The loss in weight on the 30th of April, thus amounted to 

 only 13i per cent. ; but as rain had fallen shortly before the 

 weighing was made in April, the real loss in valuable fertilizing 

 matters is much greater than indicated by the direct Aveighing. 

 This will appear clearly wlien the composition of the entire 

 quantity of the manure spread in the open yard shall have been 

 stated. Before doing this, however, I shall endeavour to explain 

 the alterations which the spread manure underwent in t!ie course 

 of the experimental year. 



The third series of analj'ses, incorporated in the subjoined Table, 

 I trust will afford a sure guide in drawing satisfactoi'y conclusions.
