 lowing conclusions. '- ' • '' ' inv: > ..■.'.v<

 its aggregate form of calculus; provided their actio^t be

 nated, nay, the super-carbortated, exert similar influence, ' 

 though in an inferior degree. That lime, even in the 

 small proportion it presents itself to us in lime-Avatei<y isi a

 even the caustic alkali, in any state of dilution that the 

 latter can be appHed to the living body. That, finding
