QUARTERLY REPORT OF THE CHEMICAL 
COMMITTEE, 
July, 1893. 
1. This case refers to a manure sold as “ Pure Dissolved 
English Bones,” but found on analysis to be adulterated with 
dried blood. 
Colonel T. J. Levett, of Wychnor Park, Burton-on-Trent, sent 
on May 13, 1893, a sample of two tons of what had been sold to 
him as “ Pure Dissolved English Bones,” at the price of %l. 10s. per 
ton, carriage paid, for cash. The vendors were Messrs. Chaplin & 
Vincent, Shrewsbury Estates Bone Manure Works, Weston, 
Stafford. 
The report returned by Dr. Voelcker was —

This is not pure dissolved bone, but contains admixture of dried blood, 
and the nitrogen is not derived merely from raw bone, as it should be. 
Meanwhile, another four tons had been ordered, to be of the 
same description as the first two tons. 
On Colonel Levett receiving Dr. Voelcker’s report he wrote to 
the vendors asking if the original guarantee had been kept to, and 
he received the following reply 
Weston, May 29, 1893. 
Col. Levett, Wychnor Park. 
Sir, — The last lot of manure we sent you was pure raw bone and 
vitriol, with about f cwt. to the ton of sulphate of lime, used as a drier, the 
other lots sent to you the drier was fine bone instead. We hope it has 
given satisfaction.. — We are, sir, yours faithfully, 
CHArLin & Vikcent,
