160 Quarterly Report of the Chemical Committee, March, 1891. 
Bridgwater Oil Mills. Half a ton had been purchased at 8^. 5s. per 
ton. The following analysis and report was returned on February 6 : 
Moisture 12o0> 
Oil 10-76 
' Albuminous compounds (flesh-forming matters) . 26-50 
Mucilage, sugar, and digestible fibre . . . 32-04 
Woody fibre (cellulose) 8-30 
» Mineral matter (ash) 9-90/ 
' Con'iaining nitrogen ..... 4 08 
' Including sand 4 00 
In addition to the 4 per cent, of sand, the cake contains admixture of 
rape and starch-yielding seeds. It is an impure cake. 
The vendor, when spoken to as to the inferiority of the cake, 
stated that, being out of cake at the time, he bought this lot, and 
was selling it for 5s. per ton less than he gave for it. 
7. Mr. T. Holtby, of Cowlam, York, sent on February 13, 1891 
a sample of manure which he had purchased at 80s. per ton. The 
following analysis and report was returned on February 18, 1891 : 
Moisture 18-25 > 
' Organic matter . 16 05 
Sulphate of hme 45-54 
Oxide of iron, &c 2 44 
^ Phosphoric acid 1"77 
Sand 15-95 
' Containing nitrogen -44 
equal to ammonia -53 
- Equal to phosphate of lime .... 3 86 
This is a manure of but little value, aud the price asked is e.\travagant. 
It is half gypsum with about 4 per cent, of phosphate of lime, aud con- 
tains little more than this of any value. 
Mr. Holtby said he had not asked for any guarantee, and was 
unwilling to give vendor's name. 
The Committee have reason to know that a considerable amount 
of cake i.s being sold as " oV-cake " which is not made from pure 
linseed, but contains a large admixture of other seeds, some of whicla 
may be injurious to stock ; they would, therefore, warn farmere 
against purchasing " oil-cake " under the impression that they are 
getting "j^jure li?iseed-cake," a,nd they again wish to impress upon 
buyers the desirability of insisting that the invoice shall describe the 
purchase as " Pure Linseed-Cake."
