"Organic Manure Analysis 
"Made by the well-known chemists, Messrs. Herrings & Co., Aldersgate 
Street, London. 
Organic matter 25 • 0 
Soluble phosphates, &c 19 '5 
Alkaline salts 23 " 5 
Silica 7-5 
Moisture 24-5 
100-0 
"Ammonia 1*49 per cent, as given in another analysis by Prof. E. Kinch, 
F.C.S., F.I.G., &c., of the Koyal Agricultural College, Cirencester." 
Dr. Voelcker's report with the analysis was : — 
" June 10th, 188G. 
Moisture 48-35 
*Organic matter and salts of ammonia 22-11 
Phosphate of lime 1'67 
Carbonate of lime 10 • 76 
Magnesia, alkalies, &c 6-68 
Sand 10-43 
100-00 
Containing nitrogen -66 
Equal to ammonia - 80 
"You have just about twice as much useless water as the published 
analysis states the manure contains, and about half as much useful ammonia. 
Instead of 195 per cent, of phosphates you have only 1§ per cent., so that I 
suppose the remaining 18 per cent, is ' &'c.' (but 1 do not think the ' &c.' 
will do your field much good !) Your 21. per ton is not well expended in pur- 
chase of such poor stuff. " J. Augustus Voelcker." 
After some correspondence this case was closed by the receipt 
of the following letter : — 
" From Hamilton & Co., 118, High Street, Wandsworth, London, S.W. 
" To D. Davison, Esq., 
" Sedgefield, Ferry Hill, Co. Durham. " July 16th, 1886. 
" Dear Sir, — Eeferring to your letter of the 12th inst., we hear with sur- 
prise and regret such a bad account of the manure we had the pleasure of 
supplying to yon. We have been looking into the matter at our works, but 
arc unable to trace how the mistake occurred. We do not see how you 
arrive at the amount of 71. 16s., but we beg leave to enclose cheque for 6?., 
Avhich we trust you will accept in settlement of the matter, as the season is 
now too far advanced for us to replace the manure with other of the usual 
quality. Our manure has been tried against other special turnip manures 
with such advantage that we receive unsolicited testimonials to its value. 
The wet weather, doubtless, accounts for the extra moisture, but the phos- 
phates were evidently omitted through some blunder. 
"Apologising for the trouble inadvertently given you, and hoping to be 
favoured with your orders next season, — We remain, yours truly, 
" Hamilton & Co."
