Tiie 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 arc stated :
