"Both samples have admixture of common salt: No. 1 is fuvtber adul- 
terated with carbonate of lime (chalk), and No. 2 with sulphate of lime 
(gypsum). " J. Augustus Voelcker." 
Both lots, Kg. 1 of 4 tons and No. 2 of 3 tons, had been 
purchased from Mr. A. Welding, of 12 Darvven Street, Black- 
burn, who was the manufacturer. In each case the price 
charged was bl. 2s. Qd. delivered. On complaint being made, 
the maker gave an allowance at the rate of Is. per ton in the 
case of No. 1, and 20s, per ton in the case of No. 2. 
6. Mr. Arthur Martin, of Rempstone Hall, Loughborough, 
sent on April 15, 1889, a sample of manui'e for analysis. Two 
tons of this manure had bequ purchased from Messrs. Hamilton 
& Co., 98 High Street, Wandsworth, S.W., at the price of 21. 
per ton delivered, with 5 per cent, discount for cash. The 
manure was called " Hamilton & Co.'s Organic Manure," and 
the purchaser received a printed circular, stating that the 
manure contained 15'81 per cent, of soluble phosphate, 1'25 
per cent, of ammonia, and 10*75 per cent, of insoluble silicious 
matter. 
Dr. A^oelcker's analysis and report were as follows : — 
" May 8, 1889. 
Moisture 20-55 
' Orfjanic matter 19-40 
Tribasic phosphate of lime ..... •"7 
Oxide of iron and alumina ..... 11-97 
Carbonate of lime, &c. ..... 8-84 
Insoluble silicious matter ..... 38-41 
100-00 
Containing nitrogen -88 
Equal to ammonia 1-07 
" You will see that this is very different from the analysis published in 
the circular sent you. Instead of 15-8 per cent, of soluble phosphate, it has 
no soluble phosphate at all, and only | per cent, of phosphate of lime. In 
place of 10-75 per cent, of insoluble silicious matter, it has no less than 
38-4 per cent. 
" 1 would have nothing to do with it. " J. Augustus Voelcker." 
Mr, Martin complained to the makers, and ultimately the 
manure was returned to Messrs. Hamilton, who repaid the 
money and also the carriage. 
7, Mr. James Farmer, of Brownhills, St. Andrews, Fifeshire, 
sent on April 15, 1889, a sample of linseed-cake for analysis, 
upon which Dr. Voetckei; repbrte^ as follows : —
