his analysis. 
" We enclose his reply, from which you will observe that he makes it a 
rule to coiTespond only with the sender of the sample. Kindly return his

In answer to further inquiries, Dr. Voelcker received the fol- 
lowing letter from Mr. Monckton : — 
" The Cage, Tonbridge, Sept. 20, 1879. 
" Dear Sir, — I should have written before, but was anxious to afford you 
as much information as I could. The sample I sent you was taken from two 
bags only, as the rest were in the field, and nearly all used. I have portions 
of two bags that were left after the men had finished sowing, and from which 
Mr. of the importer's firm, who came to my farm on Tuesday last, 
carried away samples to be analysed. I enclose the analysis, which I 
received this morning, and at the same time an account from the firm I 
ordered the soda from, deducting 19s. dd. from the amount first charged, 
IGI. lis. 9c?. for 1 ton 1 cwt. 7 lbs. 
" Yours obediently, 
" Dr. A. Voelcker." " Frederick Moxckton."

This case is not without difficulty, and shows that some tam- 
pering with the cargo must have taken place ; but the Committee 
are unable to trace where this was done, and they publish the 
case to show that it is safer to buy by guarantee, and have all 
samples analysed. 
4. Mr. J. C. Wallis, Home Farm, Didlington, Brandon, 
Norfolk, steward to W. A. T. Amhurst, Esq., wrote on June the 
25th as follows : — 
"Hon. Sir, — I have a lot of manure I should like to have a sample of 
analysed on behalf of W. A. T. Ambmst, Esq., Didlington Hall (a member 
of the R.A.S.E.). May I request you to write me what your charges will be, 
and whether I may send it or not ? It is sold at 51. per ton, as a mixture of rape- 
cake, blood, and bones, for turnips. Will you give me an idea as to its value ?
