What's in that bottle?

I've been looking at this bottle sitting in our bathroom for a couple of year's now, mind you it's more than a couple of year's old...a bottle of Spohn's Compound, a bottle that I inherited from my dad who is ditching his vintage bottle collection. A bottle that is inspiring to me, almost every time I look at it. A bottle worth sharing with friends, of a "Stimulating Expectorant for HORSES, MULES, DOGS, RABBITS, apparently one of those wonders of the early 1900's. A bottle that would tuck nicely inside of a LaMerde jacket for the occasion that a gentleman might need it.
