Sheffield's Dentifrice -- a correction

Sheffield's Dentifrice -- a correction

The correspondent who furnished the formula for a preparation said to resemble this, which was printed in last month's CIRCULAR, was unfortunate enough to write sodium bicarbonate where he meant to say precipitated chalk. We here reproduce the formula corrected accordingly:

Powdered white castile soap........................6 drs.
Precipitated chalk...........................................15 ozs.
Carmine, No. 40..............................................3 or 4 grs.
Sassafras flavoring (as below).....................100 mins
Glycerin, a sufficient quantity.

Rub the solids well together, add the falvoring in small portions during the constant trituration and then glycerin enough to form a thin paste.

Sassafras Flavoring.

Oil of sassafras..................5 1/2 drs.
Oil of cinnamon..................2 drs.
Oil of wintergreen..............1/2 dr.
Extract of vanilla................4 drs.
Alcohol................................4 drs.
Shake before using.
