cent. The small stone and small piece of wood were of course accidentally 
in the cake. We note a little mould on one of the samples ; there was none 
when the cake left here. The close confinement in a truck under the hot 
sun must have produced this. We have opened the samples, and find them 
all right inside. We have made a usual delivery of this kind of cake. Any 
“ rubbish ” inadvertently sent we will take back, hut if you examine the 
bulk you will find none. — Yours faithfully, A. D. & Co. 
A request being made for the taking of fresh samples, this was 
done, one portion being sent to Dr. Yoelcker, who reported as 
follows : — 
B. Stanier, Esq. June 4, 1894. 
Dear Sir, — I have examined the further sample of cake. It is only 
fair to say that it does not contain nearly the quantity of weed seeds that 
the first sample did, though there is certainly too much for a “pure” cake. 
Nor is there as much sand, though the amount still reaches the high figure 
of 7\ per cent. The cake is mouldy just like the first one, and because of 
the sand and the condition, is not a fit cake to give to stock. 
If you crush the cake up and stir it in water you can see the sand settle 
down by itself. Outwardly, both samples look much alike, and I have 
kept some of the first one in case the vendors wish to have a piece of it. — 
Yours faithfully, J. Augustus Yoelcker. 
Correspondence then passed between the vendor and Messrs. 
Denniss & Co. 
Hull : June 4, 1894. 
Sir, — Yours received. We have had the samples analysed (the samples 
you sent), and find they give 4 per cent, less ash than the analysis you sent, 
also 2 per cent, more oil. The cakes were free from mould when they left 
here, and looked a usual delivery for this class of cake, which does not keep 
well in warm weather. We have never had these cakes so low in oil before, 
and fancy the mould has something to do with the low percentage (mould 
which came on after delivery here) ; the sample you had analysed is either not 
a fair one or is inaccurately analysed. 
We enclose copy of analysis of the pieces you sent us. We point out that 
we guaranteed nothing but oil. Any deficiency in this we shall be glad to 
pay for, allowance being made for the influence of mould, for which we are 
not responsible, for lessening the percentage. If you have any suggestions to 
make I shall be glad to hear from you. — Yours truly, 
(Signed) A. Denniss & Co.
