to 0'167 %(=ammoma, 0-202). It thus became evident that 

 no mere process of drying could give satisfactory results of 

 the amount of albumenoid nitrogen, as such figures would be 

 too high from the presence of fixed ammonia salts. The 

 nitrogen found during the last-mentioned experiment would 

 be equivalent to 1*044 % of albumenoids, and this deducted 

 from the previously corrected figures leaves 10'787 % as the 

 amount of albuminous material, equivalent to the remaining 

 nitrogen present in the ensilage, after calculating the results 

 as free from moisture. 



The volatile acid liquid was found to contain butyric acid, 

 and the acidity present when calculated into that acid gave 

 the following proportions : — 



/'r^^e (Volatile) Butyric Acid, 0-694% 



*Comhined ,, 2-489% 



Total Butyric Acid, 3-183% 



*=Butyrate of Ammonia, . . . . . 2-970% 



The fixed acid contained lactic acid, and the results, when 

 calculated into that acid, gave — 



i^rce (Fixed) Lactic Acid, 0*428% 



**ComUiied „ 1-073% 



Total Lactic Acid, ....... 1'501% 



**Lactate of Ammonia, 1 276% 



This last figure when calculated into ammonia is found to 

 be equal to — 



Ammonia as Lactate, ...... -202% 



Total i^iicec^ (Saline) Ammonia, .... 0-202% 



From these results we may recalculate the nitrogen present 

 in the sample with the following results : — 



NiTKOGEN PRESENT IN ENSILAGE. 



As Non-Ammoniacal Nitrogen, .... 1 -726% 



As Volatile ButyrsLte, . . , . . . . 0-396% 



As Fixed La.ct3ite, 0-167%
