Rem auks. — No. 9 is not taken in the calculation of the mean coefficient, on account of the decomposition of 
the sulphuric acid, which always lowers the coefficient ; the small quantity of lime in No. 9 depends probably 
upon the same decomposition, the sulphate of lime being changed into sulphuret of calcium, which again, by 
carbonic acid and water, is decomposed into sulphuretted hydrogen and carbonate of lime, which is precipitated.
