The conical glass with its flared rim and bulbous base, is a Collectible piece, perhaps used in early laboratories and/or as an apothecary measuring device.  

I've taken pictures all around the conical area, along with the top and bottom views.  There is raised lettering & numbering for the measurements on the glass which reads "TABLE 2" with a "1" below it in the left front section (See pic #2) and reads "8 TEA" with a "4", "2", "1", and "1/2" below it in the right front section (See pic #5).  It has two etched lines near the top rim to show how far to pour in the ingredients (See pics #6 & #7).

On the base, three areas are named in the Early Philadelphia, PA area - "Balbirnie" + "Germantown" + "Phila".  Laboratories & Pharmaceutical Companies were prevalent in that area in the early 1900's.  Interesting = "Balbirnie" is a surname with early roots in Pennsylvania specifically with Charles Balbirnie, who settled in Philadelphia in 1827.  It is not a recognized town in PA today and is historically associated with Scottish origins.

The glass piece measures 1 7/8" tall x 2 1/4" across the top rim x 1 7/8" across the base.

The glass piece weighs 2.9 ounces without the packaging materials.
