The microscopic examination confirmed the analysis, and 
showed that the cake was made from dirty linseed, containing 
numerous weed-seeds, and was not a pure linseed-cake. 
In reply to the usual inquiries, Mr. Middleton informed Dr. 
Voelcker that he boujjht five tons of the cake, at 10/. 10s. per

respectable dealers, who on being made acquainted with the 
unfavourable report of the cake, made an allowance of 11. per 
ton to Mr. Middleton, who does not wish their names pub- 
lished.
