" This is nearly up to the guaranteed analysis, but is certainly not Pure 
Dissolved Bones. "J. Augustus Voelcker." 
This manure Dr. Voelcker found on examination to contain 
some quantity of ground hoofs or horn mixed with it. Three tons 
of the manure had been supplied by Mr. F. D. Gibbons, of Sun 
Street, Horsely Fields, Wolverhampton, the manufacturers being 
Messrs. Morris & Griffin, Ceres Works, Wolverhampton. Pre- 
vious to the purchase Mr. Gibbons, the vendor, contracted 
in the following terms : — " I will deliver you pui-e Dissolved 
English Bones in first-rate condition at 5/. 15s. per ton, at 
Madeley Market Station, carriage paid ; nothing but pure English 
bones and acid only.'' Subsequently, on receiving the analysis, 
the vendor protested that he had sold a genuine article, writing 
as follows : — 
" To W. H. Webb, Esq., Cranmere, Bridgnorth. " July 13, 1889. 
" Dear Sir, — In reply to yonrs of this morning, please give Dr. Voelcker 
all the particulars be asks for, and say that the dissolved bonet* you had from 
me are pure, and that I am prepared to prove it.— Yours trulj', 
" F. D. Gibbons." 
Meantime the following correspondence ensued between 
Dr. Voelcker and the makers : — 
" Ceres Works, Wolverhampton : July 13, 1889. 
" Dear Dr. Voelcker, — A. few weeks ago we sold to a firm in the trade 
a few tons ol pure dissolved bones. Mr. Gibbons sold them to a Mr. "Webb ; 
he has sent a sample to yon, and in a note you say, ' they certainly are not 
pure dissolved bones.' Now it is most annoying to us, as we can absolutely 
prove them to be so, and as Mr. Gibbons saw the writer himself he guaranteed 
them such, and he personally (Mr. Fuller) saw that they were filled up from 
the right heap. They were taken from a heap made early in the season, so 
as to dry, and great care taken in dissolving them, as we do a large trade in 
them, and secure a chain of evidence in case of anything of the kind happen- 
ing. Our manager is prepared to swear that no kind of mineral phosphate 
was used. 
" You have evidently mistaken the sample. — Yours truly, 
"Morris & Griffin,"
