In an experiment made by Russell and Goodwin at the Wye 

 Agricultural College the beasts were fed upon roots, hay, and 

 linseed cake, a comparison being made between linseed cake 

 poor and rich in oil respectively. The feeding lasted for 

 twelve weeks, and the litter was composed of a bottom layer 

 of peat moss to which straw was added at the rate of 28 lb. 

 per week. Table VI shows the results obtained.

The dung was sampled immediately the experiment was over, 

 while the manure was still tight under the feet of the animals ; 

 the experiment also took place during the winter months, yet 

 the loss still amounted to nearly 15 per cent, of the total nitro- 

 gen. It is noteworthy that all the experiments quoted show 

 practically this same loss of 15 per cent, for the first stage of the 

 dung-making process under the best conditions. Not only
