analysis guaranteed, but if a material be sold as “ steamed 
bones,” it should be bones merely steamed, and not those 
treated with sulphurous acid, or steamed bones with gypsum 
added to them, in both of which cases sulphate of lime is 
found in some quantity. The following are three instances

In the case of “A” it was admitted that gypsum had been 
added, and an allowance of 10Z. on a purchase of 25 tons was 
made. In“ B ”and “C ” the “sulphite process” had been adopted, 
and allowances were made in each instance. In a fourth case, 
not here reported (as the sender was not a member of the 
R.A.S.E.), a prosecution was instituted by the Lindsey (Lincoln- 
shire) County Council, and a fine with costs inflicted, the 
admission being made that gypsum had been added in order 
to get the material into dry condition. There is no objection 
either to the admixture of gypsum or the adoption of the 
“sulphite process,” so long as the fact be clearly stated and the 
material be not sold as “steamed bones” without qualification.
