8. Mr. T. Coulson, of Langton, Malton, sent on February 6, 
1889, a sample of linseed-cake for analysis. He had been 
feeding beasts with this cake, and they had been taken ill, as 
well as some milking cows. Upon analysis the cake gave the 
following results : — 
" February 21, 1889. 
Moisture 15-29 
Oil . . 11-13 
' Albuminous compounds (tie.sli-forming matters) . 25-94 
Mucilage, sugar, and digestible fibre . . . 31-19 
"Woody fibre (cellulose) 9-67 
Mineral matter (ash) 6-78 
100-00 
' Containing nitrogen ..... 4-05 
" The linseed-cake is very impure indeed ; it contains an extremely large 
admixture of other seeds, notably rape, spurry, and hemp. Also it has a 
great deal of starchy matters. It is a cake I should not think of using. 
" J. Augustus Voelckbr." 
This cake was bought as a second-class cake, price 71. 10s. 
per ton in Hull. After the report it was exchanged for 95 per 
cent, pure cake. 
9. On August 24, 1888, Mr. R. A. Graves sent, on behalf 
of Miss Adelaide Watt, Speke Hall, near Liverpool, a sample of 
linseed-cake for analysis. This was taken from a 1-ton lot, 
bought in Liverpool. The cake was invoiced, " A Qty ^ Pure 
Lins. Cake," the price being 61. 10s. per ton, at stores. Dr. 
Voelcker's analysis and report were :— 
"August 31, 1888. 
Moisture 14-29 
Oil . . 12-77 
^ Albuminous compounds (flesh-forming matters) . 24-31 
Mucilage, sugar, and digestible fibre . . . 30-87 
Woody fibre (cellulose) 7-97 
^ Mineral matter (ash) 9-79 
100-00 
' Containing nitrogen ..... ^ 89 
■ Including sand ...... 4-75 
" This cake has a good deal of sand, and consequently is not pure. 
" J. Augustus Voelckee." 
On complaint being made, the vendors said that it was in 
their opinion quite impossible to get linseed-cake perfectly 
pure ; but that they fancied that the cake supplied was, com- 
mercially speaking, quite pure — that is to say, made of seed as 
imported, but not as free from sand as some of the more ex- 
pensive cakes. They subsequently expressed their willingness 
to meet Mr. Graves in the matter, which was ultimately settled 
by a deduction of 10s. on the ton.
