Quarterly Report of the Chemical Committee, July 1890. 637 
3 & 4. Mr. T. S. Walker, Kiveton Hall, Kiveton Park, Sheffield- 
sent on June 11, 1890, two samples of Pure Dissolved Bones for 
analysis. Both were invoiced " Pure Dissolved Bones." 
The following analyses were returned on June 1 9 : — 
Moisture . 905 9-85 
1 Organic matter and water of combination . 24 .35 23-80 
Monobasic phosphate of lime . . . 1G01 13-39 
Equal to tribasic phosphate of lime (bone 
phosphate) rendered soluble by acid . (25 0G) (20 98) 
Insoluble phosphates 15-59 2475 
Sulphate of lime, alkaline salts, &c. . . 32'51 27'36 
Insoluble silicious matter .... 2 49 - 85 
100-00 10000 
1 Containing nitrogen .... 179 1'24 
Equal to ammonia 218 151 
The analyses were accompanied by the following report : — 
Neither of the samples is pure dissolved bones — i.e. a manure made 
entirely from raw bones and acid. They do not contain admixture of 
mineral phosphate, but the bone used in the manufacture instead of being 
entirely ra%o bone is steamed or boiled bone. The ammonia, in consequence, 
is only about half what it would be if raw bone entirely had been xised. 
5. Mr. Alex. lies, jun., of the Park Farm, Fairford, sent on 
May 17, 1890, a sample of linseed cake for analysis. Three tons 
had been supplied at 71. 15s. delivered (cash at two months), by 
Mr. James Snowsell, Cirencester, agent for the Cotswold Association 
" for the supply of pure and unadulterated Artificial Manures and 
Feeding Stuffs." The manufacturers of the cake were Messrs. 
Walker & Smith, Limited, of Hull. When sending the sample, 
Mr. lies wrote : — " Strange to say, my lambs, fatting-sheep, and 
calves do not clean up the cake in their troughs." The following 
analysis was returned on May 29 : — 
Moisture 12«68\ 
Oil 7-09 
1 Albuminous compounds (flesh-forming matters) . 2475 
Mucilage, sugar, and digestible fibre . . . 33 - 23 
Woody fibre (cellulose) 13-26 
2 Mineral matter (ash) 9 04 
1 Containing nitrogen . . . 3-96 
2 Including sand .... 3 99 
An abominably dirty, impure cake. It contains a large admixture of 
hemp, rape, earth-nut, with some cotton-seed, and the seeds of locust-bean. 
Such a cake has no right to be called a linseed-cake. 
On the invoice it was described as " Lins. Cake," and Mr. 
lies also wrote : — 
In selling me this cake the vendor verbally guaranteed it to contain 
13 per cent. oil. ... I bought 2 tons, and he sent 3, saying it was lying 
100 00
