3. Mr. C. P. Harvey, of Sudborough, Thrapston, ordered on

" patent carbon fertiliser " for oats, the price being 41. a ton. 
The vendors were Messrs. Hewes, Hewes & Geary, of Coalville, 
near Leicester, they being also the manufacturers. The firm 
was described as the manufacturers of the Hygeian Disinfecting 
Powder and Hewes' Anti-incrustation Powder, &c. 
Dr. Voelcker's analysis gave the following results : —

"Dear Sir, — In reply to your favour of the 2oth, which has been 
handed to me, I herewith give you a full explanation of the analysis of the 
' Patent Carbon Fertiliser ' as supplied by our firm. 
" I will take the analysis as it stands. 
" 1st. — The moisture = 20-51 per cent. No doubt it will somewhat 
surprise you wheu I state that the moisture is the special feature of our 
manures, and it is not a simple stinking bone oil put in to acquire a suitable 
density for the manure, but a liquid extract distilled from solid excreta by 
our own special patent process, at a very considerable cost, and cannot bo 
supplied by any other firm in the world; the moisture in one tou of our 
manure is worth in itself to us 21. 15«., as we can sell it readily for turnip- 
dressing at 2/. per cask of 10 gals. I send you by this post sample of the 
liquid extract, twenty per cent, of which is equal as a fertiliser to twenty- 
five per cent, of soluble phosphates, and eight per cent, of sulphate of 
ammonia — we practically tried and proved it. 
" 2nd. — The organic matter is quite right, the percentage of nitrogen 
varies a little. The greater part of the ammonia would come offia analysis
