the following analysis : —

An examination of the preceding analyses will show that 
6/. 2s. Qd. is a fair price for a manure having the composition

Thompson stated that his order of 8 tons of this manure was 
executed on May the 9th in Hull. 
Mr. Thompson subsequently wrote to the Secretary as fol-
