" P.S. — They argue that you call no cake pure except 95 per cent., from 
which you take your standard, and that this cake was made from screened 
linseed. The price was 11. 15s. in Hull." 
4. Mr. R. H. Ashton, of Castleton, by Sheffield, on January 
11th, 1886, sent a sample of what was stated to be "bone-dust," 
the price asked being 5Z. per ton delivered. 
Dr. Voelcker reported as follows : — 
"January 12th, 1886. 
"Water 12-78 
*Organic matter 79-88 
Phosphate of lime -80 
Carbonate of lime, &c 6-30 
Insoluble siliceous matter -24 
100-00 
* Containing nitrogen -57

" This is not bone-dust at all, but almost worthless vegetable ivory. 
" J. Augustus Voelckee." 
Mr. Ashton subsequently wrote : — 
"January 22nd, 1886. 
Sib, — I am much obliged for your letter containing analysis of so-called 
bone-dust. The result is just what I expected. 
"Before sending sample to you, I had been in correspondence with my 
solicitor, so I have sent him invoice, &c., and am very much inclined to in- 
struct him to take proceedings against the vendors. Should I find that he 
does not recommend me to take legal measures, I will write you again. 
" The bone-dust was delivered and sown on the land whilst I was away 
from home, and on going over the land some time afterwards I found pieces 
of corozza-nuts that excited my suspicions, and fortunately I was able to 
obtain a samjjle from a neighbour who had some of the so-called bone-dust 
delivered the same day by the same parties. — I am. Sir, yours obediently, 
" RoBT. Hen. Ashton. 
" Dr. J. Augustus Voelcker." 
In consequence of Mr. Ashton's absence abroad no further 
action has been taken, and the vendor's name has not as yet 
been obtained.
