EFFECT OF DECOMPOSING ORGANIC MATTER ON 

 INSOLUBLE PHOSPHATE OF LIME. 



F. B. DANCY 



Some time ag;() I instituted a few rough ex])erinients with a 

 view to a.scertainino; if the process of cleconi])o.sition »f organic 

 matter, or the products of such decomposition, had any eifect on 

 tri-calcic phosphate of lime in the way of converting it, or any 

 part of it, into its soluble form. The first results were of such 

 a character that the exj)eriments were not carried on to the extent 

 originally contemplated, hut I thought it migiit be well to call 

 attention to them as far a.> thev went.
