I'able showing Loss in the different component parts of Experimental Heap, No. III., 

 Fresh Farmyard Manure (No. III.), Spread, at different periods of the Year; also Per- 

 centage of Loss and Loss per Ton of Fresh Manure. Quantities stated in Ibs. and Frac- 

 tions of Ibs. (N.B. The sign * prefixed to a number indicates Increase instead of Loss.) 



Experimental Heap (No. IV.), Well-rotten Dung, Exposed. Mixed 

 horse, cow, and pig manure. 



The fourth and last series of experiments was begun on the 

 5th of December, 1854, with a view of ascertaining whether or 

 not well-rotten manure is deteriorated in value more rapidly 

 than fresh dung, produced by the same description of animals. 

 The weighings were made on the same days on which the weight 

 of the three preceding experimental heaps were ascertained. In 

 the following Table the results of the direct weighings are stated :

 Dung, Exposed, and Percentage of Loss. 



Analysed at the same periods at which the weighings were 

 made, 



the following results were obtained :
