give it me for nothing.” 
Up to December 1 Mr. Neale has received no reply, nor has he 
paid for the manure. 
4 . Mr. J. Hankinson, of Bavn-sley Hall, Bromsgrove, sent on 
October 8, a sample of manure which he described as “ Boiled 
Bones,” subsequently stating that it was ordered as “ Boiled Bones, 
and to be free from Blood.” The price was 51. per ton, less 10s. per 
ton for cash, delivered. Four tons had been purchased from the 
manufacturers. 
Mr. Hankinson, fancying that it w.as mixed with dried blood, 
sent a sample for analysis. 
Dr. Voelcker noticed that the manure was partially dissolved, 
and thought that possibly the manure had been intended for 
dissolved bones and not boiled bones. He accordingly gave the 
following Report : —

This is not a genuine sample of dissolved bones, but is made up with 
dried blood and other nitrogenous matter. The nitrogen accordingly is not 
derived purely from bone, as it ought to be. The sample is coarse and 
badly prepared, containing comparatively little fully dissolved bones. 
Mr. Hankinson confirmed what he had said, that he had ordered 
“Boiled Bones,” but added that when he told the vendor that lie 
had had the bones analysed, and that dried blood had been mixed 
with them, the vendor said that if he was not satisfied he could 
return them and he (the vendor) would pay the carriage back. 
Mr. Hankinson was unwilling to give the manufacturer’s name. 
Basic Slag. — The Committee think it desirable to draw the 
attention of intending purchasers of Basic Slag to the variable 
qualities of this material which are put upon the market. They 
advise that not only should a guarantee both of quality and fineness 
be obtained by the purchaser, but also that samples should be 
checked by analysis. 
In a case which recently occurred, a guarantee of from 37 to 42
