G 22 Quarterly Report of the Chemical Committee, July, 1893. 
Dr. Yoelcker then wrote to Colonel Levett : — 
May 31, 1893. 
Dear Col. Levett, — A manure which is sold and invoiced (as your 
purchase was) as “ Pure Dissolved Dones ” should he made of “ raw bone and 
acid only,” and any admixture,, be it gypsum, or blood, or anything else, 
constitutes adulteration. 
Good manufacturers have no difficulty whatever in making dissolved 
bones in the way required. 
The admixture of dried blood is reprehensible, as leading the purchaser 
to believe that he is buying a manure the whole of the nitrogen of which is 
derived from raw bone. . . . — Yours faithfully, 
Col. Levett. ' J. Augustus Yoelcker.

Col. Levett. 
Sir, — In reply to yours of the 1st instant, we are surprised and very 
sorry to find that there was a small quantity of blood in the last lot of dis- 
solved bone supplied to you. On inquiry this morning our foreman explains 
it by the season being advanced and the stock low ; there was not quite 
enough pure bone to execute the order, and a little turnip manure was put 
into it to make up the weight : this contains blood, and will account for the 
slight trace discovered by the analyst. 
The manure was manufactured here, and we have no doubt that the 
report of the analysis is correct. 
We much regret the occurrence and are willing to make any concession 
you may require. — Yours obediently, Chaplin & Vincent. 
The two following cases refer to refuse materials of little 
value, and sold under the names “ Fish Bone Manure” and “Fish 
Manure.”

a sample of “ Fish Bone Manure,” which cost 31 . 10s. per ton.
