Odds are it's m(l) (milliliter) for liquids and m(g) (milligram) for solids, probably period shorthand as it would be assumed from the known methods of measuring for dispensing. If that is the case 1/8th of a grain would be 8 mg. per teaspoon, which sounds about right for a cough syrup of that era (codeine was the main active ingredient). The other stuff was probably there to make the product 'better' than the competition's blend.
Competition is good.
Remembered from way back, don't remember when, that it's not ml or mg.
That stuff looks too old to use that.
It might be a "minim" used for apothecary things:
