280 Proceedings of the Boyal Physical Society. 



Since my paper was communicated to this Society (March 

 18th, 1885), various chemists have published results verify- 

 ing my figures and conclusions, and amongst these I may 

 refer to the series of articles which have appeared in the 

 Scottish Agricultural Gazette by Sir J. B. Lawes, Bart., 

 r.E.S., etc. ; by Clifford Kichardson, Esq., Assistant Chemist, 

 U.S. Department of Agriculture {Jour. Chem. Soc, vol. xlvii., 

 p. 80) ; and by Dr A. P. Aitken in his report to the 

 Chemical Department of the Highland and Agricultural 

 Society (Trans. H. and A. Soc, 1885, vol. xvii., p. 397). 



Since the date of my previous paper, I have conducted a 

 series of tests and analyses for the purpose of identifying 

 and quantitatively determining the various conditions in 

 which nitrogen exists in the ensilage and also the acids 

 present. 



Doubtless the fermentations and decompositions may vary 

 under diverse conditions in the silo, but for the purposes of 

 the present notes, I have confined myself to one somewhat 

 acid sample. 



The material had been made from green barley and pease 

 mixed with rye-grass, etc. It was in good condition, and as 

 the various tests had all been carefully considered and laid 

 down previous to the receipt of the sample, no time was 

 given for any further or new actions to be set up, such as 

 are found to be caused by the prolonged action of oxygen 

 ladened air. 



Analysed under the ordinary conditions, the following 

 results were obtained : —
