330 Quarterly Reports of the Chemical Committee. 
The following is the analysis of this substance : — 
Moisture 27-08 
Organic matter 20-32 
Phosphate of lime 2-49 
Oxide of iron and ahimina 1-50 
Carbonate of lime, &c 15-58 
Alkaline salts 1-72 
Insoluble siliceous matter 31-31 
100-00 
Nitrogen .. .. -74 
Equal to ammonia -89 
In sending this analysis to Mr. Wallis, Dr. Voelcker stated 
that he would think twice about it before he decided to buy such 
stuff, if it were offered to him, at 11. Is. a ton. 
The following communication was received from Mr. Wallis, 
in answer to the usual inquiries : — 
" Dear Sib, — I tliauk you very much for analysis received. I am sorry to 
say it is pretty much as I expected. I had hoped it would turn out better. 
I only purchased a small quantity from the maker. I have written him, 
enclosing copy of your analysis, and stating that I do not intend paying 
more than your valuation unless compelled, and claiming damages ; I will 
let you know the result. I am not the only one bitten." 
Subsequently Mr. Wallis wrote as follows : — 
"Dear Sib, — The maker has receipted his bill for the manure you analysed 
for me, without payment. I had some trouble with him." 
The maker's name is not published, simply because Mr. 
Wallis threatened to have it published unless the bill was 
receipted without payment. It was a Norwich production. 
5. A sample of bone-dust, bought as pure ground bones, 
at 81. a ton, was sent by Mr. George Rodger, Arden House, 
Altrincham. On analysis it yielded the following results : — 
Moisture 22-45 
*Oi ganic matter 13-98 
Phosphate of lime 13-75 
Caustic lime 3-35 
Carbonate of lime, &c 27-11 
Insoluble siliceous matter (sand and earth) ., 19-36 
100-00 
*Con{aining nitrogen 1-02 
Equal to Ammonia 1-24 
This sample, it will be seen, was very damp and much 
adulterated with lime-rubbish, old mortar, sand, and brick-dust, 
and, in comparison with pure bone-dust selling at 8/. a ton, was 
scarcely worth 21. a ton. No particulars as regards the vendors 
could be obtained.
