Wet drug jar.

The inscription means "syrupus croci" or "syrup of saffron (crocus sativus)."
"Infuse of the best English saffron 3 i. [one drachm/60 grains] in lb 1. [one pound/12 ounces] of canary. Let it stand close stop'd in a gentle warmth two or three days; then press out the wine, and melt it in sugar that is very fine 3 xx., which will give it a proper consistence. ... This is much us'd, and is expected to have all the virtues of the simple from whence it is made: it may be given almost at pleasure, and is much prescrib'd for children juleps." See J. Quincy, A compleat English dispensatory, 1718, p. 386-387.

The apothecary jar is bulbous on a spreading foot with a spout on opposite sides of the label. The body of the jar is decorated in blue with a cherub and shell design. The label is painted straight with an even outline in blue. The neck is ridged with a glazed rim and there is an unflanged spout with a flared rim at the rear. The hallowed base is glazed with an unglazed edge and "7" is painted in blue on the base. The jar does not have a strap handle. See Spencer Collection.
