Grange, Retford, which was sold as pure, and found bj me to 
be an inferior linseed-cake, made from badly screened linseed. 
A letter has since been received from Mr. Lister, who informs 
me that the matter has been settled, he having obtained a 
reduction in the price nearly to what I stated should be made by 
the dealer — a reduction, Mr. Lister says, he should not have 
received had it not been for my analysis and report. 
5. 1 have also to direct attention to the occurrence of castor- 
oil beans, which I detected by the microscope, in a sample of 
a compound feeding-cake that proved injurious to cattle. 
G. The following is an analysis showing the composition of 
a sample of a " Meat and Bone Manure," sent by Mr. Clement 
Baguley, The Oldfields, Pulford, Wrexham: — 
Moisture 26-17 
♦Organic matter 23-% 
Oxide of iron and alumina 8 '73 
Phosphate of lime '87 
Carbonate of lime 5 • 63 
Alkaline salts and magnesia 5 '39 
Insoluble siliceous matter (saiul) 29 "20 
100-00 
* Containing nitrogen 1*98 
Equal to ammonia 2-41 
The manure was thus very wet, and contained 29 per cent, of 
sand, and about 20 per cent, of other mineral matters of no 
intrinsic fertilising value. It yielded only 2^ per cent, of 
ammonia, and although sold as a " Bone and Meat Manure." 
did not contain quite 1 per cent, of phosphate of lime. It was 
scarcely worth '21. 2s. per ton. Mr. Baguley bought 10 tons, at 
5/. IO5. per ton, from the manufacturer. Not finding the bulk, 
on delivery, equal to the sample by which it was bought, Mr. 
Baguley went to the works, and wrote to me that he was satisfied 
with the appearance of things, and finally arranged to pay- 
according to my valuation. Mr. Baguley also put into my 
hands the following letter, which he had received from the 
vendors : — 
" Dear Sik, — Yours of the 8th instant is only to hand this morning. If 
the sample was fairly taken, the manure is certainly not worth what I have 
charged you for it. 
" There is no mistake in the article sent that I can find out, and I cannot 
account for its inferiority, unless the fact of its being the face of the heap, 
the first sent out, and the long exposure to the atmosphere of the doorway, 
may account for it in some way. 
" Its not having been put through the disintegrator, and throuj,h being
