mel, instead of being suffered to concrete, as usual, into a 

 folid cake at the upper part of the vessel, is thrown out into 

 water, where it is instantlv condensed into a white powder 

 possessing the impalpable fineness of a precipitate. The 

 imperfect operations of grinding and levigating are thus su- 

 perseded, and the defects which have so generally been 

 complained of in the medicine from this cause remedied. 

 The product is lighter than levigated calomel, in conse- 

 quence of its greater comminution, three parts by weight 

 occupying the same space a.s Jive of the latter.

 speedily and oeconomically scoured, and without altering 

 its qualify.
