- 

 agement, of which Sir John is a member.
