VIII. — Quarterly Report of the Chemical Committee, 
December, 1876. 
The Chemical Committee called attention to the following- 
cases. In No. 1 the crushers made compensation to the amount 
of 21. per ton. In No. 2 the dealer was a neighbour, and as too 
frequently happens, in consequence, the complainant refused to 
furnish further information on the subject. No. 3 was published 
to show that crushers who profess to have the most perfect 
machinery may yet, from carelessness or neglect of their 
machinery, be liable to send out an impure cake. No. 4 
showed how unscrupulous persons attempt to take advantage of 
the action of the Committee to cover their own carelessness or 
neglect of precaution in making their purchases. 
1. A sample of linseed-cake was sent to Dr. Voelcker for 
analysis by Mr. Robert Wyatt, of Acton Hill, Stafford. One 
ton had been bought by him as " pure linseed cake," at 121. 10s. 
per ton, from a dealer at , who stated that the cake had 
been obtained from a Hull firm, and that he believed it to be 
perfectly pure, as he had received a duplicate of the following 
warranty with it : —

as per order bearing date the day of , 187 , are made entirely 
from fine sound screened linseed, and free from any adulteration. 
" This warrant to be subject to the analysis of Dr. Voelcker or Professor 
Anderson.

The following is the analysis of the sample submitted to Dr. 
Voelcker : — 
Moisture 8 '41 
Oil 15*24 
* Albuminous compounds 25*88 
Mucilage, &c 32-39 
Woodv fibre 12-47

A microscopic examination showed that the cake was not 
pure, but was adulterated with earth-nut or ground-nut cake. 
On the agent being informed of Dr. Voelcker's report, he wrote 
to the crushers, and a correspondence ensued, which terminated 
with the following arrangement being made with the purchaser,, 
as stated by him in a letter to Dr. Voelcker : —
