Tiny Antique Bottles

These are two tiny antique bottles. The first still has the label for cuticle remover, and has a ground glass neck inside to fit a stopper. The second is a plain bottle with a small round ground glass circle on the side. It does not have a ground glass neck so I am not sure what the closure would look like, nor do I have any idea for what the bottle was originally used. Both bottles are about 2 inches high, and neither has any mark on the bottom. Has anyone seen a bottle like this before, or know what it's use may have been?
