" Dear Sie, — I have mucli pleasure in giving you all the details respect* 
ing the supply of cakes to Mr. Mellisli. 
" In accordance with the objects of our Association, and to ensure purity 
of supply for our members, it is our custom to make contracts with leading 
manufacturers to supply us with cakes luider a guarantee which has been 
carefully settled after consideration of all that has been said on the question 
by yourself and other scientific authorities. 
" We have for some time had contracts of this kind with Messrs. 
Willows, Holt & Willows, the leading manufacturers in Hull. 
"The contracts with them have been worded as follows. They only 
differ from those we have with other makers in being a trifle lower in oil, 
Messrs. Willows, Holt & TN'illows being unwilling to go above lOJ per 
cent, in the guarantee, whilst some of our contractors will guarantee 11 per 
cent., and some 12 per cent, 
"Terms of Contract. 
" ' One and All ' Pure Linseed Cake guaranteed 95 per cent, purity. The 
average proportion of oil to be not less than lOi per cent., and sand not ex- 
ceeding 2 per cent. 
" We have paid IMessrs. Willows, Holt & Willows on the average quite 
30s. per ton extra price over their own ' pure ' cakes for * One and All ' 
quality made for us under these contracts, and, as a safeguard for our 
members, we have required the cakes to be stamped with our brand of ' One 
and All ' to keep them from getting mixed, &c. We have allowed the con- 
tractors to send out the cakes direct to our members, but have kept analysing 
deliveries at irregular intervals to keep a check on the make. 
" I'liese safeguards have appe.ared to us to suffice until the present case, 
as we lla^ e had only one previous complaint, and that did not appear to us 
to be proved upon investigation by our '' Complaints Committee.' 
In the present case, so soon as we heard from Mr. jNIellish, we sent 
down at our own cost to have sealed samples mutually drawn. Of these 
we sent one lot to Messrs. ^^'illows, Holt & Willows, and retained the 
second ourselves for test by you. A third set we have still here unopened. 
"Messrs. Willows, Holt & Willows had the cakes analysed by Mr. 
Penney, of Hull, and sent us the following report by him, which they 
thought we ought to accept as satisfactory : — 
" AjfALTSIS.
