"Dear Sie, — AVe are in receipt of your cheque, value 18/. 10s., for which 
we thank you. You remark that our cakes are not branded pure, nor are 
they invoiced as such. The Merchandise Marks Act put an end to that. 
Supposing a parcel of seed to contain 95 per cent, pure liuseed, when the oil 
is extracted from it the percentage of purity is decreased, whilst the 5 per 
cent, impurity remains, causing the percentage of impurity in the cako to be 
relatively higher ; consequently the cake is not pure in the eye of the law, 
and has no right to be branded as such. This is counsel's opinion, and this is 
the reason why we chans'ed the brand on our cake, putting on the initials of 
our firm so that it might be known. Again, you say that we have not 
proved to jou that Dr. Voelcker's remarks are incorrect. We can only say 
that his remarks are not correct, and on what he bases them we do not 
know — but they are sweeping and unjust. We beg to state the cake is not 
very impure, and does not contain a large quantity of foreign seeds, &c. &c. 
We have known an analyst represent a cake to contain a large quantity of 
cockle-seed, when there was not a single cockle-seed in it. The cake you got 
from us was made of fine Libau linseed, which was twice screened, and there 
was no substance, foreign or otherwise, added to it. The albuminoids were 
not very high, between 27 and 28 per cent. It does not follow from that 
that the cake was very impure, as we have known 05 per cent. Calcutta 
linseed to show in the cake only 23 per cent, albuminoids. The oil is very 
high. There is li per cent, sand in the ash, which is more than we should 
have expected considering how the seed was screened, but the quantity is not 
excessive. Our cakes usually show a somewhat better analysis, but this is not 
abad one. You mention the price you pay, and that you think you ought to 
have a pure cake. AVe can truly say that we have always sent you the best 
cake that we can make. We always buy the best seeds, and, although much 
the same in appearance, the cakes made from them vary considerably in 
analysis. We have not the slightest objection to guarantee our cakes made 
from 95 per cent, seed, and trust that what we have said will satisfy you. — 
Hemaining, dear sir, yours faithfully, "Robert Stepiiexson & Son." 
"We may state that twice this season we have received copies of Dr. 
Voelcker's analysis of our cakes from customers which have been very 
flattering."
