376 Quarterly Reports of the Chemical Committee, 1883. 
1883, by Mr. Henry Pye, of St. Mary's Hall, Rochester, yielded 
on analysis the following results : — 
Moisture 12*08 
•Organic matter and water of combination . . 26 • 06 
Insoluble phosphates -96 
Sulphate of lime, alkaline salts, &:c 45* 97 
Oxide of iron and alumina 2*20 
Insoluble siliceous matter 12*73 
100-00 
* Containing nitrogen 1'09 
Equal to ammonia 1-32 
!Mr. Pye stated that the sample was part of two tons of this 
manure, which he had purchased also of the "South London 
Manure Company," represented by Mr. E. Reeves, at 51. 5s. per 
ton, and Dr. V oelcker reported to the purchaser as follows : — 
The sample of so-called nitro-phospbate which you sent me for analysis 
j'ou will see by the enclosed analysis contains no soluble and scarcely one per 
cent, of insoluble phospliate. It is a poor manure for roots and anything 
else, and I would not buy it if it were offered to me at 21. a ton. 
3. Messrs. W. and E. Marshall, of North Lynn, King's Lynn,^ 
sent on June 26th, 1883, a sample of a parcel of 20 tons of 
linseed-cake said to have been guaranteed " pure," and pur- 
chased at 11. 12s. Qd. per ton. The following is the result 
of the analysis of the cake : — 
Moisture 11*65 
Oil 8*56 
•Albuminous compounds (flesh-forming matters) 20 * 81 
Mucilage, sugar, and digestible fibre .. ,. 13*94 
Woody^fibre (cellulose) 20*24 
tMineral matter (ash) 18 * 80 
100*00 
* Containing; nitrogen 3*33 
t Including silica and sand 9*55 
Dr. Voelcker reported upon it as follows : — 
The sample of cake which you sent me, and which I notice was branded 
"Pure,"' I find is poor in oil and in albuminous compounds. It is made from 
dirty linseed, and largely adulterated with ground rice husks or some similar 
material, consisting chiefly of woody fibre. The cake in niy judgment is not 
worth 77. 12s. Gd. a ton, and I would advise }*ou not to use it, or, if you have 
used some of it, to i)lace the remainder at the disposal of the vendor, to let 
him remove it from your premises at his own cost. Such cake ought not to 
be sold as pure, and as it is a very inferior adulterated cake I would refuse 
to take it at any price. 
This cake was ordered and was delivered in ^Lay of last year, 
and it was purchased by a dealer as part of a small cargo which 
arrived by a sailing ship at Lynn from Hull. Mr. W. F. Marshall 
informed Dr. \ oelcker afterwards tliat he had returned this cake.
