3GG Quarterly Report of the Chemical Committee, June, 1893. 
To this Dr. Yoelcker replied : — 
It. Boutflour, Esq. May 9, 1893. 
Dear Sir, — I am in receipt of your further letter. 
The only point which the manufacturers appear to have dealt with is 
that of the actual deficiency as shown in the figures of analysis. 
Taking this point first, I should by no means be prepared to accept the 
manufacturers’ method of calculating. The guarantee was for a minimum 
of 32 per cent, of total phosphates, and you have only received 294 ; you 
are therefore entitled to claim for the 21 per cent, of phosphates, as well 
as for the deficiency of ammonia. 
I make it a rule not to fix any money values on manures, and I cannot 
do so here ; I can only tell you in the general terms I have, that I call the 
manure a dear one. 
But there remains the important point, the one which, as I said, I am 
principally concerned with — viz. that the manure is not, and ought not to he 
called, “vitriolated bones”; and I want to hear what explanation the 
manufacturers have to give in respect to this. 
As you purchased the manure for “ vitriolated bones,” and my report 
tells you that it is not of this nature, I consider you would be justified in 
returning the manure as not being up to the description given. — Yours 
faithfully, J. Augustus Yoelcker. 
Mr. Boutflour wrote on May 18 to say that the further ex- 
planation given by the manufacturer was that there must have been 
some mistake on the part of his employe's. 
Ultimately a reduction of 35s. per ton was made. 
The two following cases show the necessity of the giving of 
an invoice, and of having the materials correctly described on the 
invoice : — 
5. Mr. Thomas Trinder, of The N upend, near Malvern, sent on 
March 1 a sample of what he said he had purchased as “ Linseed 
Cake.” 
Two tons had been ordered from a local agent, the price being 
81. 10s. per ton delivered, with no discount, 
Mr. Trinder stated that he had been giving it to sheep, mixed 
with hay chaff and cut swedes, and that during the time they had 
been feeding on it he had lost several sheep. 
Dr. Yoelcker’s report on the cake was : —
