Stump the German

[Eva Elisabeth]

Sure, as you like it. I tried this question once, but it interfered with one on another thread. I'll give it a second try. (And it absolutely fits to the season!)
In summer 1861, Mary sent her niece, Julia Edwards Baker (Elizabeth's daughter), a very special present when Julia was going to have her children christened.
What was this present?

I had already given this hint#1: It was in a bottle.
