the interests of truth, rather than my own advantage, to make 
known the chances of success of an operation, the efficacy of 
which has, doubtless through an unintentional error, heen

sy, and Lecanu have arrived at. the foHowing results. 
~ Ist. That the sulphuric acid at 66° will dissolve sulphate 
ef iron at a maximum, and become of a red color. 2d. That 
this solution passes readily to the maximum by the action of
