Analysis of specimens purchased from different sources in the open
market were made under our direction. The reports of the chemists show
that Tyree’s antiseptic powder contains no borax, or mere traces only,
and that it contains no alum, or mere traces only. Instead, the analyses
show that boric acid and zinc sulphate are the essential constituents.
The amounts of carbolic acid, thymol, menthol, etc., contained in the
powder, if present, were far below the quantities indicated by the
formula. The presence of glycerin could not be demonstrated, and if
present the amount must be very small.
