to meet the eye, in consequence of his having everywhere 
substituted the editorial we in the place of the author’s per-

this treatment. 
Experience has shewn us, that alcoholized stavesacre, used as 
a hand-bath, destroyed in a couple of hours both the acarus and 
its eggs, lodged about the hands, and that the ointment of staves- 
acre, when the acarus occupied different regions of the body,
